Radiation detector system and method

摘要

A radiation detector system/method (0300) that simultaneously detects alpha/beta, beta/gamma, or alpha/beta/gamma radiation within an integrated detector is disclosed. The system incorporates a photomultiplier tube (0302) with radiation scintillation materials (0301) to detect alpha/beta/gamma radiation. The photomultiplier tube (0302) output is then shape amplified (0303) and fed through discriminators (0304) to detect the individual radiation types. The discriminator outputs are fed to an anti-coincidence and pulse width and timing analysis module (0305) that determines whether individual alpha/beta/gamma pulses are valid and should be counted by corresponding alpha/beta/gamma pulse radiation counters (0306). The system may include a radiation detection method to affect alpha/beta/gamma radiation detection in a variety of contexts. The system/method may be implemented in a variety of applications, including but not limited to whole body radiation contamination detectors, laundry radiation scanners, tool/article radiation detectors, and the like.
