Investigation of the Effect of Temperature, Dose Rate and Short-term Post-irradiation Change on the Response of Various Types of Dosimeters to Cobalt-60 Gamma Radiation for Quality Assurance in Thailand
نویسنده
چکیده
The influences of combined effect of irradiation temperature from -80°C to 60°C and dose rate between 0.2 and 4 Gy/s on the gamma ray response of several commercial routine dosimeters (Harwell Red 4034, Gammachrome YR, FWT-60-00 radiochromic films, FWT-70-40 optical waveguides, GafChromic films, and Fuji CTA-FTR-125 films) were investigated for quality assurance in radiation processes. Besides, the studies of short term post-irradiation stability for the period of 2 h to 7 days are also presented. The overall results indicate the need for a calibration protocol under conditions of use.
