HC Deb 26 July 1982 vol 28 c390W
Mr. Donald Stewart

asked the Secretary of State for Defence what is his latest estimate of the period during which it will be unsafe for (a) animals and (b) humans to land on Gruinard Island.

Mr. Pattie

The likely duration of contamination, methods of decontamination, their potential effectiveness and their cost remain under intensive review. Following laboratory tests of a number of potential decontaminants, it is now planned to undertake field trials on Gruinard Island.
