Japanese research and development testing agents make radioactive cesium "present" radioactive materials invisible, colorless and odorless, and must be discovered with professional instruments. A research team in Japan has recently developed a detection agent that allows radioactive cesium attached to soil and other places to "present" and be visible to the naked eye after being irradiated with ultraviolet rays. According to the Japanese "Yomiuri Shimbun" report, this detection agent was developed by the Japanese Material Research Institute, and after it was spread on the surface of the soil containing radioactive cesium, the radioactive cesium would adhere to the detection agent; if it was irradiated with ultraviolet light It emits turquoise light, and this situation does not appear on the surface of the soil without radioactive cesium. After the Fukushima nuclear accident in Japan, the detection and removal of radioactive materials became an important issue. The above research team said that after confirming that this preparation has no adverse effects on humans and the environment, it can be used to detect radioactive cesium in public places, residence courtyards and plant surfaces.
