Radiation Safety

The Radiation Safety Office 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.

Dosimeter Application

The primary use of a dosimeter is to provide a record of personnel radiation exposure. Dosimeters are returned every 2 months in order to identify possible problem areas on a continuing basis. Wearing a dosimeter is required for some isotopes and uses, as determined by the CU Radiation Safety Office. You can obtain a dosimeter through our Radiation Safety Office. To get a dosimeter, follow the steps below:

  1. Complete appropriate Radiation Safety Training module on BioRAFT. (Search Course Directory under the Training link)
  2. Fill out the Whole Body Dosimetry Application (fillable PDF) with as much information as possible.
  3. Print out form
  4. Return form to the Radiation Safety Office via email (radsafety@colorado.edu), campus mail (413 UCB) or fax to (303) 492-1322

Security of Radiation

The Radiation Safety Committee (RSC) is committed to the safe use and storage of radioactive materials on campus. All radioactive materials and radiation-producing machines must be secured from unauthorized use or removal. Contact the Radiation Safety Office with questions regarding this requirement.

Laser Safety

The University of Colorado Boulder encourages laboratories using lasers to follow the recommendations in the most current American National Standard for Safe Use of Lasers (ANSI Z136.1-2007). ¬†Copies of the ANSI standard are available at the Engineering Library on campus (the Library restricts use to University affiliates with a 3 day check-out time ‚ÄĒ ask for the Standard at the Information Desk).

A Laser Safety Manual is available for campus laser users, as well as a voluntary training module addressing the safe use of lasers, which can be found on the University BioRAFT page.

In addition, the CU 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:
