Abstract

An intelligent apparatus for measuring very low concentrations of radon in air is presented in this paper. It is composed of a special ionization chamber and an analogue/digital processing unit based on a microcontroller. Besides radon detection, this detector is capable of emitting an alarm signal (in case of high radon concentrations) and of transmitting the measurement data to a remote location along with the geographic position of the detector through a GPS/GPRS modem. Because of the synchronous operation (based on the GPS clock) the detector can work in a network covering a large geological fault, displaying measured data locally or over the Internet. With a simple firmware update the detector can also be used with other ionizing particles.
