Description/Abstract:
A DISCUSSION OF HUMAN EXPOSURE RISKS TO RADON AND THORON FROM AEC OPER ATED OR CONTROLLED PLANTS FOR ORE PROCESSING AND URANIUM REFINING IS O FFERED. DOSAGE CONCEPTS AND INHALATION HAZARDS ARE REVIEWED. THE VALUE FOR MAXIMUM ALLOWABLE CONCENTRATIONS (MAC) OF RADON USED BY THE NEW Y ORK OPERATIONS OFFICE (NYOO) IS EXAMINED AND LOWER FIGURES ARE SUGGEST ED. THE U.S. PUBLIC HEALTH SERVICE SURVEYED MEDIAN RADON CONCENTRATION IN 36 URANIUM MINES AND FOUND RADON CONCENTRATION TO BE HIGHER THAN T HE NYOO M.A.C. LEVEL. HOWEVER, CALCULATIONS ARE GIVEN THAT SUPPORT THE ASSUMPTION THAT THE NYOO M.A.C. LEVEL OF 1 X 10-10 CURIES PER LITER O F AIR IS AN ACCEPTABLE MAXIMUM DOSE. IT IS POINTED OUT THAT A CONSIDER ABLE AMOUNT OF RADIATION DOSAGE FROM RADON COMES FROM ITS DISINTEGRATI ON PRODUCTS THAT TEND TO REMAIN SUSPENDED IN THE AIR. TO VERIFY THESE DOSAGE CONCEPTS, A PROPOSAL FOR AN EXPERIMENTAL PROGRAM FOR EVALUATIO N OF RADIATION DOSAGE ASSOCIATED WITH RADON EXPOSURE IS OUTLINED.
