ABSTRACT

This paper presents the results of studies of the characteristics of alpha particles detector like TGEM ('Thick' Gas Electron Multiplier) working in an open air environment. The main advantages of these devices are simplicity, low cost, and high sensitivity to the different kinds of irradiation. One of the possible applications of these new wireless gas detectors is alpha particle or radon background monitors, which can serve also as a dosimeter or as a smoke detector in houses. This detector is able to measure the trace of alpha particles with efficiency close to 100% operating in open air in the avalanche mode at high gas gain (up 10 4 ). The tests were carried out in duty of three summer months. It should be noted that the stability of the results is high enough despite the wide range of temperature and humidity during of testing.
