Manuals and procedures
Various operations and activities at SLAC generate, or
have the potential to generate, ionizing radiation. SLAC’s
sources of ionizing radiation include:
Note: Some consumer products have naturally-occurring radioactive
elements (thorium welding electrodes, and thorium sand blasting
Soil Density Gauges
registered BEFORE allowed at SLAC
Sand Blasting media
This includes soil density gauges and naturally occurring radioactive material such as thorium welding electrodes and thorium sand blasting media. Complete list is located on the RP website: http://www-group.slac.stanford.edu/esh/rp/restrictions.htm
If any subcontractor or lower tier subcontractor are considering purchasing, or bringing such material onto the SLAC site, they shall notify and receive authorization BEFORE bringing these or similar materials to SLAC National Accelerator Laboratory. Review and authorization is needed prior to bringing these items on site.
For most people at SLAC, these sources of radiation represent a negligible hazard and the resulting risk remains very low. However, for those who work near these sources, the hazard could be significant without appropriate control and mitigation.
Department of Energy and other Federal, State and local government agencies highly regulate and routinely review all aspects of ionizing radiation.
To protect against radiation hazards, and to comply with the applicable regulations, SLAC has implemented a comprehensive radiation protection program.
The goal of SLAC radiation protection program is to keep all exposures to its personnel, visitors, public and environment As Low As Reasonably Achievable (ALARA), and far below the applicable regulatory limits.
Engineering and administrative controls are used to control and mitigate the hazards:
Everyone at SLAC must follow the radiation safety requirements. This includes training and dosimetry.
Wear your dosimeter whenever you are in an area with a sign indicating that a dosimeter is required for entry.
Notify RP promptly if your dosimeter is lost or compromised (i.e. exposed to medical, dental, or airport x-rays).
Return your dosimeter at the end of the wear period or at the end of the project, whichever is sooner.
Contractors who do not return dosimeters will be charged
GERT is the minimum training required for
unescorted access to Controlled Areas and RCA’s
Additional controls required for entry into radiological areas:
High Radiation Area
NOTE: No visitors or escorted personnel are allowed in these areas without prior written approval from RP.
Please be aware
Average power levels must not exceed 5mW
