Radiation is everywhere in life, and radiation mainly consists of ionizing radiation and non ionizing radiation.

Generally speaking, ionizing radiation is the most harmful to human beings, and the major hazards are genetic variation and carcinogenesis. Scholars believe that a cell is composed of trillions of atoms. The probability of radiation caused by ionizing radiation depends on the radiation dose rate and the induction of radiation organisms. Alpha, beta, gamma radiation and neutron radiation can be accelerated to sufficiently high energy ionized atoms.
 
However, some special occupations of the work must be exposed to ionizing radiation, power plants, nuclear power plants, medical examinations, radar stations, etc., these occasions are basically ionizing radiation source, then what kind of radiation protection measures?
 
The most basic protection is to wear radiation protection equipment, such as clothing, gloves, hats. Of course, the general anti radiation clothing on the market is basically useless. In the past, industrial radiation protection clothing is made of lead PbO for coating. People who have been using it for decades have found that although lead can protect against radiation, the environmental pollution caused by lead is very serious.
 
Later, people came up with tungsten material instead of lead material as radiation protection clothing added layer. The study found that WO3 has a high density, which is the most critical factor in its excellent radiation protection. The tungsten shield is two times more efficient than the lead shield, and the weight of the tungsten shield is 25% to 50% less than that of lead. At the same time, tungsten is friendly to the environment, there will be no pollution such as lead toxicity, therefore, nuclear power plant shielding materials of radiation shielding barrel, industrial radiation protection equipment for nuclear test equipment, hospital radiotherapy equipment shielding very much with tungsten as raw materials.
 
Tungsten can be made of fiber and sheet, mixed with resin or rubber, and made of radiation resistant material to realize radiation shielding. However, it is difficult to produce a tungsten-containing hybrid material in the form of fibers due to the presence of fibers and high-density tungsten. But the advanced Japanese in textile technology seem to have solved the problem, Japanese companies have fused tungsten and fiber to make Kevlar fiber, and made garments, gloves and hats for sale in nuclear power plants and power plants, where ionizing radiation is used for a long time.
