HC Deb 06 April 1955 vol 539 c103W
82. Mr. Mason

asked the Under-Secretary of State for Air what steps are taken to plot the course of radio-active clouds passing over these islands following fission and thermo-nuclear tests; what measures are being adopted to protect our airmen from the higher roentgen percentage of radio-activity contained in these clouds as compared with the lower roentgen percentage in the general atmosphere; and what system of warning is being adopted to alert all aerodromes and aircraft of their approach.

Mr. Ward

The hon. Member has now received an assurance from my right hon. Friend the Minister of Works that there has been no danger over these islands from thermo-nuclear explosions. In the absence of any such danger, no special precautions are taken or are necessary.
