Study type: Medical/biological study (experimental study)

The correlation between the frequency of micronuclei and specific chromosome aberrations in human lymphocytes exposed to microwave radiation in vitro. med./bio.

Published in: Mutation Research - Letters 1992; 281 (3): 181-186

Aim of study (acc. to author)

1) To explain the origin of micronuclei with regard to specific chromosome aberrations (acentric fragments and dicentric chromosomes), and 2) to detect the genotoxic effect of microwave radiation by analysis of structural chromosome aberrations and the micronucleus test in human lymphocytes.

Main outcome of study (acc. to author)

The results indicate that microwave radiation causes changes in the genome of somatic human cells. A positive correlation between micronuclei and specific chromosomal aberrations after exposure was observed. In the exposed sampels the presence of dicentric and ring chromosomes was established.
