As part of legal requirements and the SLAC best management practice, the Radiological Environmental Protection (REP) Group of the RP Department has set up active and passive radiation monitoring systems that either continuously or periodically measure the potential radiation and radioactivity that may be released to the public and environment (water and air) due to SLAC operations.

The monitoring results are summarized in the annual report, ASER.

38 environmental dosimeters (Luxel dosimeters from Landauer, Inc.), as well as seven active Perimeter Monitoring Systems (PMSs), are located around strategic SLAC site boundary locations to continuously monitor the potential doses to the public.

The doses from radioactive air release are too small to be measured. Instead, conservative dose estimations are made based on analytic calculations using certified codes and methods.

All releases of industrial waste water into sewer, the storm water discharges, as well as the groundwater wells are monitored by performing sampling and radioactivity measurements.

MEI is stands for Maximum Exposed Individual, a term required by law to be used to describe a hypothetical member of the public outside of the SLAC's site boundary who receives the maximum doses from SLAC operations. This serves as a conservative, maximum estimation of dose to the general public
