DetectionNew radiation detector unveiled, does not rely on helium-3

Princeton Security Technologies, Inc. appears to have a solution to the quickly dwindling helium-3 stockpiles. On Tuesday the companyannounced that it had developed and delivered the first commercially available nuclear materials detector that does not rely on helium-3.

Demand for radiation detectors has surged as a result of increased efforts to stop nuclear proliferation and terrorism, but production of helium-3, a critical element in nuclear detection technology, has not kept pace and existing stockpiles are quickly dwindling. In response to these shortages, DHS has actively sought to investigate alternatives and explore technologies to recycle helium-3 and extend current supplies.

Instead of helium-3, Princeton Security Technologies’ detector uses sodium iodide for gamma detection and Lithium-6 for neutron monitoring.

“The new lithium detector configuration now provides a viable, cost effective alternative for our government customers requiring Neutron detection,” said Alex Palm, the company’s vice president of marketing.

Neutron monitoring has been proven as an effective way to detect terrorists or other malicious actors who seek to obtain radioactive materials or use them in a dirty bomb attack. The company has already delivered its new radiation monitors to be used in hospitals and other security surveillance applications.

Princeton Security Technologies Inc. is part of Princeton Gamma-Tech Instruments, Inc. (PGT), which develops X-ray and Gamma-ray Detectors, Spectroscopy systems, Radiation Detection Area Monitors and Radioactive Radioisotope Identifier products.
