§ 64. Mr. Frank Allaun
asked the Minister of Housing and Local Government and Minister for Welsh Affairs, if he will state the extent of the recent increase of radioactivity in the drinking water supply of Manchester and Salford; and if increases have been notified in other areas.
§ Mr. Rippon
It is not expected that the recent nuclear weapon tests will bring about any appreciable deposition of long-lived radioactive material on the United Kingdom for several months. Preliminary tests for iodine-131 have not yet shown any measureable amount in Manchester and Salford drinking water or in the other supplies which have been sampled, but tests are continuing.
