PERSONAL EXPOSURE INDICATOR
A personal indicator is described, which, together with newly developed types of film holders, permits the determination of the BETA and gamma dosage as well as that of thermal neutrons, between 20 and 200 rads. Beta and gamma rays are recorded in one holder fitted with Pb and Cu filters, whereas thermal neutrons are measured in another holder with Cd and Sn filters. The energy of x and gamma radiation is evaluated according to the difference in the blackening of film, with the aid of two Cu filters of different thickness, the extent of error being 25%. The dosage of BETA rays is indicated by the extent of blackening of the film, which lies under the hollow part of the holder. The films were sensitive for up to 1 month and were developed along with the control film, which was calibrated with the aid of standard radiation sources. (OTS)
