PINS Overview
The Portable Isotopic Nuclear Spectroscopy (PINS) Chemical Identification System identifies dangerous compounds and mixtures non-destructively. The test object need not be opened or touched, providing significant safety benefits. As shown, PINS probes a test object with neutrons that excite the atomic nuclei within, causing the excited nuclei to produce gamma rays. The energy intensity pattern or spectrum of these gamma rays is unique for each chemical element, and by analyzing the gamma-ray spectrum, the PINS software identifies the chemical elements inside the test object and determines if the object contains a chemical warfare agent, a fill (such as sand), or a smoke generating chemical.
