LASALLE Revision 1.9 March 1997 Table 11 1 (Cont'd)

Radiological Environmental Monitoring Program Far field samples are analyzed when near field results are inconsistent with previous measurements and radioactivity is confirmed as having its origin in airbome effluents refeased from the station. or at the discretion of the Radiaton Protechon Director.

Airbome 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 thoron daughter decay. If gross beta activity in air particulate samples is greater than 10 times the yearly mean of control samples, gamma isotopic analysis shall be performed on the individual samples.

3 Gamma isopic analysis means the idenbfication and quantification of gamma emitting radionuclides that may be attributable to the effluents from the station.

l-131 analysis means the analytical separation and counting procedure are specific for this radionuclide.
