Dynamics of Metabolic Parameters in Rats during Repeated Exposure to Modulated Low-Intensity UHF Radiation

Abstract

Metabolic parameters in rats were studied at various stages of repeated exposure to modulated low-intensity UHF radiation. The volume of O₂ consumption and level of heat release were reduced by day 4 of intermittent irradiation and remained low over the next 2 days in the absence of a source for electromagnetic radiation. The amount of expired CO₂ slightly increased over the first 3 sessions of irradiation, but significantly decreased in the recovery period on days 5 and 6. Changes in metabolic parameters were most significant on day 7 of the study. It was manifested in the decrease of O₂ consumption, CO₂ release, and intensity of heat exchange not only during irradiation, but also in the inter-exposure period. Electromagnetic radiation can induce a change of metabolic processes in mammals, which is most pronounced during repeated irradiation and persists even under physiological resting conditions.
