Radiological Air Sample Quarterly Composites (ARCHIVED)

Per Health and Safety Code 114755 which mandates that "The department shall monitor radioactive materials in the environment", air sampling stations have been placed in or near major population centers with the potential for significant radiological activity. The data presented in this table are for quarterly aggregates of sampling media per site.

Dose per quarter is reported in millirem Total Effective Dose Equivalent (TEDE); all other values are radiological activity concentrations reported in units of picoCuries per cubic meter. Any positive result less than the minimum detectable activity is attributable to statistical measurement noise, and results are reported even in the case of non-detection. Beryllium-7 and Potassium-40 are naturally occurring radionuclides.
