CYTOGENETIC EFFECTS IN ADOLESCENTS FROM D IFFERENT AREAS OF KEMEROVSKAYA-OBLAST

Considerable variations in the frequency of spontaneous chromosomal ab errations were revealed during a cytogenetic study of two groups of ad olescents from ecologically different areas of Kemerovskaya oblast'. I n a sample of adolescents living in an industrial center (the Kemerovo city), this parameter (1.4 +/- 0.37%) did not exceed the population a verage value, whereas adolescents of the same age from a mountain regi on with sparse industry (the town of Tashtagol) exhibited, on average, a frequency of 5.87 +/- 0.62%. An increased proportion of chromosomal -type aberrations in the qualitative spectrum of cytogenetic damage, w hich was observed for the group of adolescents from Tashtagol, suggest s that this population was exposed to radiation.
