Radiological Environmental Monitoring Program CY-LA-170-301 Revision 9 December 2017 Part II, Offsite Dose Calculation Manual Far field samples are analyzed when near field results are inconsistent with previous measurements and radioactivity is confirmed as having its origin in airborne effluents released from the station, or at the discretion of the ODCM Specialist.
Airborne particulate sample filters shall be analyzed for gross beta radioactivity 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or more after sampling to allow for radon and thorium daughter decay.
If gross beta activity in air particulate samples is greater than 1 O times the yearly mean of control samples, gamma isotopic analysis shall be performed on the individual samples.
Gamma isotopic analysis means the identification and quantification of gamma emitting radionuclides that may be attributable to the effluents from the station.
1-131 analysis means the analytical separation and counting procedure are specific for this radionuclide.
