The Radiation Safety Unit supports all safety in research involving radioactive materials and radiation-generating machines on the CU Boulder and Colorado Springs campuses. We provide resources, training, and various required safety programs to help you conduct your research and minimize any danger or health hazards in the process.
The University of Colorado has been granted a license for the use of radioactive materials and radiation-generating machines in research. This license has been granted by the Colorado Department of Public Health & Environment (CDPHE) under an agreement with the Nuclear Regulatory Commission, and it calls for compliance with applicable federal and state laws. We work to maintain the health and safety of all radiation-workers at CU Boulder.
Engaging in services and programs set up by our unit will ensure utmost safety while using radiation in your laboratory.
- Basic Radiation Safety Training
- Refresher Training for unsealed sources (radioisotope)
- Sealed Sources Training
- X-Ray Machine Users
In addition to training, you can use our library of resources to stay on top of safety and compliance. You’ll find helpful reference material here including the Radiation Safety Handbook.
The primary use of a dosimeter is to provide a record of personnel radiation exposure. Dosimeters must be returned to us every 2 months so we can identify possible problem areas on a continuing basis. Wearing a dosimeter is required for some isotopes and uses. You can obtain one through our Radiation Safety Unit. To get a dosimeter, follow the steps below:
- Print this Whole Body Dosimetry Application PDF out
- Fill the form in thoroughly
- Return it to the Radiation Safety Unit via campus mail (413 UCB) or via fax to (303) 492-1322
The University of Colorado Boulder does not currently have a Laser Safety Program, but encourages laboratories using lasers to follow current American National Standard for Safe Use of Lasers (ANSI Z136). Please contact us with any questions regarding Laser Safety. The Radiation Safety Office does have limited copies of ANSI Z136.1-2007 available for check-out and review. The Engineering Library on campus also has copies available (the Library restricts use to University affiliates and check-out time is 3 days—ask for the Standard at the Information Desk).
In the meantime, the Radiation Safety Office is collecting information on Class 3b and 4 lasers used on campus. If a class 3b or 4 laser is used as part of your research here at the University, please complete the online Laser Registration Form.
Laser Safety signs and protective goggles/equipment are the responsibility of the laboratory using a Class 3B or 4 laser. These items may be purchased from several vendors, including:
Security of Radioactive Materials
The Radiation Safety Committee (RSC) is committed to the safe use and storage of radioactive materials on campus. Please see the June, 2014 memo from the RSC for laboratory security suggestions and requirements. Contact the Radiation Safety Office with any questions.
