Helium-3 detectors

Helium-3 detectors use a special isotope of helium called helium-3 to identify neutrons, which are neutral particles emitted by radioactive materials or nuclear reactions. When a neutron encounters helium-3, it interacts with the nucleus, producing charged particles that create an electrical signal. This process allows the detector to sense the presence of neutrons accurately. Helium-3 detectors are valued for their high sensitivity, reliability, and ability to distinguish neutrons from other radiation, making them essential in nuclear security, scientific research, and radiation monitoring.
