[Effects of injurying and restoring the body of rats with microwave (2400 MHz) irradiation].

Abstract

In experiments on 2072 rats the thresholds of power density (PD) and the duration of microwave irradiation were obtained with the effect of destruction not more than 0.1%. The speed ratio of formation processes of destruction and regeneration depends on power density of microwave radiation and interpolates the exponential function. Previously obtained (from experiments on mice) and now published data allow the eifference to be established between mice and rats as species. Mice are more sensitive from the standpoint of time of achieving equal effects of destruction, half and full period of regeneration, the speed ratio between destruction and regeneration depending on PD of microwave radiation.

Main findings

In 2072 rats, thresholds of power density and irradiation duration were obtained that produced no more than 0.1% destruction. The ratio/speed of destruction versus regeneration depended on power density and followed an exponential relationship. Compared with previously reported mouse experiments, mice were described as more sensitive than rats in time to achieve equal destruction effects and in regeneration timing and speed ratios as a function of power density.

Outcomes measured

• tissue/body destruction threshold (≤0.1% destruction)
• regeneration after microwave irradiation
• species differences in sensitivity (rats vs mice)

Limitations

• No numerical values for power density thresholds or exposure durations are provided in the abstract.
• Outcome measures and how 'destruction' and 'regeneration' were assessed are not described in the abstract.
• Details of exposure setup (e.g., modulation, whole-body vs localized exposure) are not provided.
