Radiation is extremely harmful to the body, which mainly results in the destruction of key biological macromolecules such as DNA and membrane proteins.
About 80% of the body is composed of water, radiation will cause the body of water ionization, resulting in a large number of free radicals, of which the most important is the hydroxyl radicals, these free radical diffusion distances can reach 2 times the molecular length of DNA, resulting in structural damage to DNA, which is likely to cause cancer.
Radiation therapy is a means of modern medicine for the treatment of tumors, it is a local treatment method to treat tumors by X alpha, beta, gamma ray and X ray therapeutic machine or accelerators, the radiation therapists in general hospitals work with radiation therapists, radiation technicians, and radiation therapists. In the course of radiation therapy, the radiotherapy equipment itself is a source of radiation through high linear energy transfer radiation, even in modern times, leaks still exist, and it is very difficult to repair DNA damage caused by ionizing radiation through drug intervention. Chinatungsten Online as a professional website dealing with tungsten for a long time, here to briefly introduce the anti radiation application of tungsten in the process of radiotherapy.
Tungsten has a high density, and lead is 60% higher, indicating that the same volume of radiation devices, tungsten, double the radiation resistance to lead, in addition, tungsten is resistant to high temperature, chemical and physical properties, stable, non-toxic and environmentally friendly. Therefore, most of the radioactive medical radiation equipment such as gamma knife, tungsten alloy X-ray sight, cancer treatment equipment, tungsten alloy syringe, the basic platform of tumor isotopes and accelerators and other equipment, the radiation shield are tungsten.
In addition, tungsten can be made of glass material or resin compound to make radiation proof glass. It can insulate the radiation source of the radiation chamber and operating room. Compared with the traditional lead material, tungsten material has stronger protection. Also, tungsten is also the main filler for industrial radiation protection clothing. Practice has proved that, whether medical or industrial equipment, compared with the traditional shield material lead, tungsten shielding effectiveness of more powerful, more environmentally friendly. With the popularization of nano materials, nano lead tungstate has gradually joined the ranks of anti radiation clothing filling materials in recent years.
