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 Reasonable Achievable (ALARA)
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
- admistrative/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.)
