RESONANCE EFFECTS OF LOW-INTENSITY MODULA TED EHF FIELD - ALTERATION IN THE MOTOR-ACTIVITY OF PROTOZOA PARAMECIUM-CAUDATUM

The present work is concerned with the resonance influence of low-inte nsity pulse modulated millimeter waves on the motor activity of protoz oa Paramecium caudatum. A narrow-band dependence of the biological eff ect on the modulation frequency of EHF field and EHF carrier frequency has been revealed. The resonance phenomenon al a modulaton frequency of 0,0956 Hz has been observed at EHF radiation frequencies from 42,1 to 42,4 GHz, which manifests itself as a decrease of the motor activit y of P.caudatum. The obtained evidence allows a conclusion that the ef fect of modulated millimeter waves in our experiments is determined by the increase in the intracellular calcium concentration.
