THRESHOLD LESIONS INDUCED IN PORCINE SKIN BY CO2 LASER RADIATION

Abstract

The skin of white pigs was exposed to CO2 laser radiation with varying combinations of power density and exposure time. The dose-response relationship for threshold burns has been determined for power densities within the range of 1 to 8 watts/sq cm and exposure times 0.4 to 18 sec. In the range from 1.5 to 8 watts/sq cm the data fit the equation H = 4.13 t to the minus .607 power where H = incident power density (watts/sq cm) and t = median effective exposure time (sec). Limited data suggest that below 1.5 watts/sq cm this relationship changes. The data provide information for establishing safety standards for CO2 laser radiation.
