HC Deb 03 July 1957 vol 572 c123W
99. Mr. Stokes

asked the Minister of Defence whether he will state the latest information regarding the extent to which there was harmful fall-out from the three hydrogen-bomb tests that recently took place off Christmas Island.

Mr. Sandys

Measurements taken on the ground and in the air at stations distributed widely in the operational area have so far revealed no distinguishable increase in radio-activity above the natural level, except in a few instances in which the increase was far too small to be harmful. No increased radio-activity has been detected in fish.
