LND, Inc. has been awarded a patent for an enhanced sensitivity neutron detection module (NDM) that uses boron trifluoride as the detection medium. The NDM achieves equivalent sensitivities to Helium-3 systems of the same physical dimensions, making it an ideal drop-in replacement for Helium-3 systems already deployed in the field. The NDM incorporates a number of safety features, including a BF3 adsorbent, and an ambient fill pressure. In fact, as designed and built, the NDM ships by passenger or cargo aircraft as “not restricted” according IATA Special Provision A190.
