In Connecticut, there are thousands of facilities that use x-ray devices for diagnostic and therapeutic purposes.

The DEEP conducts a registration and inspection program of medical x-ray machines to ensure that:

  1. Exposure to the general public and employees are at safe levels.
  2. The facilities are in compliance with Connecticut's regulations.
  3. Exposure is kept as low as reasonably achievable while delivering the lowest practicable patient dose with the highest possible image quality.

All facilities must register their diagnostic and therapeutic x-ray devices prior to use and biennially thereafter in the month of April in the even numbered years or when there is a change in number or location of the devices. There is a registration fee of $190.00 per x-ray device.

The CTDEEP has revised the Medical X-Ray Registration application process to improve the quality and completeness of this Registration Program. In addition to other revisions listed below, the title of the Registration Form has been changed to Diagnostic and Therapeutic X-Ray Device Registration.

Preparation and Submittal of the Registration Form:

Coming Spring 2015! {Link to EZ File}

The Radiation Division is proud to announce their new on-line Portal system (ezFile) for submitting your Diagnostic and Therapeutic X-Ray Registration.

Stay tuned for details on how to access ezFile and complete your on-line registration. We will notify you as soon as the system is available for your use and encourage you to submit your applications via the ezFile system. Refer to, for details on when the ezFile system will be available and how to access ezFile and complete your registration.

Should you have any questions or if you would like additional information, please contact the Radiation Division at 860-424-3029.

We encourage you to use the new ezFile application process.  However, if you do not have access to a computer, you may still submit a paper based application by following the procedure outlined below:

  • Download the revised Registration Form and Instructions:
  • Be sure to enter your existing facility number onto the Form (Note: the Facility Number can  be found on the bottom of your current Certification of Registration/Use).
  • Submit the completed Registration Form and Fee to: Central Permit Processing Unit, Department of Energy and Environmental Protection, 79 Elm Street, Hartford, CT 06106-5127

Revisions to the Registration Process:

  • Pre-filled registration forms will no longer be sent to registered facilities. Effective March 2010, facilities will need to download a registration form and instructions from the DEEP website.
  • Pending a complete (i.e., full compliance) Registration, Registrants shall be issued a Certificate of Use.
  • Future registration notices will be sent electronically, not via hard copy. Therefore, it is imperative that registrants provide an accurate Registrant E-mail Address (see Part II of the Form) when completing the Registration Form.

Be advised - you cannot possess, store or use any X-Ray devices before registering. Failure to submit a timely renewal registration shall result in non-compliance with Connecticut General Statute 22a-150 (which requires the Registration of X-Ray Devices) and may result in an enforcement action being taken by the DEEP.
