or that concentration which gives rise to a dose to a member of the public of 10 microsieverts per year calculated in accordance with the methodology used to calculate other concentrations in this table(1). | or that quantity which corresponds to 3,000m3 of aqueous radioactive waste up to the appropriate concentration as calculated in accordance with column 2. | or that quantity which corresponds to 10,000m3 of aqueous radioactive waste up to the appropriate concentration as calculated in accordance with column 2. |
(2) The summation rule in respect of column 2 of Table 7 is the sum of the quotients A/B where—
(a)“A” means the concentration in Bq/ litre of each radionuclide listed in column 1 of Table 7 that is present in aqueous waste which is not described in a row in column 1 of Table 6, and
(b)“B” means the concentration of that radionuclide specified in column 2 of Table 7.
(3) The summation rule in respect of column 3 of Table 7 is the sum of the quotients C/D where—
(a)“C” means the quantity in Bq of each radionuclide listed in column 1 of Table 7 that is present in the aqueous waste which is not described in a row in column 1 of Table 6 which is disposed of in the year, and
(b)“D” means the quantity of that radionuclide specified in column 3 of Table 7.
(4) The summation rule in respect of column 4 of Table 7 is the sum of the quotients C/E where—
(a)“C” means the quantity in Bq of each radionuclide listed in column 1 of Table 7 that is present in the aqueous waste which is not described in a row in column 1 of Table 6 which is disposed of in the year, and
(b)“E” means the quantity of that radionuclide specified in column 4 of Table 7.
The concentrations in this table were calculated using methods adopted by the Health Protection Agency in their document HPA-CRCE-005 - Derivation of Liquid Exclusion or Exemption Levels to Support the RSA93 Exemption Order Review, published in Chilton, Oxfordshire in August 2010 (ISBN 0-978-85951-673-0).
