Overview

The spherical neutron dose rate meter (Rem meter) is widely used for detecting neutron dose rates in nuclear power plants, nuclear power plants, research-oriented nuclear reactors, accelerators, and neutron source operations. It can also be used in various levels of environmental protection bureaus, disease control centers, petroleum logging, etc.

Product Details

Spherical neutron dose rate meter (Rem meter)It is an instrument used to measure neutron radiation dose rate, widely used in the nuclear field and radiation protection related scenarios.

Spherical neutron dose rate meter (Rem meter)structural characteristics

A spherical neutron dose rate meter generally consists of a spherical probe and a main unit.

Probe: Using He-3 proportional counting tube and polyethylene moderator, the sensor pressure is 8 times atmospheric pressure, and the spherical structure helps to obtain good angular response.

Host: It is usually equipped with a liquid crystal display screen, such as a 3.2-inch color LCD, which can display real-time dose rate, cumulative dose and other information. It also has communication interfaces, such as USB, RS-485, etc., which can be connected to the upper computer.

Application field

In the field of nuclear facilities: used for neutron dose rate detection in places such as nuclear power plants, nuclear power plants, research-oriented nuclear reactors, accelerators, and neutron source operations.
Environmental monitoring: Environmental protection departments at all levels, disease control centers, and other departments can be used for environmental radiation monitoring, as well as detecting neutron radiation dose in emergency response.
Petroleum exploration: used in petroleum logging and other operations to detect neutrons and obtain geological information.
Security inspection: can be used for nuclear and radiation anti radiation work in customs, ports, border defense, etc., to prevent illegal transportation of radioactive materials and terrorist attacks by radioactive materials.

technical indicators

measurement rangeThe real-time dose rate is generally between 0.01 μ Sv/h and 99.99 mSv/h or higher, and the cumulative dose can reach 0.01 μ Sv to 9999 mSv.
energy rangeThe common energy range is 0.025eV to 15MeV, which can effectively detect neutron rays in the ultra wide energy range.
sensitivityFor the 252Cf source, the sensitivity can reach 2.83CPS/(nSv/h).
Angular responseThe excellent spherical geometric structure and relative position of the counting tube result in a 4 π angle response deviation of less than ± 10% for the instrument.
