- Question: I have received 54 greys of radiation therapy over six-and-a-half weeks for my brain tumor. The machine used was called Cobalt. What is the difference of using Cobalt vs a machine called linear accelerator? Also, how long can the above mentioned radiation have an effect on the tumor? More than 4 months after the last radiation day?
The distribution of the radiation is different. In general, there is less ability to perform sophisticated radiation on a cobalt machine. Details of the case would be helpful to determine the reason for cobalt.
