Know Tungsten – Tungsten Alloy Radiation Shielding Container 88

? Compared with traditional shielding materials, such as lead and boron carbide, tungsten alloy shielding container have a higher density with smaller shields of the same weight. Compared with lead shielding of the same weight, the volume of tungsten alloy shielding is only 1/3 of lead, but its high density makes it have the same radiation absorption capacity as lead. After the weight is determined, the density is higher, but the thickness of the tungsten alloy is thinner. Due to…
