R 325.60703 Radiation protection guide.

Rule 3. (1) For normal environmental conditions and for incident electromagnetic energy of frequencies from 10 MHz to 100 GHz, the radiation protection guide is 10 mW/cm.2 (milliwatt per square centimeter) as averaged over any possible 0.1 hour period. This means the following: Power density: 10 mW/cm.2 for periods of 0.1 hour or more. Energy density: 1 mW-hr./cm.2 (milliwatt hour per square centimeter) during any 0.1 hour period. This guide applies whether the radiation is continuous or intermittent. (2) These formulated recommendations pertain to both whole body irradiation and partial body irradiation. Partial body irradiation must be included since it has been shown that some parts of the human body, such as eyes and testicles, may be harmed if exposed to incident radiation levels significantly in excess of the recommended levels.
