Accelerator Safety Program

Updated February 21, 2017

OVERVIEW

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)

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.

 

REGISTRATION PROCESS

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.

 

NOTICIFATION

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.)
