Contact the EHS Radiation Protection Services (RPS) Team prior to:

  1. Entering into the system;
  2. Performing any work on the exhaust system (maintenance, repairs, change of the filters, etc.);
  3. Disposing filters in order for RPS to confirm the proper disposal.

The RPS Team will conduct a radiation safety assessment, contamination survey as applicable, and communicate the recommendations to the worker, the supervisor, and/or the project manager.
