Which method is used to detection and measurement of radiation?

Radiation detectors are devices for detecting and measuring ionizing radiation. Radiation dosimeters are a subset of radiation detectors and are designed to measure the absorbed dose, that is, the amount of energy deposited by radiation in matter and especially in living tissue. There are several methods and equipment used to detect radiation. These are film badges, gas ionization devices, Geiger-Muller counters, radon detectors, personal radiation detectors, fog chambers, and scintillation counters.

As the voltage in the ionization chamber increases beyond V-2, the current increases because electrons moving through the upper electric field acquire enough energy to cause secondary ionization. Therefore, the original ionization is multiplied and a larger pulse is obtained. The α particles are found in the region of the voltage plateau, which produce a large amount of primary ions as shown in Fig (. If the amplitude of the pulse is proportional to the energy of the original ionizing particles, the intensity of the pulse height can be useful in detecting and identifying the nature of the radiation.

These range from large fog chambers to personal portable devices, which is a counter used to detect radiation. Photographic film plates can be used to detect radiation as ionizing particles interact with the film to change the optical density of the film. Radiation can be detected by other means, in addition to ionization of gases, particularly in laboratory environments. 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. For quantitative work, radiation measurement is performed with a scintillation counter, an instrument that counts the intensity of radiation.
