Tóm tắt

The thin film PVA (polyvinyl alcohol) - bromocresol green (~15um) dosimeter was made for the applications in radiation technology. It's parameters before and after gamma irradiation have been studied using optical spectrometer UV-VIS JASCO-V-350 and film densitometer X-Rite Model 301. The results show that the specific wavelength of thin film is ~ 625nm and the sensitivity of thin film dosimeter is ~ 0.013 X 10-3 Gy-l in the dose range from 1 kGy to 140 kGy. The dose response junction of dosimeter was clearly described by the theory of energy transfer model.
