Serving the NIH Community


​​​​​​​​​​​​​​​​​​​​​​​​​​T​he NIH Radiation ​​Safety Training Program is comprised of a number of courses and many specialized training tailored to the specific needs of certain occupational groups, as well as periodic refresher training for radioactive material users and support personnel who may, occasionally, frequent a restricted area.

The NIH Radiation Safety Program requires that all individuals working with radioactive sources receive entry level radiation safety training as well as periodic refresher training. Note that many of the training items pertain to circumstances and license conditions specific to the NIH; therefore, it may not be assumed that this initial instruction has been adequately covered by prior radiation safety training at another institution. ​​​
