§ Mr. Gordon Wilsonasked the Secretary of State for Social Services (1) if he has experienced any difficulty in obtaining supplies of Q tubes from Marconi-Elliott Advance Systems Ltd. for use with the Hiletron systems at Manchester and Glasgow;
(2) if he will make a statement on the future of the Hiletron neutron therapy research project at the Christie hospital, Manchester.
§ Dr. VaughanDifficulties have been experienced in obtaining adequate supplies 345W of Q tubes for concurrent clinical trials of neutron therapy at both Manchester and Glasgow. From the beginning of this year it has therefore been necessary to concentrate the available tubes in support of the Manchester trial which is now proceeding satisfactorily.
A decision on the additional investment required to provide sufficient tubes for completion of the Manchester trial by autumn 1981 is to be taken later this month.
