Radiation field characteristics and irradiation techniques for gamma irradiation facilities using spent fuel elements from the reactor HIFAR

Abstract

Experimental and surface gamma irradiations of various small volume of bulk materials can be carried out at Lucas Heights by using an array of spent fuel elements from the reactor HIFAR in an irradiation pond. Details of the gamma radiation fields available are given and the irradiation techniques are described. These include experimental irradiations at low, ambient, and above-ambient temperatures. Geometrical factors which affect the dose rate are taken into account to ensure that the materials receive the specified dose.
