Can you detect radiation?

Human Senses Cannot Detect Radiation. A variety of portable and laboratory instruments are available for detecting and measuring radiation. 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.

Electron capture is where an electron and a proton merge, forming a neutron and releasing an electronic neutrino. Beta decay is less ionizing compared to alpha decay, but has a more penetrating depth and can travel further. Gamma decay is the release of gamma rays, which carry with them the energy of the unstable nucleus of the atom. Gamma rays are the least ionizing of the three types of decay; however, they are the most penetrating and are only stopped by thick lead.

This information is useful for understanding how to detect radiation. One way to detect radiation is to use the ionizing power of these decay structures. Ionization energies interact and excite gas molecules that can allow a current to flow. This current can be read using several meters.

A smartphone camera can turn it into a walking gamma ray detector. Without the need for any additional hardware, you could receive a warning on your phone when you approach potentially harmful levels of gamma radiation. Scientists tested its radiation detection application on four smartphones and concluded that it works well enough to be a useful alert system for first responders. 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.

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. They concluded that phones have the processing power to detect gamma radiation with their built-in cameras and measure levels on the phone. 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 detectors. In addition, as the distance increased, the dose rate decreased and, consequently, the radiation detected by the application decreased.

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. These indicate high levels of radiation for some time, while the other detectors indicate levels of radiation at that point. Photographic film plates can be used to detect radiation as ionizing particles interact with the film to change the optical density of the film. They can be replaced irregularly by using a smartphone app to detect harmful radiation, such as that caused by gamma rays.

Of course, it won't be as sensitive as a normal detector, but it's definitely enough to detect radiation before it reaches deadly levels and is useful enough as a warning system, he says. Complementary metal oxide semiconductor (CMOS) imaging sensors used in smartphone cameras, on the other hand, can detect photons of ionizing radiation, such as high-energy x-rays and gamma rays.8 Alpha radiation cannot be detected because it is blocked by the housing, lens, and the mobile phone 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. Advanced image sensors installed in smartphones, now ubiquitous, can be used to detect ionizing radiation in addition to visible light.

When talking about radiation detection instruments, there are three types of detectors that are most often used, depending on the specific needs of the device. .
