Clinical Radiation Safety

1. Radiation Safety Training

All individuals working with (or in the vicinity of) radioactive materials or radiation-producing equipment will receive clinical radiation safety instruction before assuming their duties.  Additionally, refresher training will be provided annually and whenever there is a significant change in duties, regulations, terms of the license / permit, or type of radioactive material or therapy device used.  The training programs are developed and presented by the Columbia University Department of Environmental Health and Safety in both live and on-line formats.

Clinical Radiation Safety Training Schedule

Clinical radiation safety refresher training is required annually.

  • If you have been assigned a UNI (CU email) you can take the refresher training in Rascal (course code: TC5400).

2. Dosimetry


ALARA is an acronym for "As Low As Reasonably Achievable."  It means making every reasonable effort to maintain exposures to ionizing radiation as far below the dose limits as practical. 

Details of the ALARA Program may be found in the Radiation Safety Manual.

4. Working with Radiation

The Radiation Safety Manual. includes the policies and procedures of the Radiation Safety Program that govern all work involving the use of radionuclides, radiation–generating equipment and other sources of ionizing radiation.
