[Electromagnetic radiofrequency radiation (microwaves): principles and criteria of standardization, threshold dose levels]. 1985

B I Davydov

This paper discusses the principles and criteria of standardization of electromagnetic radiation in the radiofrequency range. The concept of risk as a standardization criterion normally used in the radiobiology of ionizing radiation can also be employed in the standardization of electromagnetic radiation. It is recommended to use as major parameters of "harmfulness" longevity, cataract formation and genetic effects in vivo as well as mortality rate in the laboratory experiment. The value of 0.1% is taken for the primary risk level. The paper describes approaches to the extrapolation of experimental data concerning threshold effects. As follows from pertinent calculations, the specific absorption of the electromagnetic dose rate for the personnel is 0.4 W/kg during one hour exposure.
