| Popis: | 102 Learned from nuclear disaster in Fukushima Daiichi, Japan, potential radiation safety issues have received more attention since then. People always try to know whether their living environment are any radiation contamination but there is no easy way to do. According to the principle of radiation detection, radiation detector can be classified into three types: gas-filled detector, scintillation detector, and solid-state detector. A traditional gas-filled detector is not easy to be manufactured and is more complicated in setting and higher cost than those of a solid-state one. That prevents the gas-filled detector from being pervasive in realistic. In turn, the solid-state detector provides with the advantages of low cost, simple in operation, and relative efficiency comparing to the gas-filled detector, and it is thus selected as the radiation detector of this research. The objective of the thesis is to develop a radiation detection system to be operated on Android-based handheld devices, such as smart phone or tablet. The solid-state detectors are supported and designed by Institute of Nuclear Energy Research. The detector’s output is fed into the microphone jack of a smart phone, and then the developed software processes the signal and counts the number of valid pulses per minute which reflects the intensity of radiation. Measurement of radiation presents real-time results in four different ways: uSv/hr, counts per minute(CPM), instant counts(CNT) and wave. All measured data, in conjunction with the photo taken and the GPS coordinates, can be uploaded to a dedicated server for recording and further analysis. Through massive tests, it proved the applicability of the designed system to various smart phones. |
