In the irradiation of liquid perfluoro-1-methyl-4-isoburylcyclohexane (MBC) with Co-60 gamma rays, stable perfluoroalkyl radicals are formed. This paper shows the dependence on dose of the concentration of stable radicals formed during the irradiation of MBC with Co-60 gamma rays at 300 degrees K. The EPR spectra of these radicals show a doublet and a triplet with splitting at 3.9 and 5.6 mT, respectively. On the basis of perfluoro compounds like MBC it is possible to create dosimetric systems with which the dose of gamma-irradiation can be determined against a background stream of fast neutrons, simply by measuring the concentration of stabilized radicals.
