§ Miss Devlin
asked the Minister of State for Defence to what extent recent tests carried out by the Chemical Research Establishment at Porton have resolved the discrepancy caused by the lethal dose 205W quotient 50 assessment by the United States military research scientists; whether these studies have led to a reappraisal of the lethal dose quotient; what is his latest assessment; and whether the Medical Research Council was asked to provide personnel or otherwise to advise the investigation.
§ Mr. Ian Gilmour
Recent tests at Porton have confirmed previously published median lethal dosage figures which, for small animals, are approximately the same as those found by American researchers. The staff of the Medical Research Council have been consulted as appropriate.
