Radiation mainly consists of ionizing radiation and non ionizing radiation. In general, ionizing radiation is harmful to human beings, and its harm is genetic variation and carcinogenesis.

At present, China's power plants, nuclear power plants and some other people who need long-term exposure to radiation, their radiation protection measures is the most basic anti-radiation equipment. Based on the high standards and requirements of radiation protection, at present China mainly uses lead tungstate as the main filling material. Where is the advantage of lead tungstate radiation protection?
 
In the past, the production of various radiation protection equipment was usually made of lead as filler, so as to make gloves, clothes, hats and so on, which could protect the gamma rays. But lead easily migrated from the clothing and caused harm to people and the environment. Later, foreign countries generally use WO3 instead of lead, WO3 effect is good, but also environmental protection, but the disadvantage of WO3 is poor mechanical performance, in particular, the tungsten rubber radiation protection gloves, the tensile strength of only 4 ~ 6 MPa, elongation at break of 500% to 700%, accidentally broken, it is difficult to adapt to difficult operations.
 
Recently, Chinese scholars have found that using nano lead tungstate as filler can not only greatly improve the radiation protection ability of products, but also have better mechanical properties. Lead tungstate has the advantages of high density, short radiation length, fast scintillation decay time and strong radiation resistance, so it is suitable to be used for radiation shielding. In addition, when lead tungstate is used in nanometer form to resist radiation apparatus, uniform particle size can protect the radiation suit from excellent radiation resistance and good mechanical performance.
 
China is a big producer of tungsten. When foreign countries still use PbO or WO3 as filler of radiation protection clothing, our country has already popularized the use of lead tungstate as radiation protection equipment and shielding device. Compared with lead, nano - tungstate not only does not pollute the environment, but also photocatalyst degradation of organic pollutants to improve the environment; Compared with WO3, nano lead tungstate not only increases the shielding rate of gamma radiation by 5%, but also increases the tensile strength greatly, the risk of exposure to radiation was also substantially reduced and the operation was more secure, so it can said that lead tungstate was the king of radiation protection equipment.
