General Radiation Management Information

An overview of the Rocky Mountain Low-Level Radioactive Waste Compact is provided by the Rocky Mountain Low-Level Radioactive Waste Board at www.rmllwb.us.



Additional information about radiation in general can be found at the Radiation and Health Physics Internet site at the University of Michigan.



The radiation emergencies or incidents can be reported to the Radiation Program emergency cell phone at 303-877-9757 24 hours per day, 7 days per week. 



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. 




The Laboratory Services Division of the Colorado Department of Public Health and Environment offers radiochemistry testing for a fee.



Naturally occurring radioactive materials (NORM) include radionuclides that have been in the rocks and minerals of the earth's crust since it was created. They can also be produced by interactions between atoms in the atmosphere and cosmic rays.


Technologically enhanced naturally occurring radioacitve materials (TENORM) is produced when activities like uranium mining or sewage sludge treatment concentrate radioactive materials that occur naturally in ores, soils, water or other natural materials.


Information about NORM and TENORM and why they are of concern is provided by US EPA at www.epa.gov/radiation/tenorm/ and on the TENORM Page at http://www.tenorm.com


The Division offers several resources to help you understand the regulations and how they apply to you.  We have a wide array of guidance and policy documents available online 24 hours a day, including summaries of notifications, certifications, registrations and permits as they apply to our various programs.  Our Customer Technical Assistance line is available 8 am - noon, Monday through Friday to answer questions about the regulations and to provide general regulatory interpretations. In addition, our technical staff are available to provide site-specific answers and interpretations.  If you generate smaller quantities of hazardous waste, you may want to take advantage of our onsite Generator Assistance Program where one of our hazardous waste inspectors provides guidance and tips for you to get into and stay in compliance with the regulations during a non-enforcement site visit.  Finally, the Division offers workshops and other trainings throughout the year designed to clarify the regulations and provide an open forum for questions.

Learning Opportunities and Assistance


The Division maintains summaries of permits, notifications, registrations and certifications required by our regulations.  These summaries include information on who needs one, the process to get one and associated fees, among other things.


Permits, Notifications, Registrations and Certifications


To determine if a particular property has or had environmental contamination that the Division has been made aware of, or to review inspection and enforcement reports, you can make a Colorado Open Records Act (CORA) request to review public files associated with the property's address.  The Division will review your request to determine if we have any files on that address and if so, set up an appointment with you to review the files.  If you wish to review files for another division (Air, Water, etc.), you must contact each division individually.


Records Review


Hazardous Waste


The Division posts quarterly inspection and enforcement reports online listing hazardous waste facilities that have been inspected in the past year.  For more complete information regarding the compliance history of a hazardous waste site or facility, visit U.S. EPA's Enforcement and Compliance History Online (ECHO) website at www.epa.gov/echo/ .  This site contains information on hazardous waste facilities in Colorado and other states.
