3 An employer who provides any system of work or personal protective equipment pursuant to this regulation must take all reasonable steps to ensure that it is properly used or applied as the case may be.
4 Where it is appropriate to do so at the planning stage of radiation protection, an employer, in relation to any work with ionising radiation that it undertakes, must use dose constraints in restricting exposure to ionising radiation pursuant to paragraph (1).
5 An employer must establish the dose constraints referred to in paragraph (4) in terms of the effective or equivalent dose received by an individual over an appropriate period of time.
6 Without prejudice to paragraph (1), an employer who undertakes work with ionising radiation must ensure that—
(a) in relation to an employee who is pregnant, the conditions of exposure are such that, after the employee's employer has been notified of the pregnancy, the equivalent dose to the foetus is as low as is reasonably practicable and is unlikely to exceed 1 mSv during the remainder of the pregnancy; and
(b) in relation to an employee who is breastfeeding, that employee must not be engaged in any work involving a significant risk of intake of radionuclides or of bodily contamination.
7 Nothing in paragraph (6) requires the employer who undertakes work with ionising radiation to take any action in relation to an employee until that employee's employer has been notified in writing by the employee of the pregnancy or that the employee is breastfeeding and the employer who is undertaking the work with ionising radiation has been made aware, or should reasonably have been expected to be aware, of that notification.
8 Every employer must, for the purpose of determining whether the requirements of paragraph (1) are being met, ensure that an investigation is carried out without delay when the effective dose of ionising radiation received by any of its employees for the first time in any calendar year exceeds 15 mSv or such other lower effective dose as the employer may specify, which dose must be specified in writing in local rules made pursuant to regulation 18(1) or, where local rules are not required, by other suitable means.

10 Personal protective equipment

(c) the record or a copy of the record is kept until the person to whom the record relates has or would have attained the age of 75 years but in any event for at least 30 years from the date of the last entry made in it.
3 Subject to paragraph (4), an employer must ensure that there is a valid entry made by a relevant doctor in the health record of each of its employees to whom this regulation relates (other than employees who have received an overexposure and who are not classified persons) and an entry in the health record is valid—
(a) for 12 months from the date it was made or treated as made by virtue of paragraph (4);
(b) for such shorter period as is specified in the entry by the relevant doctor; or
(c) until cancelled by a relevant doctor by a further entry in the record.
4 For the purposes of paragraph (3)(a), a further entry in the health record of the same employee, where made not less than 11 months nor more than 13 months after the start of the current period of validity, is to be treated as if made at the end of that period.
5 Where a relevant doctor has certified in the health record of an employee that in their professional opinion that employee should not be engaged in work with ionising radiation or that the employee should only be so engaged under conditions specified by the relevant doctor in the health record, the employer must not permit that employee to be engaged in the work with ionising radiation, or only permit the employee to be engaged in the work in accordance with the conditions so specified, as the case may be.
6 Where a relevant doctor requires to inspect any workplace for the purpose of carrying out their functions under these Regulations the employer must permit them to do so.
7 An employer must make available to the relevant doctor the summary of the dose record kept by the employer pursuant to regulation 22(7) and such other records kept for the purposes of these Regulations as the relevant doctor may reasonably require.
8 Where an employee is aggrieved by a decision recorded in the health record by a relevant doctor the employee may, by an application in writing to the Executive made within 28 days of the date on which the employee was notified of the decision, apply for that decision to be reviewed in accordance with a procedure approved for the purposes of this paragraph by the Executive, and the result of that review must be notified to the employee and entered in the employee's health record in accordance with the approved procedure.

26 Investigation and notification of overexposure
1 Where an employer suspects or has been informed that any person is likely to have received an overexposure as a result of work with ionising radiation carried out by that employer, that employer must make an immediate investigation to determine whether there are circumstances which show beyond reasonable doubt that no overexposure could have occurred and, unless this is shown, the employer must—
(a) as soon as practicable notify the suspected overexposure to—
(i) the appropriate authority;
(ii) in the case of an employee of some other employer, that other employer; and
(iii) in the case of the employer's own employee, the relevant doctor;
(b) as soon as practicable take reasonable steps to notify the suspected overexposure to the person affected;
(c) make or arrange for such investigation of the circumstances of the exposure and an assessment of any relevant dose received as is necessary to determine, so far as is reasonably practicable, the measures, if any, required to be taken to prevent a recurrence of such overexposure; and
(d) immediately notify the results of the investigation and assessment referred to in sub-paragraph (c) to the persons and authorities mentioned in sub-paragraph (a) and must—
(i) in the case of the employer's employee, immediately notify that employee of the results of the investigation and assessment; or
(ii) in the case of a person who is not the employer's employee, where the investigation has shown that that person has received an overexposure, take all reasonable steps to notify that person of their overexposure.
2 An employer who makes any investigation pursuant to paragraph (1) must make a report of that investigation and must—
(a) in respect of an immediate investigation, keep that report or a copy of the report for at least 2 years from the date on which it was made; and
(b) in respect of an investigation made pursuant to paragraph (1)(c), keep that report or a copy of the report until the person to whom the record relates has or would have attained the age of 75 years but in any event for at least 30 years from the date on which it was made.
3 Where the person who received the overexposure is an employee who has a dose record, the employee's employer must arrange for the assessment of the dose received to be entered into that dose record.
4 In this regulation “appropriate authority” means—
(a) in relation to overexposure as a result of work carried out on nuclear premises, the ONR;
(b) otherwise, the Executive.

27 Dose limitation for overexposed employees
1 Without prejudice to other requirements of these Regulations and in particular regulation 25(5), where an employee has been subjected to an overexposure paragraph (2) applies in relation to the employment of that employee on work with ionising radiation during the remainder of the dose limitation period, where that remaining period commences at the end of the personal dose assessment period in which that employee was subjected to the overexposure.
2 The employer must ensure that an employee to whom this regulation relates does not, during the remainder of the dose limitation period, receive a dose of ionising radiation greater than that proportion of any dose limit which is equal to the proportion that the remaining part of the dose limitation period bears to the whole of that period.
3 The employer must inform an employee who has been subjected to an overexposure of the dose limit which is applicable to that employee for the remainder of the relevant dose limitation period.
4 In this regulation, “dose limitation period” means, as appropriate, a calendar year or the period of five consecutive calendar years.

PART 6 ARRANGEMENTS FOR THE CONTROL OF RADIOACTIVE SUBSTANCES, ARTICLES AND EQUIPMENT

28 Sealed sources and articles containing or embodying radioactive substances

10 The employer must ensure that any employee in respect of whom regulation 12(2) applies is not exposed to ionising radiation to an extent that any dose limit specified in paragraphs 8 or 9 is exceeded.
11 An employer must not put into effect a system of dose limitation pursuant to regulation 12(2) unless—
(a) the radiation protection adviser and any employees who are affected have been consulted;
(b) any employees affected and the approved dosimetry service have been informed in writing of the decision and of the reasons for that decision; and
(c) notice has been given to the appropriate authority at least 28 days (or such shorter period as the appropriate authority may allow) before the decision is put into effect giving the reasons for the decision.
12 Where there is reasonable cause to believe that any employee has been exposed to an effective dose greater than 20 mSv in any calendar year, the employer must, as soon as is practicable—
(a) undertake an investigation into the circumstances of the exposure for the purpose of determining whether the dose limit referred to in paragraph 8 is likely to be complied with; and
(b) notify the appropriate authority of that suspected exposure.
13 An employer must review the decision to put into effect a system of dose limitation pursuant to regulation 12(2) at appropriate intervals and in any event not less than once every five years.

15 Where an employer puts into effect a system of dose limitation in pursuance of regulation 12(2), the employer must record the reasons for that decision and must ensure that the record is preserved until any person subject to the system of dose limitation under regulation 12(2) has or would have attained the age of 75 years but in any event for at least 30 years from the making of the record.
16 In any case where—
(a) the dose limits specified in paragraph 8 are being applied by an employer in respect of an employee; and
(b) the appropriate authority is not satisfied that it is impracticable for that employee to be subject to the dose limit specified in paragraph 1 of Part 1 of this Schedule,
the appropriate authority may require the employer to apply the dose limit specified in paragraph 1 of Part 1 with effect from such time as the appropriate authority may consider appropriate having regard to the interests of the employee concerned.
17 In any case where, as a result of a review undertaken pursuant to paragraph 13, an employer proposes to revert to an annual dose limitation in accordance with regulation 12(1), the appropriate authority may require the employer to defer the implementation of that decision to such time as the appropriate authority may consider appropriate having regard to the interests of the employee concerned.
18 Any person who is aggrieved by the decision of the appropriate authority taken pursuant to paragraphs 16 or 17 may appeal to the Secretary of State.
19 Sub-sections (2) to (6) of section 44 of the 1974 Act apply for the purposes of paragraph 18 as they apply to an appeal under section 44(1) of that Act.

PART 3 Quantity and concentration ratios for more than one radionuclide
Regulation 2(4)
1 For the purpose of Regulation 2(4)—
(a) the quantity ratio for more than one radionuclide is the sum of the quotients of the quantity of a radionuclide present Qp divided by the quantity of that radionuclide specified in the appropriate entry in Parts 1, 2 or 4 of this Schedule Qlim, namely—
(b) the concentration ratio for more than one radionuclide is the sum of the quotients of the concentration of a radionuclide present Cp divided by the concentration of that radionuclide specified in the appropriate entry in Parts 1 or 2 of this Schedule Clim, namely—
2 In any case where the isotopic composition of a radioactive substance is not known or is only partially known, the quantity or concentration ratio for that substance is to be calculated by using the values specified in the appropriate column in Part 1 of this Schedule for “other radionuclides not listed above” for any radionuclide that has not been identified or where the quantity or concentration of a radionuclide is uncertain, unless the employer can show that the use of some other value is appropriate in the circumstances of a particular case, when the employer may use that value.

SCHEDULE 8 Transitional provisions and savings
Regulation 41
1 (1) In this Schedule—
“the 1999 Regulations” means the Ionising Radiations Regulations 1999 ;
“restated provision” means any provision of these Regulations so far as it corresponds (with or without modification) to a provision of the 1999 Regulations;
“superseded provision” means any provision of the 1999 Regulations as it has effect immediately before 1st January 2018 so far as it corresponds (with or without modification) to a provision of these Regulations.
S.I. 1999/3232; relevant amending instruments are S.I. 2001/2626, S.I. 2001/2975, S.I.2008//960, S.I. 2010/675, S.I. 2011/1043, S.I. 2013/755, S.I. 2014/469, S.I. 2014/3248 and S.I. 2016/1154.
(2) In this Schedule references to things done include references to things omitted to be done.
2 (1) Any thing done, or having effect as if done, under or for the purposes of any superseded provision, if effective immediately before 1st January 2018, has effect, so far as is required for continuing its effect on and after that date, as if done under or for the purposes of the corresponding restated provision.
(2) Paragraph (1) does not apply in relation to an authorisation granted or notification made under the 1999 Regulations.
(3) The specific provisions in paragraphs 3 to 10 are not to be taken to affect the generality of paragraph (1).
3 Where on or before 5th February 2018 an employer commences work in respect of which a notification is required under regulation 5(2), it will be sufficient compliance with that regulation if the employer notifies the appropriate authority and provides the particulars required under regulation 5(2) on or before 5th February 2018.
4 In paragraph 3 “appropriate authority” has the same meaning as set out in regulation 5(6).
5 Where on or before 5th February 2018 a person carries out a registrable practice (within the meaning of regulation 6(1)) it will be sufficient compliance with regulation 6(3) if the person completes the registration procedure under that regulation on or before 5th February 2018.
6 A person who carries out a practice requiring consent under regulation 7 on or before 5th February 2018 is deemed to have been granted consent to carry out that practice under regulation 7(2) until 5th February 2018.
7 Where an employer has, in respect of an employee, applied the dose limits set out in paragraphs 9 to 11 of Schedule 4 to the 1999 Regulations in accordance with the requirements of regulation 11(2) of those Regulations and those dose limits have effect immediately before 1st January 2018, the appropriate authority is deemed to have approved, for the purposes of regulation 12(2) of these Regulations, the application of the dose limits, in respect of that employee, set out in paragraphs 9 to 11 of Schedule 3 to these Regulations.
8 In paragraph 7—
(a) “appropriate authority” has the same meaning as set out in regulation 12(4);
(b) the deemed approval granted by that paragraph is valid until the end of 5th February 2018.
9 A radiation passbook approved for the purposes of the 1999 Regulations and issued on or before 30th April 2018 in respect of a classified outside worker employed by an employer in Great Britain and which was at that date valid remains valid for such time as the worker to whom the passbook relates continues to be employed by the same employer.
10 Where a superseded provision provides a period of time within which an aggrieved person may apply for a decision to be reviewed, that period of time continues to apply on and after 1st January 2018 in relation to any decision notified to the aggrieved person before 1 January 2018.

(This note is not part of the Regulations)
These regulations revoke and supersede the Ionising Radiations Regulations 1999.
The Regulations impose duties on employers to protect employees and other persons against ionising radiation arising from work with radioactive substances and other sources of ionising radiation. The regulations also impose certain duties on employees.
The Regulations implement in part as respects Great Britain provisions of Council Directive 2013/59/Euratom (OJ No L13, 17.1.2014, p 1) laying down basic safety standards for protection against the dangers arising from exposure to ionising radiation, and repealing Directives 89/618/Euratom, 90/641/Euratom, 96/29/Euratom, 97/43/Euratom and 2003/122/Euratom.
The Regulations are divided into seven Parts.

Part 1 (Preliminary—Regulations 1–4)
The Regulations define the terms used in and the scope of application of the Regulations. For the purposes of the Regulations, an employer includes a self-employed person and an employee includes a self-employed person and a trainee.
Generally, the Regulations apply to any practice (as defined, and which encompasses various types of work), and to any other work carried out in an atmosphere of radon above a particular concentration. In the Regulations, work with ionising radiation means work to which the Regulations apply.

Part 2 (General principles and procedures—Regulations 5–13)
Regulation 5 requires certain work with ionising radiation to be notified to the appropriate authority (either the Health and Safety Executive (“the Executive”) or, where the work relates to particular nuclear-related sites, the Office for Nuclear Regulation (“the ONR”)). The work which requires notification is a residual category of work; amongst other exclusions, work which arises from practices which require registration under regulation 6 or require a consent under regulation 7 do not require notification.
Regulation 6 requires all practices to be registered with the appropriate authority other than those excluded from registration by regulation 6(2). Amongst other exclusions, practices consisting of work which is excluded from notification because the work falls within Schedule 1, are excluded from registration. Practices which require a consent under regulation 7, and practices which involve moderate amounts of radioactive material (not exceeding 1,000kg) where the activity concentration value of that material is less than the values in column 4 of Part 1 of Schedule 7, are also excluded from registration.
Regulation 7 requires an employer to obtain a consent from the appropriate authority to carry out certain practices.
Regulations 8 to 13—
(a) require employers to make a prior assessment of the risks arising from their work with ionising radiation, to make an assessment of the hazards likely to arise from that work and to prevent and limit the consequences of identifiable radiation accidents;
(b) require employers to take all reasonable steps to restrict as far as is reasonably practicable the extent to which employees and other persons are exposed to ionising radiation;
(c) require respiratory protective equipment used in work with ionising radiation to conform with agreed standards and require all personal protective equipment and other controls to be regularly examined and properly maintained;
(d) impose limits (specified in Schedule 3) on the doses of ionising radiation which employees and other persons may receive;
(e) require in certain circumstances the preparation of contingency plans for radiation accidents which are reasonably foreseeable.

Part 3 (Arrangements for the management of radiation protection—Regulations 14–16)
The Regulations require that employers consult radiation protection advisers in respect of matters specified in Schedule 4 and that employers ensure that adequate information, instruction and training is given to employees and other persons. Employers are required to co-operate by exchanging information to enable compliance by others with requirements to limit the exposure of employees to ionising radiation.

Part 4 (Designated areas—Regulations 17–20)
The Regulations—
(a) provide that areas in which persons need to follow special procedures to restrict exposure or in which persons are likely to receive more than specified doses of ionising radiation be designated as controlled or supervised areas;
(b) restrict entry into controlled areas to specified persons and circumstances;
(c) require radiation employers to set out appropriate local rules for controlled or supervised areas and to appoint radiation protection supervisors for the purpose of securing compliance with the Regulations;
(d) impose specified duties upon employers in relation to outside workers;
(e) require radiation levels to be monitored in controlled or supervised areas and provide for the maintenance and testing of monitoring equipment.

Part 5 (Classification and monitoring of persons—Regulations 21–27)
The Regulations require that employees who are likely to receive more than specified doses of ionising radiation be designated as classified persons, that doses received by classified persons be assessed by one or more dosimetry services approved by the Executive and that records of such doses are made and kept for each such person.
The Regulations also provide for—
(a) certain employees to be subject to medical surveillance;
(b) any cases in which an employee has received an overexposure to be investigated and notified to the appropriate authority;
(c) investigations to be made where employees are exposed above specified levels;
(d) modified dose limits for employees who have received an overexposure.

Part 6 (Arrangements for the control of radioactive substances, articles and equipment—Regulations 28–34)
The Regulations—
(a) require that where a radioactive substance is to be used as a source of ionising radiation, it should, whenever reasonably practicable, be in the form of a sealed source and that any articles embodying or containing radioactive substances are suitably designed, constructed, maintained and tested;
(b) cover the accounting for, keeping and moving of radioactive substances and require that incidents in which more than specified quantities of radioactive substances escape or are lost or stolen be notified to the appropriate authority;
(c) impose duties on manufacturers etc. and installers of articles for use in work with ionising radiation to ensure that such articles are designed, constructed and installed so as to restrict, so far as is reasonably practicable, exposure to ionising radiation;
(d) impose similar duties upon employers in relation to equipment used for medical exposures together with additional duties in relation to the testing and safe operation of such equipment;
(e) require employers to investigate any defect in medical equipment which may have resulted in a person receiving a dose of ionising radiation much greater than was intended and to notify the appropriate authority of such incidents;
(f) prohibit interference with sources of ionising radiation.

Part 7 (Duties of employees and miscellaneous—Regulations 35–43)
The Regulations impose duties upon employees engaged in carrying out work with ionising radiation. The Regulations also—
(a) provide for the approval of dosimetry services by the Executive;
(b) provide for a defence on contravention of certain regulations;
(c) provide for exemptions to be granted by the appropriate authority;
(d) extend the provision of the Regulations outside Great Britain;
(e) contain transitional provisions; and
(f) introduce modifications relating to the Ministry of Defence and visiting forces.
The Regulations contain transitional provisions and savings.
The Regulations make consequential and other modifications to the enactments specified in Schedule 9. In particular—
(a) the Health and Safety (Enforcing Authority) Regulations 1998 and the Health and Safety (Enforcing Authority for Railways and Other Guided Transport Systems) Regulations 2006 are modified to transfer enforcement responsibility for these Regulations in relation to road, rail and inland waterway to the ONR; and
(b) the Health and Safety and Nuclear (Fees) Regulations 2016 are modified to include an application fee of £25 for a registration under regulation 6 or a consent to carry out specified practices under regulation 7.
A full impact assessment of the effect that these Regulations would have on the costs of business and the voluntary sector is published with the Explanatory Memorandum, which is available alongside the instrument on www.legislation.gov.uk.
The transposition note in relation to the implementation of the Basis Safety Standards Directive is also published with the Explanatory Memorandum and available on that website. Copies of these documents are available in the libraries of both Houses of Parliament.
