§ Mr. FoulkesTo ask the Minister of Agriculture, Fisheries and Food if he will give the monthly figures for measured total beta radioactivity from the discharge from Sellafield sea pipeline and Hunterston A and B as derived from the operators' returns to his directorate of fisheries research; and the figures for the authorised discharge limits in each case, for each year since 1983.
§ Mr. Donald Thompson[holding answer 30 January 1989]:Authorised discharge limits for both Sellafield and Hunterston for the period 1983–87 are published in the Ministry's annual reports "Radioactivity in Surface and Coastal Waters of the British Isles", copies of which are available in the Library of the House.
Monthly records of radioactivity discharged from these sites are obtained by Departments in confidence. Annual data of discharges and of their radiological consequences are published.
