F:r field samples are analysed when near field results are inconsistent with previous measurements cnd radioactivity is confirmed as having its origin in airborne effluents released from the station, or ct the discretion of the Emergency Planning Supervisor.

• A gamma isotopic analysis shall be performed whenever the gross beta concentration in a sample exceeds by five times (5m) the average concentration of the preceding calender quarter for the sample location.
