Exposure limits for optical radiation are expressed using the following quantities and units (Table 1). Irradiance, E (W mj2), and radiant exposure, H (J mj2), are used in describing the concepts of surface exposure dose rate and surface exposure dose from direct exposure to laser radiation. Radiance, L (W mj2 srj1)is
