46.3 Licensees or registrants shall make the reports required by subsections 46.1 and 46.2 by initial contact by telephone to the Agency and shall confirm the initial contact immediately by email, express mail or facsimile to the Agency. The Agency shall reply to the written notification within 24 hours to discuss timing of follow-up action by the Agency.

46.4 The licensee or registrant shall prepare each report filed with the Agency pursuant to Section 46.0 so that names of individuals who have received exposure to sources of radiation are stated in a separate and detachable portion of the report.
