LIGHTWEIGHT RECOVERABLE COSMIC-RAY DETECTORS. A FILM BADGE DOSIMETER
Abstract
A film badge dosimeter (RBLD) was devised to provide a rapid method for determining effective energies below 200 kev of an unknown electromagnetic radiation. The dose response of the RBLD was calibrated to x-radiation at several different effective energies as low as 24 kev to 198 kev. The film used in this dosimeter (the 510 emulsion) is the insensitive one of the 552 Dupont film packet. Data in this report correlate film densities with dose for 4 highenergy radiations. These radiations were Co(60) gamma, 14 Mev protons, 730 Mev protons, and 900 Mev alphas. A method to reduce film density variances arising from small differences in film processing is also described. A pre- exposed radiation-control film is developed simultaneously with each set of experi ental films. The net densities of the experimental films are then raised or lowered in the same proportion needed to give a net density of 1.6 for the radiation-control film.
