It is also cheaper for a hospital or a doctor's office to maintain a X-ray machine than an MRI or CT scan machine. Gamma rays are used to kill cancerous cells, which actually assures the fact that gamma rays are an advantage to medicine, but, at the same time could be very harmful indeed. Gamma rays are extremely powerful. This is called "Radiotherapy", and works because healthy cells can repair themselves fairly well when damaged by gamma rays - but cancer cells can't.Getting the dose right is very important! This means they can easily pass through medical equipment, … Advantages of gamma rays compared with X-rays. Gamma rays Side effects depend on techniques in nuclear medicine for diagnostic purposes, for example in the use by the ‘Bremsstrahlung’ method when the electrons are slowed down by atoms in being developed at a rapid rate. We can vary the energy of the gamma-rays we use and the type of absorbing material as well as its thickness and density.
