### sec.10 Disposal of radioactive material into sewerage system— Act , s 26 For section 26 (1) (a) of the Act — for disposal into a sewerage system of radioactive material containing only 1 of the radionuclides mentioned in schedule 3 , column 1—the maximum concentration prescribed is the concentration stated in column 4 of the schedule opposite the radionuclide; or for disposal into a sewerage system of radioactive material containing more than 1 of the radionuclides mentioned in schedule 3 , column 1—the maximum concentration prescribed is a concentration resulting in a disposal factor for the material of 1. For section 26 (2) of the Act , the point of disposal at which the concentration of the radionuclide in the radioactive material is to be decided is the point at, or immediately before, which the sewerage pipe leading from the premises from which the material is being disposed of joins the main reticulation line of the sewerage system. In this section— disposal factor , for radioactive material containing more than 1 of the radionuclides mentioned in schedule 3 , column 1, means the total of the amounts worked out for each of the radionuclides using the formula— where— A , for a radionuclide, means the amount for the radionuclide. C , for a radionuclide, means the radionuclide’s concentration, measured in Bq per cubic metre. MC , for a radionuclide, means the concentration stated in schedule 3 , column 4 opposite the radionuclide. (sec.10-ssec.1) For section 26 (1) (a) of the Act — for disposal into a sewerage system of radioactive material containing only 1 of the radionuclides mentioned in schedule 3 , column 1—the maximum concentration prescribed is the concentration stated in column 4 of the schedule opposite the radionuclide; or for disposal into a sewerage system of radioactive material containing more than 1 of the radionuclides mentioned in schedule 3 , column 1—the maximum concentration prescribed is a concentration resulting in a disposal factor for the material of 1. (sec.10-ssec.2) For section 26 (2) of the Act , the point of disposal at which the concentration of the radionuclide in the radioactive material is to be decided is the point at, or immediately before, which the sewerage pipe leading from the premises from which the material is being disposed of joins the main reticulation line of the sewerage system. (sec.10-ssec.3) In this section— disposal factor , for radioactive material containing more than 1 of the radionuclides mentioned in schedule 3 , column 1, means the total of the amounts worked out for each of the radionuclides using the formula— where— A , for a radionuclide, means the amount for the radionuclide. C , for a radionuclide, means the radionuclide’s concentration, measured in Bq per cubic metre. MC , for a radionuclide, means the concentration stated in schedule 3 , column 4 opposite the radionuclide. - (a) for disposal into a sewerage system of radioactive material containing only 1 of the radionuclides mentioned in schedule 3 , column 1—the maximum concentration prescribed is the concentration stated in column 4 of the schedule opposite the radionuclide; or - (b) for disposal into a sewerage system of radioactive material containing more than 1 of the radionuclides mentioned in schedule 3 , column 1—the maximum concentration prescribed is a concentration resulting in a disposal factor for the material of 1.
