§ Mr. Altonasked the Prime Minister whether experiments were carried out to assess the effects of radiation using humans at Harwell and elsewhere during the 1940s and 1950s.
§ The Prime MinisterMedical investigations into the beneficial effects of ionising radiations involving humans have been carried out since the early 1920s. No experiments to assess the adverse effects of ionising radiation using humans were conducted at Harwell during the 1940s and 1950s, and I have no reason to believe that such experiments were conducted under United Kingdom auspices elsewhere.
