Does radiation therapy expose people to radioactive substances?
Many people, when they hear the word radiation, think immediately of radioactive substances. However, no radioactive substances are involved in the creation of X-rays or electrons by a medical linear accelerator. When a linear accelerator is switched on, radiation is produced and aimed directly at cancer cells. Then, like a flashlight, when the machine is switched off, there is no more radiationnone is stored or transported.
