Radiolysis of Polychlorodibenzodioxins in Hexane.

In the radiolysis of 2,3,7,8-tetrachlorodibenzodioxin in n-hexane (dose 6.5 Mrad), the degree of its decomposition according to data of chromatographymass spectrometry is not less than 99.99995 rel. % (detection limit 2· 10−10 mass %). In this case, the less-chlorinated dibenzodioxins formed at lower irradiation doses are not detected.
