Aim of study (acc. to author)

In order to study the possible genotoxicity of microwaves, both continuous wave (CW) and 50 Hz amplitude-modulated (AM) radiation were used. Following microwave exposure of human blood samples, lymphocytes were analyzed by using the cytokinesis-block micronucleus technique.
