asked the Secretary of State for Energy (1) what is the ratio of radioactive emission from a typical or average (a) nuclear power station, (b) coal-fired station and (c) an ash disposal site, compared with the natural emission of a green field site.(2) what evidence there is of disease attributable to radiation for employees working in nuclear power stations, non-nuclear power stations, and ash disposal sites used for coal-fired power stations; and if any of these sources create a public health hazard.

I shall answer my hon. Friend as soon as possible.
