چکیده
|
Aqueous solutions of the sfg yellow crl commercial dye can be used as chemical dosimeters in the absorbed dose range 200-1000gy. the standard aqueous solutions were scanned by t80 uv/vis spectrophotometer for the determination of maximum wave length (λmax) which was found to be 448 nm. at this value, the absorbance (a) of irradiated samples was measured in uv region. the plot between concentration c and a gave a linear relationship and hence verified beer’s law which proved that these dye solutions can satisfactorily be used as the dye dosimeters in 200-1000gy gamma dose range.
