Radiological Materials Licensing

About

Health and Mental Hygiene, Department of City
The NYC Department of Health and Mental Hygiene (DOHMH) is the agency that regulates the possession and use of radioactive material in New York City on behalf of the United States Nuclear Regulatory Commission. The DOHMH Office of Radiological Health is responsible for the inspection and licensing of materials for medical, academic and research uses within the City. The possession and use of these materials require rigorous licensing reviews. These 6 types of licenses authorize possession and use of certain radioactive materials for medical, academic and research use by individuals specifically named or otherwise designated in the license.

 

They are:
Type 91-Limited scope medical (except teletherapy): authorizes use of radioactive materials or the radiation that comes from them for specified uses on humans. These licenses may also authorize use of materials in non-human applications by qualified personnel.
Type 92-Limited scope teletherapy license: authorizes use of cobalt-60 in teletherapy machines for treatment of humans. This license does not authorize any other activities or materials, with exception of depleted uranium used as shielding in teletherapy machines.
Type 93-Limited scope gamma knife license: authorizes use of cobalt-60 in gamma knife machines for treatment of humans. This license does not authorize any other activities or materials, with exception of depleted uranium used as shielding in gamma knife machines.
Type 52-Limited scope non-human use license: authorizes research and development, clinical testing activities, or use of analytical equipment where radioactive materials or resulting radiation are used in other than human applications.
Type 75-Human use broad scope license: authorizes a variety of activities in or on humans under a general authorization, and may also authorize use of materials in non-human applications.
Type 74-Non-human use broad scope license: authorizes variety of activities under general authorization which do not involve application of radioactive materials or resulting radiation to humans.

If a licensee considers making a change that would affect licensed operation or facility (including but not limited to changes ordered pursuant to NYC Code), that will cause the information on file with DOHMH to be out-of-date, the licensee must request and receive an amendment, before making the change.

The license is issued for 5 years.
