HOME-MADE ALPHA-TRACK DETECTOR FOR RADIOACTIVE GAS: RADON

Reference [1] gives the information that in Romania, the maximum allowed radiation concentration of the natural radon background is of 300 Bq/m(3). According to CNCAN values, the average concentration national level is of 145 Bq/m(3), and in Bucharest, it reaches 202 Bq/m3. There are several places in the country where this level exceeds the natural level. These are the areas where there are radioactive ore deposits, former ones. Radon has been declared a carcinogenic factor and takes second place in the worldwide ranking top as a trigger for lung cancer, immediately after tobacco. To monitor the level of Radon that you have at home/workplace or any other closed spaces, you need to have adequate equipment to do it. The market nowadays offers you a large perspective of devices that can be used (passive or active detectors), but this paper aims to make possible, or at least to make us use our creativity to make a "Home-made non-expensive Radon detector", using cheap things around us: like a webcam, aluminum foil (used to cover food), duct tape.
