In this video, you will learn this model answer:
X-ray machines in hospitals use an electromagnetic wave called X-rays to produce images that can tell if you have broken bones.
X-rays aren’t absorbed by the fleshy, less dense parts of the body. X-rays are absorbed by the more dense bones.
So if there is a break in the bone, the X-rays will not be absorbed by the bone that is broken, and it will pass through it to the detector plate, which turns black.
Gamma rays are used in radiotherapy, which treats cancer. High doses kill living cells, so gamma rays are directed at the cancer cells, which kills them.
Even though it is dangerous to use gamma rays, it is more dangerous to have cancer.
