Effects of millimeter-wave radiation on monolayer cell cultures. III. A search for frequency-specific athermal biological effects on protein synthesis. med./bio.

Published in: Bioelectromagnetics 1981; 2 (2): 151-159

Aim of study (acc. to author)

To investigate the effects of millimeter wave irradiation on protein synthesis in cultured hamster cells under controlled thermal conditions.

Background/further details

Protein synthesis was determined by measurement of optical densities of autoradiographes based on the incorporation of ³H-labeled methionine.
