Tungsten Alloy Radiation Protection Window

With the development of science and technology, radiation technology has been widely used in biological research, medicine, industry and agriculture. In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. It can be divided into ionizing radiation and non-ionizing radiation depending on its energy level and its ability to ionize substances. The word “radiation” generally refers to ionizing radiation. Ionizing radiation are mainly α, β and γ radiation three kinds. Beta-ray is a stream of electrons which moves at high-speed and has strong penetrating power; alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium nucleus; γ-ray, also known as the stream of γ particles, is released by nuclear energy level transition, and its wavelength is shorter than 0.01 Å. γ-ray can be used in the industry for industrial flaw detection or automatic control of the pipeline.

Although radiation brings a lot of convenience to people's lives, but its hazards also need to be valued. Such as γ-ray has a strong penetration power. When the body is exposed to γ ​​rays, γ-rays can enter into the interior of the human body and interact with the cells in vivo, to corrode the complex organic molecules (such as proteins, nucleic acids and enzymes), and thus interfere with the normal chemical processes in the human body, and even cause cell death. In addition, ionizing radiation can alter the chemical balance of the cell (sometimes cause cancer) and damage the genetic material in the cells in the body, leading to fetal malformation and congenital leukemia. So the installation of tungsten alloy radiation protection window in radioactive laboratories and other places which can release radiation is necessary.

Tungsten alloy radiation protection window is made up of tungsten heavy alloy with high-density. According to the research, the radiation shielding properties of a metal material increases with its density. Compared with other traditional materials (such as lead), tungsten alloy has higher density, thus it has greater radiation shielding performance to avoid radiation damage.
