The frequency of chromosome aberrations in a control population.
Chromosome aberration frequencies in a group of new entrants and non-radiation workers from this establishment have been studied using both block-staining and G-banding techniques. Increased levels of chromosome exchanges were found in those with a previous history of occupational or medical exposure to potential clastogens and in smokers. The possibility of an age effect was suggested. The study emphasizes the problems encountered in obtaining suitable control levels for comparison with occupational studies of exposure to clastogens.
