What is radiation protection?
Radiation protection, sometimes called radiation shielding, is the protection of people and the environment from the harmful effects of ionizing radiation, which includes both particle radiation and high-energy electromagnetic radiation.
Ionizing radiation is widely used in industry and medicine, but presents a significant health risk. It causes microscopic damage to living tissue, causing skin burns and radiation sickness at high risk and statistically elevated risk of cancer, tumors and genetic damage at low risk.
As medical science develops so repaid, there is more and more radiation in our lives, which has become a new problem, such as the radiation of X-rays, gamma rays (high-energy electromagnetic radiation), alpha particles (helium atoms), beta particles (electrons) and cosmic radiation, etc.
In order to protect patients and others from the harmful effects of ionizing radiation, such as breast cancer, skin cancer, etc., a safe and excellent class of radiation absorbing media is important.
Advantages of Tungsten alloy Radiation Shielding
Experts have found that radiation exposure can be reduced by Tungsten Alloy Shielding. The density of a material is related to its radiation stopping ability. Higher density means better stopping power and shielding. Due to higher density, tungsten alloy has higher stopping power than lead. Gamma rays, their greater linear attenuation means less shielding is needed for equal amounts. Tungsten shielding or equivalent provides less exposure risk than equivalent lead shielding.
Tungsten alloy is a suitable raw material for radiation protection, as a combination of density (60% more dense than lead), machinability, good corrosion resistance, high radiation absorption (superior to lead), simplified life cycle, and high strength. It can provide the same degree of protection as lead while significantly reducing the overall volume and thickness of shielding and containers. In addition, compared with lead or depleted uranium in the past, tungsten alloys are more acceptable in this case because they are non-toxic.
Tungsten Alloy Electrical Radiation Protection
The use of tungsten alloys in radiation protection is not subject to special NRC, EPA, or OSHA regulations and therefore has been widely used, such as:
Radioactive source containers
Gamma radiography shields
Shielding blocks
Oil logging, industrial instrumentation source holders
X-ray collimators
Tungsten alloy PET syringe shielding
Shielding machines in cancer treatment
Radioactive injection syringe protection
Tungsten syringe shielding
Nuclear shielding walls
