Currently, the development of an inexpensive, convenient, portable, and digitized device for recording ionizing radiation is very relevant.
The topic of the master's thesis is related to the effective determination of the level of environmental pollution, which directly affects the quality of life. The level of radioactive background is one of the indicators that require constant monitoring. The impact of ionized particles on the human body may appear after a long time, then control may no longer be relevant.
In connection with the discovery of new technologies - appears to improve existing systems, reduce the cost of the device, increase the level of accuracy, and increase the level of speed.
In this project, a device based on a Geiger counter and a signal-processing algorithm for pulse separation and radiation dose calculation was developed. The device registers radiation, and transmits the data to a smartphone, the developed application analyzes the data, calculates the values of doses, and visualizes the information. The developed system determines the accumulated dose and notifies the user if the value of the equivalent dose is exceeded. The improved algorithm of signal processing allows for reducing the time of notification of the user in the event of an increased radiation dose.
