Tungsten Alloy Radiation Shielding For X-ray Machine

An X-ray machine is a device used to generate X-rays. It is made up of a control console which enables the x-ray technician to choose a variety of x-ray techniques suitable for that specific exam, an X-ray generator that creates and produces the desired KV, MA and X-ray tube. The X-ray tube, like any vacuum tube, contains a cathode, which directs a flow of electrons into a vacuum, and an anode, which collects the electrons and is made of tungsten to disperse the heat generated by the collision. When the electrons collide with the target, about 1% of the resulting energy is emitted as X-rays, with the remaining 99% released as heat. Due to the high energy of the electrons that reach relativistic speeds the target is usually made of tungsten even though other materials can be used particularly in XRF applications. The types of X-ray machine include the portable medical X-ray system, the industrial X-ray detection machine and the belt detection X-ray machine. X-ray machines are widely used in hospitals to help doctors diagnose the disease, in industry for non-destructive testing and in railway stations and airports to carry out security checks.

X-ray is a form of electromagnetic radiation. Most X-rays have a wavelength ranging from 0.01 to 10 nanometers, in line with frequencies in the range of 30 petahertz to 30 exahertz and energies in the range of 100 eV to 100 keV. The wavelength of the X-ray is shorter than that of UV ray and typically longer than that of gamma ray. In many languages, X-radiation is referred to with terms meaning Röntgen radiation, who is usually credited as its discoverer, and who had named it X-radiation to signify an unknown type of radiation. X-ray has penetrating effect, ionizing effect and thermal effect. In medicine it is often used for fluoroscopy, in industry for industrial flaw detection. Since the X-ray has a strong penetrating effect, when a living organism is irradiated with X-ray, its living cells can be inhibited, destroyed and even killed, resulting in varying degrees of changes in physiology, pathology and biochemical aspects. In the use of X-ray technology, it also found that X-ray can lead to the patient hair loss, skin burns and can cause vision disorder, leukemia and other ray injury problems on the related personnel.

Tungsten alloy radiation shielding can be used to shield X-ray generated by the X-ray machine. Compared with conventional shielding materials (such as lead), tungsten alloy shielding reflects good value. Since the tungsten alloy has a high density, under the condition of the same thickness, the radiation shielding ability of tungsten alloy is twice than that of lead shielding, and the weight of tungsten alloy shielding is 25 to 50% less than lead. In addition, lead is toxic and tungsten alloy shielding is non-toxic so that it will not harm the human body or pollute the environment.
