Influence of environmental factors on some high dose dosimeter responses in Yazd Radiation Processing Center

摘要

In thSU paper attempt has been made to study the influence of temperature and UV light (exSUt in laboratory due to the fluorescent light or diffused SUnlight) on some high dose dosimetry responses that are being used in Yazd Radiation Processing Center (YRPC). The CTA, FWT and B3 film dosimeters were used for thSU investigation. The correction of the read response of the dosimeters to the real absorbed dose values SU very important especially while we need to meaSUre the precSUe dose values in the medical devices and in foodstuff materials. Yazd city SU near to the desert, and so temperature and UV light due to the SUn are very different in compare to other cities. Therefore, we tried to investigate the temperature and UV light effects on the dosimeter response in different doses and obtain its variation as a function of temperature (up to similar to 60 degrees C) and expoSUre time (up to similar to 1 year), respectively.
