Description
A silver dichromate dosimeter was developed. With a spectrophotometer at wavelength of 350 nm, the molar linear absorption coefficient determined for Cr2O72- ions in perchloric acid solution is 315.9 +- 1.5 m2/mol. The G (-Cr2O72-) value for this system is (3.75 +- 0.02) x 10-8 mol/J and the dose conversion factor K is 8403 +- 42 Gy. It is found that the G value slightly depends on the initial concentration of dichromate ions. The irradiation temperature coefficient of G is -0.22%/degree C. The total uncertainty is +-4% (2σ) within the dose range from 0.4 to 5 kGy
