  • Surface contamination monitoring system and method
    Patent number: 9040932
    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.

  • Body self-shielding background compensation for contamination monitors based on anthropometrics
    Patent number: 8748838
    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.
