Radiation detection is achieved through the use of a variety of instruments. The most common type of radiation detector is a Geiger-Mueller (GM) tube, also called a Geiger counter. There are several methods and equipment used to detect radiation. These are film badges, gas ionization devices, Geiger-Muller counters, radon detectors, personal radiation detectors, fog chambers and scintillation counters.
Many people, thinking about radiation detection, tend to group them all under the term “Geiger counters”, a misconception heartily encouraged by popular TV shows and movies. While one of the most common types of radiation detectors is called a “Geiger Mueller (G-M)” tube, the general phrase “Geiger counter” is not always the most appropriate. It applies to a very specific type of detector and, in general, to a specific application of that detector. Radiation detection devices are typically classified by the type of detector element employed or by the application involved.
People will refer to the instruments as an ion chamber, a probing meter, a pollution meter, or a Frisker probe. Popular culture has so profoundly subverted the proper use of “Geiger Counter” that the use of the phrase generally does not provide enough information about the device in question. Alpha radiation cannot be detected because it is blocked by the mobile phone case, lens and cover. This error analysis quantitatively shows that the RadioActivityCounter application can effectively function as a radiation detector at high radiation doses; however, at low doses, the application returns a high error percentage as presented in Fig.
These indicate high levels of radiation for some time, while the other detectors indicate levels of radiation at that point. Radiation can be detected by other means, in addition to gas ionization, particularly in laboratory environments. They can be replaced irregularly by using a smartphone app to detect harmful radiation, such as that caused by gamma rays. Photographic film plates can be used to detect radiation as ionizing particles interact with the film to change the optical density of the film.
Various methods and equipment are used to detect radiation, such as film plates, gas ionization devices, Geiger-Muller counters, radon detectors, personal radiation detectors, fog chambers, and scintillation counters. Advanced image sensors installed in smartphones, now ubiquitous, can be used to detect ionizing radiation in addition to visible light. The advantage of using a smartphone application in radiation detection is that it is cheap, easy to operate and accessible, since many people own smartphones. Although they are designed to detect visible light, they can also detect the higher energies of ionizing radiation.
The advantage of using a smartphone app in radiation detection is that it is cheap, easy to operate and accessible, since many people have smartphones. This work aims to inform a detailed investigation of a well-reviewed smartphone application for radiation dosimetry that is available for popular smartphone devices under a calibration protocol that is typically used for commercial calibration of radiation dosimetry detectors. radiation. These range from large fog chambers to personal portable devices, which is a counter used to detect radiation.
Nor should the response of an ionizing radiation detector depend on the angle of impact of the radiation. In addition, as the distance increased, the dose rate decreased and, consequently, the radiation detected by the application decreased. .
