Abstract: A system for surveying a surface (2) to measure a physical or chemical property associated with the surface. The system includes a handheld probe (4) measuring a physical or chemical property at locations over a surface (2). The video camera (12) captures video data of a user (6) using the handheld probe (4) to survey the surface. The depth sensing device (14) measures the distance to the handheld probe (4). Processing circuitry identifies the handheld probe from the video data and determines the position of the handheld probe (4) relative to the surface (2). A data recorder and/or a data transmitter records and/or transmits data representative of the physical or chemical property measured by the handheld probe (4) and data representative of the associated position of the handheld probe, when the handheld probe (4) is determined to be less than a threshold distance from the surface (2) being surveyed.

Abstract: A system for monitoring the exposure of a plurality of individuals to a physical or chemical property associated with an environment. The system includes a plurality of portable devices. Each portable device is arranged to be worn or carried by an individual in the environment. The system further includes a control unit for communicating with each of the plurality of portable devices. Each of the portable device includes a detector arranged to measure a physical or chemical property that the individual wearing or carrying the device is exposed to in the environment; one or more physiological sensors each arranged to measure a physiological parameter of the individual; a geolocation module arranged to determine the location of the individual; and a communication module for communicating data collected by the portable device with other(s) of the plurality of the portable devices and with the control unit.

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 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.
