| Abstract: | Authors have elaborated a method which allows a digital computer to be applied for the calculaiton of the relative irradiation dose rates of the K-120.000 60Co gamma irradiation source with a specific activity of 80.000 Ci. The model used takes into consideration is the joint effect of 80 source-elements which were one-dimensional but of different activities and arranged in four layers one above the other, around one/two imaginary cylinder superficies. In possession of chemical or physical dosimetry data this method can be applied also for the calculation of the absolute irradiation dose ratres. According to the experiences obtained so far, over a distance of 6 cm-s from the source-elements the error of the computed absolute irradiation dose rate data is less than 5%. |
