Assessment of Temperature Rise Suppression by Edge Losses during Irradiation

Abstract

A method to be utilized for human skin protection is described for determining: (1) the minimum aperture size required to yield temperature rise data free from edge loss effects in measurementss made at the center of a site during thermal irradiation of a semi-infinite solid; (2) the magnitude of edge losses due to restriction of the irradiated area to less than the 'no loss' size, and its variation with respect to irradiance level and exposure time; and (3) where the thermal properties of the material are known, the energy absorption rate. The latter, on comparison with the measured incident energy also yields a measure of the absorptivity of the materials.
