AL-FS120α. β Surface Pollution Monitor

The AL-FS120 type alpha and beta surface pollution monitoring instrument has a large detection window, high detector efficiency, and can be applied to surface pollution measurement in various occasions. Mainly used for measuring alpha and beta radioactive surface contamination, it is widely used in places that must be monitored due to potential contamination, such as nuclear power plants, reprocessing plants, retired or dismantled nuclear facilities, radioactive waste treatment plants, hospitals, research institutes, and various environments. It can be used for surface contamination monitoring of walls, floors, tables, hands, feet, clothing, or other objects.
