Measures all gammas, including low energy gammas and X-rays
Detects axially below 5 keV Gamma / X-ray
Features 8 digit digital display for rate and integration
Wide range: 0.01 mR/hr to 1 R/hr
Flat response free air ion chamber
The TBM-IC-LR Ion Chamber is a fast response, sensitive portable radiation detector for all gammas including low energy. This Ion Chamber features stable, mostly drift-free electrometer technology.
A 5'' dia x 7.5'' long air ion chamber is coupled to a stable solid state MOSFET input electrometer.
The built in A to D converter reads out directly in mR/h or mR.
Rate Range is 0.01 mR/h to 1 R/h in a single range.
Dose Range is 0.05 μR – 100,000 μR in a single range.
430 mg/cm2 graphite lined methacrylate walls provides for accurate ``air equivalent'' response.
Thin (0.5 mg/cm2) Mylar window allows high sensitivity readings for:
-Alpha & Low Energy Betas such as C14
-Low Energy Gammas & X-Rays
-Higher Energy Betas & Gammas
