| Setup | Five ml of whole blood in a test tube of 7.4 mm inner radius was positioned in the maximum field position of the TE10 mode whose electric field was parallel to the short side of the waveguide. |
| Additional info | The microwave signal was adjusted using a thermometer and a microcomputer to maintain a temperature of 36.1 °C. |

A marked increase in the frequency of chromosome aberrations (including dicentric chromosomes and acentric fragments) and micronuclei was found. But the microwave exposure did not influence the cell kinetics nor the sister chromatid exchange frequency.
