§ 49. Dr. Strossasked the Minister of Labour how many factories, at the latest available date, were using radioactive isotopes; how many operate X-ray apparatus among those using sealed sources of ionising radiations; what is 86W the approximate number of workers exposed; and the number receiving blood examinations at regular intervals.
§ Mr. WoodMy information is that there are at present some 560 factories using radioactive isotopes. Some 475 factories use sealed sources of radioactive substances, and some 260 factories use X-ray apparatus; there are cases where both are used but I cannot say how many. In all, there are some 3,000 persons employed in the processes and two-thirds of these receive blood examinations.
