Helium-3 for national security

Helium-3 plays a crucial role in national security and border protection through its application in advanced detection systems. In border security, helium-3 is utilized in neutron detectors, which are essential for identifying nuclear and radiological materials. These detectors are highly sensitive and can detect even minute quantities of radioactive substances, making them invaluable for scanning cargo, vehicles, and luggage at ports of entry and border crossings. The unique properties of helium-3 allow for the creation of efficient and reliable radiation portal monitors, which are deployed at strategic checkpoints to prevent the smuggling of nuclear materials. In the broader context of national security, helium-3-based detectors are used in a variety of settings, from airports to seaports, to safeguard against nuclear terrorism and the illicit transportation of radioactive materials. The gas is also employed in certain types of handheld radiation detectors used by security personnel for more targeted inspections. Additionally, helium-3 finds applications in nuclear safeguard systems, helping to monitor and verify compliance with international nuclear non-proliferation agreements.
