    Applying for a DOHMH License for Therapeutic Radiation units does not satisfy regulatory requirements of other City, State and Federal Agencies. It is the business owner's responsibility to meet all other requirements. Failure to comply with all relevant regulations may result in the suspension of DOHMH permits until proof of compliance is provided.

    To view rules for Certified Registration or Therapeutic Radioactive devices, go to and select Article 175.

Or, if exempt, a copy of Form CE-200 stamped by the Worker's Compensation Board with the New York State-assigned Exemption Certificate Number.
