Council Directive 2013/59/EuratomShow full title

ANNEX I U.K. Reference levels for public exposure as referred to in Articles 7 and 101

1. Without prejudice to reference levels set for equivalent doses, reference levels expressed in effective doses shall be set in the range of 1 to 20 mSv per year for existing exposure situations and 20 to 100 mSv (acute or annual) for emergency exposure situations. U.K.

2. In specific situations, a reference level below ranges referred to in point 1 may be considered, in particular: U.K.

(a)

a reference level below 20 mSv may be set in an emergency exposure situation where appropriate protection can be provided without causing a disproportionate detriment from the corresponding countermeasures or an excessive cost;

(b)

a reference level below 1 mSv per year may be set, where appropriate, in an existing exposure situation for specific source-related exposures or pathways of exposure.

3. For the transition from an emergency exposure situation to an existing exposure situation, appropriate reference levels shall be set, in particular upon the termination of long-term countermeasures such as relocation. U.K.

4. The reference levels set shall take account of the features of prevailing situations as well as societal criteria, which may include the following: U.K.

(a)

for exposures below or equal to 1 mSv per year, general information on the level of exposure, without specific consideration of individual exposures;

(b)

in the range up to or equal to 20 mSv per year, specific information to enable individuals to manage their own exposure, if possible;

(c)

in the range up to or equal to 100 mSv per year, assessment of individual doses and specific information on radiation risks and on available actions to reduce exposures.
