The study presents cytogenetic examinations carried out in subjects accidentally exposed to microwave radiation. Structural changes were followed up over the course of 30 weeks after the "accident" to demonstrate the persistence of such changes after acute exposure.

Results of chromosome aberration analysis of subjects before the accident showed only acentric fragments, chromatid and chromosome breaks which did not exceed 0.5-2.5%. All subjects showed a significantly increased number of chromosome aberrations. The total number of aberrations for the "accidentally" exposed group ranges from 3% to 33%, with the existence of a great number of unstable aberrations such as dicentrics and ring chromosomes. The results show a decrease in the total of chromosomal aberrations 30 days after the first sampling (dicentric and ring chromosomes are still present).
