Tungsten Alloy for X-ray

Tungsten alloy is used for shielding against X-ray in medical. With the development of radiation shielding for X-ray equipment, especially constantly carrying out radiation shielding and safety regulation or standard, awareness of radiation shielding is strengthened in generally. Now accidents caused by X-ray are few. However, in the past, if did not notice intermittent exposure to control irradiation of X-ray, it may cause radiation injury to the skin of patient and medical staffs’ hands when utilizing fluoroscopic viewing to carry out fracture reduction and searching foreign matter inside body. At the beginning of 1980’s, one hospital in China used 10mA portable X-ray equipment which had low effectiveness of shielding to search the bullet in buttock of a child who shot by air pistol. Medical staffs were lack of knowledge about radiation shielding and time of fluoroscopic viewing was too long. That caused II~III degree acute radiation burning accident to part skin of child. The child accepted symptomatic treatment in hospital for several moths and also needed skin grafting after half a year. It also happened that medical staffs could not control fluoroscopic viewing time, resulting in over irradiation of X-ray to medical staffs’ hands and radiation injury when carrying out fracture reduction and searching foreign matter inside body.

Traditionally, lead was used as raw material for radiation shielding. However, lead had toxicity which may cause pollution. The density of tungsten alloy is higher than lead by 60%. High density of tungsten alloy allows a reduction in physical sizes of shielding components without compromising effectiveness of shielding characteristic. Otherwise, tungsten alloy has the advantage of non-toxicity. Tungsten alloy is suitable for radiation shielding.
