Radiological and Environmental Assessment Section (REAS)

Diffuse NARM Licensing

Diffuse NARM is defined as naturally occurring or accelerator-produced radioactive material that has been concentrated, but not for the purpose of use in commercial, medical, or research activities. The applicable licensing regulations are available at N.J.A.C. 7:28-4. Examples of diffuse NARM would be activation products from particle accelerators, residuals from mineral processing or water treatment facilities. Technologically Enhanced Naturally Occurring Radioactive Materials (TENORM) is a subset of diffuse NARM.

The section also provides technical assistance to the Department for review/oversight of site remediation cases or other investigations which involve radionuclides. Most such cases are managed by Licensed Site Remediation Professionals (LSRP).

Radiologically Contaminated Site Cleanups

Staff of the Bureau of Environmental Radiation provide technical support to the Site Remediation Program on the investigation and remediation of radiologically contaminated sites in New Jersey. The Licensed Site Remediation Professional (LSRP) program applies to these sites with one notable exception - the LSRP cannot approve and implement any work regarding the radionuclide contamination without first obtaining Department approval. Sites contaminated with radioactive materials in New Jersey include former manufacturing facilities, sites that were part of the Manhattan Project (the first nuclear weapons program), and various mineral/mining operations. Regulations, guidance, and a spreadsheet available for download assist LSRPs, consultants and responsible parties in complying with cleanup requirements.
