The measurement of α/β radioactive surface contamination level is one of the necessary steps in the radioactivity monitoring work, and the measurement result is also an important basis for determining the contamination. For workplaces prone to radioactive contamination, routine contamination monitoring on the ground and equipment surface should be carried out regularly, which is very important to prevent contamination diffusion and reduce unnecessary exposure of personnel to radiation. At present, most of the α/β surface contamination monitors are portable (hand-held or vehicle-mounted) monitoring devices, but there are the following two problems: First, the detection area of portable monitoring device is small, resulting in low monitoring efficiency and time-consuming, which unable to meet the needs of the surface contamination monitoring in the entire area of radioactive sites. Second, after the nuclear accident, the level of surface contamination in radioactive sites is relatively high, and direct measurement of personnel will inevitably result in different degrees of radiation damage. Therefore, in order to solve the above problems, an intelligent robot for surface contamination monitoring has been developed. Based on an array of large-area surface contamination detectors, combined with positioning and navigation (SLAM) and wireless transmission technology, it has realized the autonomous, rapid and remote intelligent monitoring of surface contamination in the entire area of radioactive sites. The device not only reduces the unnecessary radiation to personnel, but also improves the level and intelligence of radiation monitoring device.
