Although tungsten alloy shield has good radiation protection performance, mechanical properties, compressive strength, and environmental friendly, but its price is 13 times higher than lead shield, so choose the right shielding materials based on different occasions, individual equipment surrounding and efficient use.
For example, in nuclear power plants, due to the adaptability of existing inventory, cost and lead shielding materials stocks, replacing the overall lead with tungsten is not realistic. Under normal conditions, when the lead shielding can meet the requirements although reducing the amount, there is no need to use tungsten shielding. When faced with specific applications, such as underwater applications, the shield case structure, or severely limited space, or the mechanical properties and mechanical strength such important places, tungsten shielding can effect the function.
