Handheld Radionuclide Identification Devices RIDs

Handheld radionuclide identification devices, commonly referred to as RIDs, are portable spectroscopic instruments used by security, customs, and military personnel to detect ionizing radiation and identify the specific radioactive isotope responsible for the detected emission in real time without laboratory analysis. RIDs distinguish themselves from basic radiation survey meters by incorporating a gamma-ray spectroscopy capability that resolves the energy spectrum of incoming photons and matches the observed spectral peaks against an onboard isotope library to produce a named identification result with associated confidence level and threat classification.

Scintillation detector materials used in RIDs include sodium iodide, cesium iodide, and lanthanum bromide crystals, with lanthanum bromide preferred in professional-grade instruments due to its superior energy resolution compared to NaI without requiring the cryogenic cooling needed by high-purity germanium detectors. Energy resolution in LaBr3-based RIDs falls between 2.5% and 3.5% at 662 keV, enabling discrimination between isotopes with closely spaced gamma emission lines that NaI-based systems cannot reliably separate.
