Nuclear medicine personnel working with medical isotopes or in facilities that use radiation should always monitor their risk of exposure. To do this, they rely on a variety of instruments, the most common being Geiger-Mueller (GM) tubes, also known as Geiger counters. Alpha radiation, however, cannot be detected by these instruments. Scintillation detectors are the second major type of radiation detectors used in radiation detection instruments.
Complementary metal oxide semiconductor (CMOS) imaging sensors, which are used in smartphone cameras, can detect photons of ionizing radiation such as high-energy x-rays and gamma rays. In the event of an emergency, ECOTEST TM search devices can quickly detect and locate a radiation threat. Radiation screening has different requirements to reflect the significantly different circumstances under which it is carried out. Smartphone applications can be used to detect radiation at levels that are significant in a radiological event.
However, 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). To use smartphones as radiation alarms, their 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.
Approximately 23 million workers are occupationally exposed to ionizing radiation worldwide6. 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. 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 and has an excellent energy response to the dose rate. The application uses the phone to record the number of times it detects an interaction and that number becomes the dose received by the phone.
As the distance increases, the dose rate decreases and, consequently, the radiation detected by the application decreases.
