The conventional unit rad or the SI unit gray (Gy) are used to measure the radiation dose that an individual has absorbed, or the quantity of energy that radiation has deposited in human tissue.
Using the image sensor of the smartphone, GammaPixTM is an application that can be used on both Android and iPhone devices to identify and quantify ionizing radiation fields.The software determines the local gamma-ray radiation environment by analyzing digital photos captured by a smartphone camera.
[Alpha] radiation is radon. Only beta and gamma radiation may be detected by the Geiger counters above. Thus, the fact that the radon detector is an alpha detector explains why it is so costly. Compared to beta and gamma detectors, alpha detectors are significantly rarer.
While it is not feasible to assess low levels of radon in a residence simply by waving a Geiger counter in the air, having an HVAC system (heating or air conditioning that circulates air through a filter) makes the process very simple.One byproduct of uranium decay is radon.
All that a geiger counter is is a tube filled with gas and two electrodes.It runs in avalanche mode, which means that it doesn't know the energy of the incident photon-it just counts pulses.They cost little.Because the scintillator has a lot larger mass in the sensor, it can absorb more gamma rays and is therefore more sensitive.

While some of the ionization particles from unstable Radon isotopes may be detected by a Geiger counter, its total presence may not be fully detected.
These include solid state detectors, scintillators, and gas-filled detectors.Each is suited for their own distinct duties due to their varied skills and shortcomings.Gas-filled detectors, the original kind of radiation detector, are among the most widely used types.
Known by several names, including Geiger–Müller counter or G-M counter, Geiger counters (/ˈ˥aɪɡər/, GUY-gher) are electrical devices for ionizing radiation detection and measurement.Applications including radiation dosimetry, radiological protection, experimental physics, and the nuclear industry make extensive use of it.
Spectrophotometers and imagers are the two main categories into which gamma-ray detectors fall.In optical astronomy, the first class would normally be referred to as spectrometers or photometers.
