Abstract:

Present work deals with the study of radiation-induced dosimetric parameters of aqueous solutions of Sandalfix Orange C2RL (SO) dye within 0.1-100 kGy gamma dose range. A UV/VIS spectrophotometer was used for the spectrophotometric analysis of irradiated and un-irradiated sample solutions.Sample solutions were irradiated by Cs137?-ray source within 0.1-100 kGy dose range and sample solutions were analyzed in three different dose ranges i.e., 0.1-0.9kGy (low dosimetry), 1-9kGy (intermediate dosimetry) and 10-100 kGy (high dosimetry), respectively. The effect of gamma radiation on the response of co-factors of absorbance i.e., change in absorbance (?A) and relative absorbance (Ã) was discussed.The value of molar extinction coefficient was maximum at 430nm and decreased with respect to absorbed dose (D).
