Tungsten Radiation Shielding

1. Product name：Tungsten radiation shielding

Tungsten radiation shields are made from flexible heat-resistant shields immersed in silicone polymer ferrotungsten metal powder. Although lead blocks have been used in shields for many years, shields made of lead are not efficient enough by comparison. Due to the highest weight ratio between energy and worker, the new generation of tungsten shields has been shown to be twice as efficient as lead shields.

The shape of the tungsten radiation shield is custom designed by the customer to be less radiation than the equivalent weight of a traditional lead block. Additionally, tungsten shields weigh 25 to 50 percent less than lead, while eliminating attendant toxic hazards and reducing mixed waste disposal costs.

Tungsten alloy is the best material for shielding, whether it is medical or industrial equipment. Compared with traditional shielding materials, tungsten alloy shields represent a good value. High-density alloys can provide the same energy absorption with less than 1/3 the volume of lead. One can take advantage of the reliable shielding properties of tungsten alloys. Tungsten alloy shields can protect people well from harmful radiation.

2. Classification of tungsten radiation shielding

a. Syringe shield

The tungsten alloy syringe shield is made of tungsten alloy as raw material and is a medical device used for protection during medical injection of radiopharmaceuticals. The Tungsten alloy syringe shield is the shielding effect of high-density tungsten alloy on radioactive particles. The density of tungsten alloy can reach 16.5-19.0g/cm3, which has a good shielding effect on radioactive particles.

Tungsten alloy syringe shields are often used as injection instruments for isotope tracing to monitor the efficacy of drugs in medicine. Using the nuclear physical properties of radioisotopes to continuously emit characteristic rays, nuclear detectors can be used to track its position, quantity, and transformation in vivo or in vitro at any time. Although stable isotopes do not emit rays, they can be used to correspond to ordinary The mass difference between isotopes is measured by mass spectrometers, gas chromatography, nuclear magnetic resonance, and other mass analysis instruments. If radioactive substances irradiate the human body or enter the human body, it will cause cell lesions, which will seriously endanger human life. The tungsten alloy shielded needle can protect the human body from harm when using radioactive substances.

b. Tungsten alloy shielding tank

Tungsten alloy shielding cans are also a type of tungsten alloy shielding product, which are used as containers for radiopharmaceuticals in medical treatment. Radiopharmaceuticals are a special class of drugs containing radionuclides for medical diagnosis and treatment. A radionuclide-labeled compound or biological agent is used for medical diagnosis or treatment in the body. Such as radiotherapy drugs 32P, 89Sr, 90Y, etc., which emit pure β-rays. Tungsten alloy shielding cans are mainly used to shield medical radioactive injections, medicines, and radioactive sources materials such as X and gamma rays. Tungsten alloy shielding cans are also used for shielding radioactive materials such as geological exploration.

3. Production process of tungsten radiation shielding

The sintering process is the main production process of tungsten alloy shields. Sintering is a heat treatment process in which the strength and density of the compact or powder body are very low. To improve the strength of the compact or the powder body, it is necessary to perform heat treatment under appropriate conditions. This is to heat the compact or loose powder to a temperature below the melting point of its basic components (about 0.7~0.8T absolute melting point), and keep it warm at this temperature so that the powder particles are combined to improve their performance. Chentian Company adopts the most advanced multi-atmosphere vacuum furnace for sintering.

Sintering has a decisive influence on the properties of tungsten alloy shields. As a result of sintering, bonding between powder particles occurs, the strength of the sintered body increases, and in most cases, its density also increases. During the sintering process, the compact undergoes a series of physical and chemical changes, starting with the evaporation or volatilization of moisture or organic matter, the removal of adsorbed gas, the elimination of stress, and the reduction of oxides on the surface of powder particles; followed by diffusion between atoms, paste flow and plastic flow, the contact surface between particles increases, recrystallization occurs, grain grows, and so on.
