Radioactive Materials Licensing

Renewals should be submitted on Form OR-RH-12. Amendments may be requested in a letter. The letter should clearly state what changes are requested, and should reference existing license conditions that are to be changed.


A copy of Form OR-RH-12 may be downloaded in Adobe .pdf format, or obtained from Jennifer Opila at (303) 692-3403.


For most licenses, there is no charge for the amendment. Generally, only licensees billed at an hourly rate will be charged for amendments.



Licenses are renewed every five (5) years. During that time, the Regulations change, and a licensee's procedures can change. By submitting a complete application every five (5) years, a licensee can both identify any changes in operations, and compare those operations against current regulations. 



The length of time required to process a license application depends on the workload at the time the request is received, the complexity of the request, and the completeness of the application. If all necessary information is included with the application, licensing requests are generally processed within two to three weeks.


Questions about radioactive materials licenses in Colorado should be directed to Jennifer Opila, Radioactive Materials Unit, at (303) 692-3403.





Any person or entity desiring to temporarily bring non-exempt radioactive material into Colorado must notify the Radiation Program at least three days prior to entering the State, and must receive approval from the Program before actual entrance into the State.


A current copy of the requestor's radioactive materials license must be on file with the Department, and the applicant must have a copy of the State of Colorado Rules and Regulations Pertaining to Radiation Control in possession while in Colorado.


Under Rules and Regulations Pertaining to Radiation Control,, the Department shall charge an annual management fee for persons operating in the state under reciprocity.  The fee for radioactive material brought into the state under reciprocity is equal to 75 percent of the appropriate annual fee. Reciprocal fees shall be due and payable prior to entry into the state.

A copy of the Reciprocity Request Form pdf file can be downloaded in Adobe .pdf format, or can be obtained from Carrie Romanchek, (303) 692-3431.  

A report of the program review must be on file as required in the Rules and Regulations Pertaining to Radiation Control 4.41. However, the report format is not specified and is left to the person conducting the inspection. The extremes in the reporting format range from one or two lines stating it has been accomplished, to the listing of every procedure and record as having been reviewed. The first extreme is not adequate and the last is usually too cumbersome.


The purpose of the self-inspection is to ascertain the quality of the radiation protection program and to report the results to management. A checklist is one easy way to complete this task. The checklist should list the conditions of the license, the Regulations which apply to the program, and good health physics practices. Each item of the report is then checked for adequacy, inadequacy, or if corrected during the inspection. The report can also be appended with comments for particular items. The report must include a signature and title of the individual conducting the inspection and the date. In addition, management should review the report, also providing a signature and date. This record will be evaluated for accuracy and completeness during your next inspection by the Radiation Management Unit.


If you have questions about the annual review or inspection process, please call Jennifer Opila at (303) 692-3403.


Licensees and registrants must maintain exposures so that the total effective dose equivalent to individual members of the public from the licensed or registered operation does not exceed 1 milliSievert in a year; and the dose in any unrestricted area from external sources does not exceed 0.02 milliSievert in any one hour. (See RH 4.14 and 4.15 of the Regulations.) Compliance can be demonstrated by surveys and/or calculations. The Division has guidance available for downloading,  How Do I Determine Compliance With Public Dose Requirements pdf file  , to assist in the evaluation of public doses.
