3.0  Air Sampling

The primary pathway by which radionuclides can move off-site is through the air and is the primary focus of monitoring on and around the INEEL.  Particulates and iodine-131 (131I) in air were measured weekly at 16 locations using low-volume air samplers for the duration of the quarter.  Moisture in the atmosphere is sampled at four locations around the INEEL and analyzed for tritium.  Concentrations of EPA size-targeted particulates in air are measured using samplers that collect particulates less than 10 microns (PM10) at three locations.  Air sampling activities and results for the third quarter, 2001 are discussed below.
