title: Frequency of chromosomal lesions and damaged lymphocytes of workers occupationally exposed to x rays.
abstract: This paper analyzes the effects of x rays on workers exposed to radiation. In particular, this paper documents the emergence and frequency of non-specific chromosomal lesions with characteristic chromosomal aberrations and the number of damaged lymphocytes before, during, and after occupational exposure. Chromosomal changes were analyzed taking into consideration duration of exposure, dose, age, and sex. Correlation between aberrations and absorbed doses of x rays measured by thermoluminescence dosimeters is shown, as well as correlation between chromosomal lesions and damaged cells and the frequency of chromosomal aberrations. Chromosomal aberrations of karyotype diminish after exposures cease, but the number of non-specific lesions in karyotype do not decrease during the same period. The duration of exposure and age are not significant predictors of analyzed aberrations and lesions.
