HC Deb 18 March 1957 vol 567 cc31-2
38. Mrs. Butler

asked the Minister of Health, as representing the Lord President of the Council, what is the latest available figure indicating the level of strontium in the bones of young children, and the amount by which this has increased since the figure for the level at November, 1955, was published in the Medical Research Council's Report of June, 1956.

Mr. Vosper

The average level of strontium 90 found during 1956 in the bones of young children in the United Kingdom was 0.67 units. The highest single level observed was 1.3 units, a level which does not differ significantly from the maximum of 1.2 units given in the report published by the Medical Research Council in June, 1956.

Mrs. Butler

Is the Minister aware that when the original measurements were taken only four hydrogen bombs had been exploded? It is believed that sixteen tests have now taken place. Is it not the case that the measurements taken in the United States six months ago showed a very high and rising level of strontium 90, which has been described as the most dangerous poison in the world? Will he assure the House that he will keep this matter under very close and constant review?

Mr. Vosper

The early part of the hon. Lady's question goes somewhat beyond my responsibility. There has been little or no change during the year in question and, of course, the matter is very much under review.

Mr. Hastings

In giving the very careful consideration to this matter which I know he is giving it, will the right hon. Gentleman remember that when X-rays were first used in this country no one realised that there was any danger, that it was not until there had been many deaths from carcinoma of the hands and other parts of the body that the damage was appreciated? Will he watch this matter with very great care?

Dr. Summerskill

In view of the increasing concern of reputable scientists about the hazards to life of these bomb explosions, has the Minister taken any advice more recent than that of the Medical Research Council last June?

Mr. Vosper

The original Question asked for the latest available figure, which I have given. I have said that investigation is continuing and that the matter is being watched very closely.
