Abstract

The effect of two-step exposure of bacterial objects to infrared laser and microwave pulse radiations was studied. The effect is determined by the time interval between two excitation steps and pulse duration. It was shown that the biologically active dose of microwave radiation is much lower than that of infrared laser radiation; however, laser radiation induces a stronger cellular response. It was found that microwaves enhance the efficiency of infrared laser radiation.

Main findings

Two-step exposure effects depended on the time interval between exposures and pulse duration. The biologically active dose of microwave radiation was reported to be much lower than that of infrared laser radiation, while laser radiation induced a stronger cellular response. Microwaves were found to enhance the efficiency of infrared laser radiation.

Outcomes measured
