The activity of alkaline phosphatase by the action of pulse-modulated microwave radiation was studied. The carrier frequency of radiation was 2375 MHz, the range of modulation pulse rate was 10-390 Hz with the on-off time ratio 2, and the specific absorption rate was 8 and 0.8 microW/cm². Time of exposure was 1 and 3 min under conditions of continuous temperature control.

It was shown that the activity of alkaline phosphatase depends on both modulation frequency and intensity of superhigh-frequency electromagnetic radiation.

At a frequency of 70 Hz, the activity of alkaline phosphatases increased 1.8-2.0 times.
