The RF protection guideline, submitted on 25 June 1990 by M.P.T. of Japan tells us that exposure of RF field to the operator of an RF transmitter does not harm on his health as long as the rated output at the transmitter is not beyond 7 W at frequencies 100kHz to 3GHz. However, there arises a new question whether it is true regardless of the exposure duration. To answer the question we must refer to the experimental results obtained by Kues et al. : corneal endothelial abnormalities were observed after the 4h exposure duration of 2.45GHz CW to monkey's eyes. We traced their experimental study applying RF power density of 40mW/cm^2 which is beyond the threshold, 30mW/cm^2,shown by Kues et al., but we have not observed the same abnormalities as they had done.
