Abstract

The linearity for dose response and the dilution technique of deeply colored solution and others in titanium sulfate dosimeter were investigated.The dosimeter is a 0.01 M titanium sulfate solution saturated with nitrogen.All photometric measurements of titanium complex produced by irradiation were carried out at a wavelength of 410 nm.Dosimeter solutions were stable for 1080h at 25°C after irradiation.The dosimetry was not affected entirely by dose rates in the range of 104-106 R h-1, but affected considerably by irradiation temperatures.The dilution of deeply colored dosimeter solutions produced by high γ-ray dose irradiation was carried out succesfully using unirradiated dosimeter solutions (0.01 MTi (S04) 2 and 1N H2SO4) .This dosimeter saturated with nitrogen makes it possible to determine high γ-ray doses in the range from 104-106 Gy in accuracy ± 5 %.
