Title Local lesions and chromosomal changes following irradiation from a cobalt source
Original title Lokální poškození a změny v chromozómovém obrazu při ozáření z radiokobaltového zdroje [in Czech]
Bibliographic information July 1979, Vol.31, No.6-7, p.230-234. Illus. 12 ref.
Abstract Following contact with a 60Co source with an activity of 3kCi at a hospital, a fitter developed necrosis of the 2nd and 5th fingers of the hand, requiring amputation. Chromosome studies revealed 13 dicentrics, corresponding to a whole-body dose equivalent of 1.2-1.6Gy (120-160rad). The fall in the number of these chromosomes in the peripheral blood lymphocytes during the 28 months after the accident followed a similar course to that seen in other cases reported in the literature. Deviations from the Poisson distribution seen in certain blood cells confirmed the hypothesis of non-uniform radiation. The accident illustrates the great hazard of handling unsealed gamma radiation sources.
