Abstract
Opti-chromic dosimetry systems which are commercially available and consist of radiochromic dye solutions in plastic tubing have been tested for measurement of Co-60 Gamma radiation at dose range of 0–0.3, 0–2.5, 0–30 KGy using detector types of FWT-70-40 and FWT-70-83. The required doses have been delivered from a hot-spot 3000 Irradiator with a dose rate of about 4.25 KGy/hr, at two irradiation temperatures of 22 and 50 C respectively. The response of the above detectors has been measured with FWT-98 reader at wavelengths of 600, 656 and 680 nm as appropriate. The results of this study and certain characteristics of this dosimetry system are presented.
