[Joint effect on the body of ultrahigh-frequency electromagnetic energy and noise].
A brief review is presented of the new views and methodological approach in hygienic standardization of the combined effect of the physical factors of the environment - ultrahigh frequency electromagnetic energy and noise. In the determination of the biological significance of the factors with their isolated or combined effect and integral logarithmic scale was introduced for the levels studied - the value of the factors, expressed in dB. The results from noise effect of the order 80 dB [A], ultrahigh frequency (UHE) - electromagnetic energy (P = 60 microW/cm2) and their combination reveal the ratio of the restoration periods I:I.9:2.6. Reduced to the logarithmic scale, the identical noise levels and UHF- electromagnetic energy (according to the exemplary result) have different biological significance. If the biological significance of noise is accepted as unity then the activity of the electromagnetic energy from UHF-range is with I.35 higher than that of the noise. With the combined effect of those factors reduced to an integral scale of the levels, the relative biological significance of the noise, electromagnetic energy and their combination has the values I:I.35:2.I. In that way of processing and analysis of the results from multiprofile researches the combined effect of the physical factors could be standardized.
