§ Mr. Andrew F. BennettTo ask the Secretary of State for Defence what is the total occupational whole body equivalent radiation exposure of(a) Chatham and (b) Devonport dockyard workers in milliSieverts, for each year since the onset of the nuclear programme.
§ Mr. NeubertThe cumulative radiation doses for all workers at Chatham and Devonport dockyards for each of the years 1979 to 1989 inclusive are shown in the table. These figures include the cumulative radiation doses of employees monitored for exposure to ionising radiations by the local issue of direct reading dosimeters while employed under a written system of work. Figures for earlier years are not readily available and could be provided only at disproportionate cost.

§ Mr. Alfred MorrisTo ask the Secretary of State for Defence, pursuant to his answer of 11 July,Official Report, column 245, concerning exposure to radiation, when the Under-Secretary of State for the Armed Forces expects to write to the right hon. Member for Manchester, Wythenshawe.
§ Mr. Archie HamiltonMy noble Friend the Under-Secretary of State for the Armed Forces will be writing to the right hon. Member shortly.
§ Mr. Andrew F. BennettTo ask the Secretary of State for Defence if he will give a breakdown for(a) Chatham and (b) Devonport dockyards of annual individual radiation exposure for workers in the bands of (i) 0 to 10, (ii) 10 to 20, (iii) 20 to 30, (iv) 30 to 40, (v) greater than 50, (vi) greater than 70 and (vii) greater than 100 milliSieverts for all years since the onset of nuclear work.
§ Mr. NeubertA breakdown of annual individual radiation doses for(a) Chatham and (b) Devonport dockyard workers for each of the years 1979–89 is given in the tables. A more detailed or alternative breakdown of the figures and data for years earlier than 1979 can be produced only at disproportionate cost.
