HC Deb 10 June 1985 vol 80 c359W
Mr. Sedgemore

asked the Secretary of State for Social Services how much ruthenium was supplied to British hospitals for cancer research for the latest three-monthly, six-monthly and yearly periods for which figures are available.

Mr. Kenneth Clarke

We do not routinely collect information on this subject. However, no cancer research commissioned by us involves the use of ruthenium and we are not aware of any being supplied for this purpose to other researchers.
