Tungsten Alloy Linear Accelerator

It has been reported that the linear accelerator can emit high energy X-rays or electrons to conform to a tumor's shape and destroy cancer cells while sparing surrounding normal tissue. So, tungsten alloy, as a radiation shielding material, is often used to medical linear accelerators to shield the high-energy X-rays generated by the accelerator during clinical radiotherapy treatment.

Generally, the accelerator features several built-in safety measures to ensure that it will deliver the dose as prescribed and is routinely checked by a medical physicist to ensure it is working properly. Besides, the accelerator should be sit in a room with tungsten alloy shield and concrete walls so that the high-energy X-rays are shielded and no one outside of the room is exposed to the X-rays. The accelerator only emits radiation when it is actually turned on, so the risk of accidental exposure is extremely low. But we still should pay much attention to the shielding of radiation as the medical linear accelerator has high power and strong radiation.
