Abstract : The effect of relative humidity (RH) and inositol on the lethal action of artifical sunlight has been studied. The letgality of these radiations isshown to be strongly dependent on RH provided the intensity of the light is not /oo great. A critical region between 55 and 65% RH exists in which there is an abrupt change in the sensitivity of airborne cells to all wavelengths tested. Inositol is shown to prevent radiation damage and, because of its structure, it is assumed to replaae water in the dried cells. Some ramifications of these findings with respect to the maintenance of cell integrity are discussed. (Author)
