Required Training by User Type

The Division of Radiation Safety operates an extensive training program to meet regulatory training mandates and NRC license commitments. The NIH Radiation Safety Program is designed to achieve strict compliance with applicable Federal Regulations, which require training for individuals working in a restricted area associated with radioactive materials or radiation. Under the current NIH broad scope license agreement with the NRC, the Division of Radiation Safety must establish and implement a training program that covers various kinds of workers who may use or be involved with ionizing radiation.

​​

​Registered ​User Types and Required Training

When a person is registered with the Division of Radiation Safety, they are assigned a user type code according to the nature of their involvement with radiation sources at NIH. The kind of radiation safety training required depends on the assigned user type. ​​​

Definitive policies exist for what type of initial and refresher training is required for NIH staff. All personnel (e.g., researchers) working with radioactive materials and all ancillary personnel (e.g. I-131 oral therapy patient care personnel, housekeepers, police/security, firefighters, animal care, maintenance, and Operating Room personnel) whose duties may require them to work in the vicinity of radioactive materials must receive instruction about radiation hazards and appropriate precautions as specified in NRC 10 CFR 19​. NIH training requirements also exist for new or returning radioactive material users. ​​​​
