Purpose: All work involving the use of radiation generating devices and equipment must first be approved by the University Radiological Protection Committee. This includes electron microscopes.

Who should complete this permit: The Research X-Ray Permit Application is filled out by the person who will be responsible for oversight of the use of radiation generating equipment in the department/lab and meets the requirements of ERM.EHS.RS 114 Radioactive Materials and X-Ray Research Permit Holder Requirements and Qualifications.

How to complete this permit: 

1. Permit holders should review, print out and retain a copy of ERM.EHS.RS 118 Research Radioactive Materials, X-ray and Laser Permit Holder Responsibilities.
2. Submit: 
   • Permit Holder’s most recent CV or resume demonstrating radiation generating equipment experience. Submission of a Research Permit Holder Radiological Training Record may be used in substitution to demonstrate previous experience and qualifications.  
   • Research Personnel Radiological Authorization Request for each faculty member or student (other than the permit holder) working with x-ray generating devices. Each form is to be signed by the user and permit holder.
   • Completion of radiation safety training SBRS20 for the permit holder, staff, and students.
   • Diagram/map of all radiation generating equipment locations to be used for radiation generating research. Include locations of radiation device storage, waste storage (if applicable), areas of use, accelerators, etc. Include windows and door locations in each space.  
   • The Research X-Ray Permit Application, completed in its entirety.
3.  Approval process:
   • University Radiation Safety Committee (UPRC) members vote to approve the permit.
   • The determination of satisfactory knowledge is at the discretion of the URPC.
   • Approved permit holders receive notification of decision once the URPC process is complete.

Expiration/amendments: X-ray permits are valid for five years from the approval date. Any amendments to permits must formally be submitted to radiation safety by email and approved by the appropriate University Radiation Protection Committee before the changes can occur. Amendments DO NOT reset permit expiration dates and thus permits must be renewed prior to expiration date associated with permit application approval date. Amendments include:

• Request to add, move or remove equipment.
• Changes in research protocol involving radiation.
• Changes in space (new, temporary relocation, removal).

New users must receive authorization from the Radiation Safety Officer prior to beginning work with x-ray generating equipment. Complete the following steps to request authorization for a new user:

1. Contact the Environmental Health & Safety Front Office at (631) 632-6410 or radiationsafety@stonybrook.edu to request applicable training registration.
2. Complete the assigned trainings in the Learning Management System (LMS).
3. After completing the assigned training, the new user will fill out the Research Personnel Radiological Authorization Request with the appropriate information and signatures.
   • • Please also visit the dosimeter page if working with ionizing radiation to see if ordering a new dosimeter is applicable for the candidate.
4. After the Research Personnel Radiological Authorization Request has been completed and certified by the Candidate and the Permit Holder, the form must be emailed to radiationsafety@stonybrook.edu for review by the Radiation Safety Officer.
5. Users will be informed via email when the Research Personnel Radiological Authorization Request has been approved.

Medical x-ray generating devices are subject to additional regulations beyond duties performed by Radiation Safety. Please contact Medical Physics at Stony Brook University Hospital for additional information about Medical x-ray generating devices.
