measurements/data are paramount. A branch of the RadWatch activities, the
Near-Realtime Air Monitor (RAM) is crucial to public outreach efforts and serves
the dual purpose of providing high resolution spectroscopy data to analyze temporal
and meteorological inputs on variations in the natural radioactive background.
2 Near-Realtime Air Monitor Detection Scheme
The air monitor that we have constructed forces 21SCFM of air through a 4″
diameter HEPA filter which is continuously assayed by a high resolution gamma
spectrometer (HPGe). The FPAE-102 filter collects 99.99% DOP 0.3 lm particles.
The mechanically cooled, n-type HPGe detector has superior energy resolution and
efficiency, even at *10 keV energies. The detector is sensitive in the 3–3000 keV
energy range. Spectra are reported every hour to the public to promote transparency
(Figs. 1 and 2).
