§ 74. Mr. Hector Hughes
asked the Secretary of State for the Home Department if he is aware that a new type of respirator has been invented, details of which have been sent to him, designed to protect wearers from nuclear radioactive fall-out; and what steps he is taking to make it available to the British public.
§ Mr. R. A. Butler
A simple "smog" mask worn in dusty conditions would give all the protection that is required against breathing in radioactive dust from which the internal risk is small compared with the external risk due to gamma radiation from the surrounding contaminated area. No respirator can give protection against this external gamma radiation.
