Dosimetric intercomparison of research reactors

In-pile dosimetric intercomparison measurements were made in four reactors with two types of chemical dosimeters - perfluoromethyl cyclohexane, sensitive to γ radiation only, and oxalic acid dosemeters, sensitive to both γ-rays and non-thermalized neutrons - and with Ni-foils as a threshold detector. It was established that it was possible in one single run to obtain an absorbed dose value with a consistency of better than +- 20% in an unknown reactor core. (author)
