HC Deb 06 April 1955 vol 539 cc91-2W
Mr. Mason

asked the Minister of Transport and Civil Aviation what progress is being made in the fitting of radiation filters to British commercial aircraft; and what other measures are being adopted to ensure safety to passengers and crews in the event of flying through and in the vicinity of radioactive clouds.

Mr. Boyd-Carpenter

No action has been taken to fit radiation filters to British commercial aircraft; I am advised that there is no danger from radioactive clouds to passengers on any route on which British commercial aircraft fly.
