HC Deb 31 July 1975 vol 896 c619W
Mr. Newens

asked the Secretary of State for Energy what types and quantities of radioactive waste have been discharged into the seas around the British Isles by nuclear power stations over the course of the past five years; and if he will make a statement.

Mr. Eadie

Returns made by operators under the Radioactive Substances Act 1960 show that from 1970–74, inclusive, the total of α and β emitters—including tritium—discharged to the sea by civil nuclear power stations in the United Kingdom was 1,850 curies, while the total tritium discharged was 3,300 curies. These totals were well within the limits set by authorisations given under the Act, and the resulting implied radioactivity dose to the public was well below the permitted limits defined by the International Commission on Radiological Protection.
