| 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. 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.
- Readout: LCD: 6 Digits Rate; 8 Digits Integrate.
- Indicator Lamp:
Green LED 10 pulses/sec per mR/h.
Red Over-range Indicator.
- Range:
Rate 6 digit 10 picoCi/liter to 1 µCi/liter in a single
range.
Integrate 8 digits 1 picoCi/liter* to 100,000 pCi/liter in a
single range.
*less than 1 minute Indicator.
Note: TBM-IC-RN in Integrate Mode has no timer.
User must provide clock or stopwatch.

- Air Flow: Passive Diffusion or lightweight Battery powered
pump.
- Weight: 26 oz. complete with batteries. Optional pump
is 2 lbs.
- Options: Readout in Si units: Bq/m3.
- Optional Pump: Flow Rate: 4 SCFH. Batteries: 2 AA Batteries.
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.
