There’re great medical benefits of using X rays in medicine, but they also have certain hazards. With the rapid popularization of medical X ray machine, Radiation hazards of X ray machines have also attracted extensive attention.

The construction of hospital X ray room, shielding design and the use and management of X ray machine must be supervised by the health supervision department. The hospital attaches great importance to the treatment of patients with radiation shielding. Using tungsten alloy shielding can reduce the patient's exposure dose to reduce the risk of radiation.

 

The leaking rays from X ray tube protective sleeve, useful ray emitted from the X ray tube window, and scattering rays produced by scattering at different X - ray tube voltage, the dose is different, and the harm to people is also different. As for X - ray room shielding design, it needs to consider X ray tube pressure, tube wave, projection time, reference point, distance from source, and the thickness of the shielding material to determine the transmission coefficient of shielding materials.

 

 

After careful calculation, tungsten alloy has the most distinct advantages to be a medical X ray room shielding device, which includes the main protective wall of the machine room, protective door, and observation window, etc. Tungsten alloy shield has high density, which is an important parameter affecting the shielding performance and is the most significant advantage of tungsten alloy. A tungsten alloy shield has only 1/3 of lead in volume but having the same ray absorbing power as lead when they have the same weight.

 

As tungsten alloy has higher density, the wall thickness can be thinner. Tungsten alloy high hardness makes it easy to prolong the service life of the shield. The harm to human or environment of tungsten alloy has not been found yet. This non-toxic and environmental friendly material is sure to be more and more popular.
