High pressure ionization chamber gamma radiation monitor

High-pressure ionization chamberGamma radiation monitorUsed for environmental gamma ray dose rate,Widely used in fields such as nuclear facilities, nuclear medicine, industry, and environmental monitoring, it can be used for radiation monitoring in nuclear power plants, radiation protection monitoring in radioactive pharmaceutical enterprises, and monitoring of gamma radiation dose rates in the environment.

• Structural composition: usually composed of a high-pressure ionization chamber detector and electronic circuits. The high-pressure ionization chamber is generally cylindrical or spherical. For example, the core detection unit of our high-pressure ionization chamber gamma monitoring device is a cylindrical ionization chamber filled with 20 atmospheres of argon gas. Electronic circuits include current frequency conversion circuits, MOSFET electrostatic meters, secondary amplification circuits, high and low voltage converters, and readout circuits.

Ionization chamber detector

A detector made using the ionization effect of nuclear radiation in gas. When the radiation passes through the detection gas, it produces ionization effects that ionize or excite gas molecules. During ionization, a portion of the energy obtained by electrons outside the nucleus is sufficient to overcome the confinement of atoms and generate a large number of ion pairs along the path of incident charged particles- Electrons and cations.
