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 wattssq cm and exposure times 0.4 to 18 sec. In the range from 1.5 to 8 wattssq cm the data fit the equation H 4.13 t to the minus .607 power where H incident power density wattssq cm and t median effective exposure time sec. Limited data suggest that below 1.5 wattssq cm this relationship changes. The data provide information for establishing safety standards for CO2 laser radiation.
