PORTABLE RADON MONITOR

Model # TBM-IC-RN

FEATURES: DIGITAL READOUT:     6 Digits Rate,     8 Digits Integrate SMALL LIGHTWEIGHT 26 oz. TBM PACKAGE FLAT RESPONSE - FREE AIR ION CHAMBER SEES AXIALLY BELOW 5 KEV GAMMA OR X-RAY FAST RESPONSE WIDE RANGE APPLICATION: Whenever a fast, sensitive Radon Detector is needed, the TBM-IC-RN detects 10 picoCi/l in 5 seconds and detects public release level in less than 10 minutes. This instrument is the latest in a series. The TBM-IC-RN ion chambers are now smaller and lighter and based on newest stable, essentially drift-free electrometer technology.

TBM-IC-RN

DESCRIPTION: The TBM-IC-RN consists of a 2.9" dia x 3.5" long air ion chamber coupled to a stable solid state MOSFET input electrometer with built in A to D converter to read out directly in a nanoCi/liter. Range is 10 picoCi/l to 1 µCi/l. Ion Chamber walls are 180 mg/cm2 graphite lined methacrylate walls and give accurate "air equivalence." Quick change Ion Chamber Shell allows conversion to TBM-IC-Survey Meter.

SPECIFICATIONS:

• Detector: Free Air ion chamber 2.9'' dia x 3.5'' long. Internal volume 300 cc.
• Wall & Cap: Methacrylate, graphite lined 180 mg/cm² walls and 540 mg/cm² cap.

Working Level and Rn-222 Radon Gas vs. Radon Daughters:
 
Option 1: Particulate pre-filter removes much of the Radon daughters from the in-coming air stream but lets the Radon gas pass into the ion chamber for measurement.
 
Option 2: Activated charcoal pre-filter which stops much of the Radon gas is also available.
