Are radiation detectors accurate?

Nuclear medicine personnel working with medical isotopes or in facilities that use radiation should monitor their risk of exposure at all times. The instruments are usually portable and highly accurate with an excellent energy response to the dose rate. EcoTestVIP is the best solution for successful people who place great importance on their own safety. It is the only first-class dosimeter in the world.

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. Alpha radiation cannot be detected because it is blocked by the mobile phone case, lens and cover. The second major type of detectors used in radiation detection instruments are scintillation detectors.

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 Although they are designed to detect visible light, they can also detect energies higher levels of ionizing radiation8.These results show that devices can accurately determine the dose rate to which a person is exposed and that the phone is sensitive enough to detect radiation at levels that are significant in a radiological event. Some specific radiation detectors can only protect you from certain radiation and do not provide comprehensive security for you and your environment. The PCE-G28 is a portable handheld electromagnetic field radiation detector or gauss meter that detects electromagnetic fields (EMF) and displays measurement results in MilliGauss (mG) or MicroTesla (µT). 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.

In the event of an emergency, ECOTEST TM search devices will quickly detect and locate a radiation threat. Primarily the purpose of radiation safety personnel, first responders or groups such as customs border inspectors %26, radiation screening has a different set of requirements to reflect the significantly different circumstances under which it is carried out. In addition, as the distance increased, the dose rate decreased and, consequently, the radiation detected by the application decreased. The radiation detection application uses the phone to record the number of times it detects an interaction and that number becomes the dose received by the phone.

To use smartphones as radiation alarms, smartphone radiation responses must be carefully characterized. Advanced image sensors installed in now-ubiquitous smartphones can be used to detect ionizing radiation in addition to visible light. Radiation can be used in a variety of applications, and approximately 23 million workers are occupationally exposed to ionizing radiation worldwide6.
