Abstract: A radiation detector system/method that simultaneously detects alpha/beta, beta/gamma, or alpha/beta/gamma radiation within an integrated detector is disclosed. The system incorporates a photomultiplier tube with radiation scintillation materials to detect alpha/beta/gamma radiation. The photomultiplier tube output is then shape amplified and fed through discriminators to detect the individual radiation types. The discriminator outputs are fed to an anti-coincidence and pulse width and timing analysis module that determines whether individual alpha/beta/gamma pulses are valid and should be counted by corresponding alpha/beta/gamma pulse radiation counters. 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.

Abstract: A surface contamination monitoring system/method configured to correct the detected the radioactive net count rate (NCR) value of a whole-body surface contamination monitoring device based on monitored subject height and thickness is disclosed. The system includes a height detection means for determining the height of a monitored subject and a thickness detection means for determining the thickness of at least a portion of the monitored subject. The net count rate (NCR) is corrected based on the determined height and thickness of the monitored subject as applied to site calibration factor data and self-shielding factor data to produce a corrected net count rate (CNR). If the corrected net count rate (CNR) registers above a preset alarm threshold, the monitored subject is considered contaminated and an appropriate alarm is registered.

Abstract: A radiation detector system and method that significantly reduces the cost of conventionally constructed radiation detectors is disclosed. The disclosed system generally comprises an injection molded detector body incorporating plastic material with embedded feed-thrus that are encapsulated within the detector body. This detector body is mated to a detector window assembly using a gasket or other means of sealing to inhibit gas leakage. The mating methodology between the detector body and the detector window assembly is by means of plastic snap-on tabs in these structures that permit semi-permanent mating while also allowing the structures to be easily disassembled for repair and maintenance. The present invention system/method permits a significant hardware cost reduction as compared to conventional prior art radiation detector construction methodologies.

Abstract: A system and method for correcting, based on a monitored subject's height and thickness, the net count rate value of a whole-body surface contamination monitoring device. The device includes a height detection means for determining the height of a subject being monitored, and a thickness detection means for determining the thickness of at least a portion of the body of the subject being monitored. The net count rate is based on site calibration factor data and self-shielding factor data, wherein both types of factor data consider the determined height and thickness.
