Environmental Quality, Radiation Control

Rule R313-34

Requirements for Irradiators

Five-Year Notice of Review and Statement of Continuation

DAR File No.: 33367
Filed: 02/10/2010 07:41:23 AM


Concise explanation of the particular statutory provisions under which the rule is enacted and how these provisions authorize or require the rule:

Subsection 19-1-106(1) created the Radiation Control Board within the Department of Environmental Quality. Subsection 19-3-104(4) provides that the Board may make rules necessary for controlling exposure to sources of radiation that constitute a significant health hazard and to meet the requirements of federal law relating to radiation control.

Summary of written comments received during and since the last five-year review of the rule from interested persons supporting or opposing the rule:

This has not been a controversial rule. The Radiation Control Board recommends the continuation of this rule. No other comments have been received since the last five-year review.

Reasoned justification for continuation of the rule, including reasons why the agency disagrees with comments in opposition to the rule, if any:

This rule must be continued because it establishes the requirements for the possession and use of sealed sources containing radioactive materials in irradiators. These devices use gamma radiation to irradiate objects or materials. The rules provide for protection of public health and safety by controlling the use of panoramic irradiators that have either dry or wet storage of the radioactive sealed sources; underwater irradiators in which both the source and object being irradiated are under water; and irradiators whose dose rate exceeds 500 rad per hour at one meter from the radioactive source in air or in water.
