The primary pathway by which radionuclides can
move off the INEEL is through the air and for this reason the air
pathway is the primary focus of monitoring on and around the INEEL.
Samples for particulates and iodine-131 (131I) gas in air were collected
weekly at 16 locations using low-volume air samplers for the duration of
the quarter. Moisture in the atmosphere was sampled at four locations
around the INEEL and analyzed for tritium. Concentrations of airborne
particulates less than 10 micrometers in diameter (PM10) were measured
for comparison with EPA standards at three locations. Air sampling
activities and results for the first quarter, 2002 are discussed below.
A summary of approximate minimum detectable concentrations (MDCs) for
radiological analyses and DOE Derived Concentration Guide (DCG) (DOE
1993) values is provided in Appendix B.
