Abstract

The relationship between the radiation absorbed dose and the NMR longitudinal and transversal relaxation rates, R1 and R2, respectively, of a ceric sulphate dosimeter was examined. By adding copper sulphate, the R1 and R2 dose-responses were found to be linear up to 60 kGy with dose sensitivities of 13 x 10(-6) and 15 x 10(-6) s(-1) Gy(-1) , respectively. There is thus the potential for a three-dimensional ceric dosimeter for high dose applications, provided a suitable gelling substance is used.
