Proposed revision of the Canadian recommendations on radiofrequency-exposure protection.

In 1979, the Canadian Federal Government published a safety code which recommended limits of exposure to radiofrequency radiation at frequencies from 10 MHz to 300 GHz. This paper outlines and discusses proposed revisions to these recommendations. The main changes include an extension of the frequency range down to 10 kHz, a change in the exposure limits for the general public, and added recommendations on limiting body current upon contact with ungrounded objects. The rationale for the proposed limits refers to recent data on dosimetry and biological effects, and includes comparison with other national and international standards for radiofrequency exposure protection.
