What Is a Radiation Monitor?
The type of radiation monitor depends on the nature of the radiation to be measured. For example, the type of radiation monitors that can be used depends on whether the radiation level is high or low or whether the radiation is alpha, gamma, beta, or X-ray.
Commonly used radiation monitors include scintillation radiation meters, GM (Geiger-Müller) tube radiation meters, ionization chamber radiation meters, and personal dosimeters.
Uses of Radiation Monitors
1. Scintillation Radiation Meters
Scintillation radiation meters use scintillators (objects) that emit light in response to X-rays and gamma rays to measure radiation levels. Generally, sodium iodide is used as a scintillator, but cesium iodide is also used.
Scintillation radiation meters cannot detect radiation other than X-rays and gamma rays, but they can detect weak radiation, making them suitable for measuring air radiation dose rates in the general environment. They can also be used to identify where the source of contamination is located by taking advantage of the fact that the measured value fluctuates with changes in distance from the source of contamination.
2. GM (Geiger-Müller) Tube Radiation Detectors
This radiation monitor measures the degree of body surface contamination and is mainly used to measure beta radiation. It can also be used to measure gamma and X-rays and air radiation dose rate, but its accuracy is lower than that of the scintillation type. They are also used to measure the presence of radioactive materials on the clothing and body surfaces of workers, etc., and to analyze nuclides in research experiments.
3. Ionization Chamber Radiation Detectors
Ionization chamber radiation detectors are used to measure the radiation dose rate in the air. Since the ionization chamber type can only detect strong radiation, it can be used in environments with high radiation levels, such as in the manufacture of X-ray equipment such as CT and X-ray machines, in medical facilities where such equipment is used, and in nuclear power plants, rather than in general environments.
4. Personal Dosimeter
It can measure the degree to which the wearer is exposed to radiation over a given period of time.
Principle of Radiation Monitors
Radiation monitors use the interaction between radiation and matter to make measurements. The ionization chamber and GM-tube radiation meters use the ionizing effect between radiation and gas. Ionization is the action of radiation on the nucleus of an atom in a material, causing its electrons to be repelled outward.
The ionization chamber and GM-tube radiation detectors calculate the radiation dose by converting the electric current generated by this ionization into an electrical signal.
Scintillation radiation meters use excitation between materials. Excitation is the process by which radiation imparts energy to the electrons of an atomic nucleus, causing them to be repelled into an outer orbital. In the excitation process, the energy is emitted as light when the scintillator returns to its stable ground state from the excited state, which is a high-energy state within the activated state. The same principle of fluorescence is also used in personal dosimeters.
