The Radiation Protection Program provides staff, researchers, students and visitors with a safe accelerator use environment and conforms to the requirements set forth by the Commonwealth of Massachusetts Regulations 105 CMR 121.700 - Radiation Safety Requirements for Particle Accelerators.
The following list provides an overview of the requirements for particle accelerators:
- Registration with the Radiation Protection Office
- Completion of accelerator readiness review (for new installations or major changes)
- Quarterly interlock testing (if an interlock system is required)
- Access controls and irradiation procedures
- Appropriate required radiation safety signage
- All required training for personnel prior to use
- Work is performed using the principles of keeping radiation exposure As Low As Reasonably Achievable (ALARA)
Accelerator Safety Program
The MIT Accelerator Safety Program was established to provide a safe environment for staff, researchers, students and visitors working with and/or around particle accelerators. Any particle accelerator should be registered with RPP. Generally, a machine accelerating particles in excess of 1 MeV is considered a particle accelerator; however, in some cases low energy accelerators (DT & DD neutron generators) also require registration.
Radiation Protection maintains registration of all particle accelerators on and off campus. These registrations contain at minimum the following:
- Personnel information (PI and operators)
- Accelerator capabilities and properties
- Radiation surveys and instrumentation
- Engineering controls (interlocks, emergency off)
- Procedures for interlock search and emergency off situations
- Administrative/operational procedures
- Ancillary hazards
Inform your DLC RPP Officer of any new accelerator or changes to an existing registration.
Radiation Protection must be notified immediately if the following occur:
- Unexpected radiation levels are measured
- Unexpected exposure to radiation occurs
- Malfunction of safety mechanism occurs (interlock, radiation detector, emergency stop, etc.)
