Description
By connection of up to four additional radon chambers (soil gas probe, indoor air sensor) it is possible to measure the radon concentration in different rooms with one radon/thoron monitor. In addition, differential pressure and temperature sensors may complete a sampling system to investigate the radon transportation processes in buildings and facilities.
Another application is the geophysical instrumentation, where water analytics and sampling of soil gases can be integrated. A spectroscopic NaI(Tl) gamma detector and/or gas sensors for carbon monoxide and combustible gases are very helpful for the mining and uranium industry. There is no limit to your ideas.
The radon measurement chamber, based on the principle of high voltage collection, offers high sensitivity at a small internal volume. This is a big advantage for thoron sensitivity and it allows us to use a small pump rate which is often important (soil gas sampling).
The long term contamination by Polonium-210, known from other measurement principals is completely rejected. There is no cross-sensitivity to ambient gamma radiation. Due to its special design, the chamber is not sensitive against variations of the ambient humidity. The commonly used drying equipment for instruments using this principal is not required for the RTM 2200.
We use high-quality silicon radiation detectors inside the chamber to separate the various radon daughter products by alpha spectroscopy.
Quality assurance is a basic concern of every radiation measurement. Therefore, the radon/thoron monitor RTM 2200 saves a complete alpha spectrum for each data record. The spectrum always allows checking the error-free operation of the unit.
All results are presented on a large display with touch buttons. A SD memory card allows collecting a huge amount of data if necessary. Each record will be stamped by the GPS coordinates if the GPS option has been chosen. Data transfer is realized by the USB port and serial interface (RS-232). The RS-232 allows the connection of broadband mobile modems. Optionally, the serial port can be replaced by an integrated wireless network adapter (Net Monitors).
