In an attempt to correlate the genotoxic effects of non-ionizing and ionizing radiation, a chromosome aberration analysis of peripheral blood lymphocytes in 20 individuals, who were working in Croatian radio-relay stations was performed. Cells from 25 physicians and nurses who had been regularly exposed to ionizing radiation was also studied.

The results demonstrate that total number of chromosome aberrations in people exposed to ionizing or radiofrequency radiation (4.08 +/- 0.37 and 4.35 +/- 0.5 on 200 scored metaphases, respectively) were almost equally higher than those of non irradiated subjects. Acentric fragments were the most frequently seen type of aberration. The average numbers in examined groups (11.8 x 10-3 and 14.8 x 10-3 per cell, respectively), were significantly higher than 4.2 x 10-3, which was observed in unexposed individuals. Dicentric fragments were also frequent (4.8 x 10-3 and 6.25 x 10-3, respectively, vs. 0.52 x 10-3 in unexposed subjects). In contrast, the frequency of chromatid breaks increased only after ionizing radiation (3.8 x 10-3 vs. 0.26 x 10-3 in control).
