§ Mr. Hooleyasked the Secretary of State for Energy what percentage of the maximum permitted dose of radiation as laid down by the International Commission on Radiological Protection is received by workers for British Nuclear Fuels at Windscale most exposed to this hazard; and what proportion of the work force is regularly monitored.
§ Mr. Eadie:The most recent year for which published figures are available for radiation workers is 1976. For that year the Review of Radiation Exposure of the United Kingdom Population recently issued by the National Radiological Protection Board as NRPB R—77 shows that the average exposure of radiation workers at Windscale was 22 per cent. of the ICRP level. Of those workers about one quarter receved more than 30 per cent. of the ICRP level and six received more than 100 per cent. BNFL informs me that the figures for 1977 show an average exposure of 19 per cent, with 21 per cent. of the workers receiving more than 30 per cent. of the ICRP level and three receiving more than 100 per cent. About 90 per cent. of the work force at the Windscale and Calder Works B is regularly monitored.
