Requesting Exposure Monitoring Records

Exposure monitoring records for employers or other agencies outside of the NIH can be obtained by providing a signed, written request to the address below. The request should include your full name, date of birth and/or NIH ID, and dates of employment at NIH. ​​

Regulation Limits and Exposure Trigger Levels

Occupational radiation exposures are subject to regulatory limits set by the Nuclear Regulatory Commission (NRC) or Occupational Safety and Health Administration (OSHA)​ based on the type of radioactive material or devices used.  Staff who work in both arenas are held to both sets of limits by DS policy. The NRC has jurisdiction over all occupational exposure if any of the exposure is the result of NRC-regulated activities. 

Notwithstanding these regulatory limits, the NIH Radiation Safety Program works to minimize occupational exposures through the NIH ALARA program​.

Trigger Level Guidelines

To ensure occupational worker safety based on regulatory limits, investigations are performed when occupational exposures from external or internal monitoring results exceed an established trigger level, as noted in the table below. 

Investigations may be formal or informal in nature, depending on the circumstances surrounding the exposure in question. In most cases, exposure values may not be unusual for the work performed.  The DS investigation results are provided to the individual worker.
