HC Deb 04 December 1962 vol 668 cc149-50W
41. Mr. Neave

asked the Parliamentary Secretary for Science what progress has been made into research on using depleted uranium metal in place of lead as shielding for strong gamma sources, containers and X-ray machines; and whether savings in space, weight and money can be effected by its use.

Mr. Denzil Freeth

Research into the safe use of depleted uranium for the shielding of high activity sources have been brought to a stage where it can be applied in industry. Depleted uranium is comparatively expensive but has unique advantages as a shielding material where savings in space or weight are paramount. The Atomic Energy Authority believes it will be possible to develop a small but useful market, both here and overseas, for this material for shielding purposes.
