Can lead stop the laser?

Of course. Lead has a large atomic weight, so its atomic potential energy is high. In order to let light pass, a faster and larger energy barrier is needed. The energy of laser is less than the potential energy of lead, so lead-shielded lead plate is a common material for nonferrous metals. Where can it be used? First of all. Hospital. Hospitals are used for radiation shielding protection. The intensive care unit of conventional hospitals is divided into ct room and Dr room. It can be protected by lead plate. According to the protection effect, different thicknesses are adopted for different radiation sources of the equipment. Common ones are 2mm and 3mm. Second. X-ray machine X-ray machine used for baggage inspection has radioactive sources inside. The inner layer of the equipment will be covered with a layer of lead plate to block the harm of radiation to human body. Third. Chemical industry. Lead plate will be used as anti-corrosion material in chemical industry. Fourth. Electrolytic electroplating industry. Electrolytic zinc and electrolytic copper will use lead plate as anode plate. Precipitation of the anode product is carried out. Fifth. Fishing enthusiasts.
