Device for measuring large-area radioactive surface contamination
A recently granted patent (Publication Number: US11867851B2) discloses a large-area radioactive surface contamination measurement device. The device includes a frame body with multiple holes, a mover to move the frame body, radiation detection modules in the holes to detect alpha, beta, and gamma rays, and a control unit to calculate the location and level of radioactive contamination by comparing detection values. Each radiation detection module consists of a counter with seating wings, a photomultiplier tube, and a channel unit mounted on the tube. The device also features casters for mobility, a height adjustment switch, and real-time detection information processing capabilities to create a radioactive detection map.
Furthermore, the patent claims detail additional features such as the uniform size and shape of the holes, perpendicular alignment of the holes to the frame body and mover, and the ability to detect different types of radioactivity with multiple channel units on some photomultiplier tubes. The device's control unit is equipped with a computing mechanism to assign identifiers to detection modules, calculate detection values, and generate real-time radioactive detection maps based on the device's movement trajectory. These claims highlight the device's versatility, mobility, and advanced data processing capabilities for efficient large-area radioactive contamination monitoring.
