What Are The Types Of Radiation?
There are a myriad of radiation techniques, ionizing radiation destroys any tissue the beam passes through. Killing cells and altering genes to end any further reproduction of the deadly cancer cells. Photon beams are a type of ionizing radiation, it being the most common choice among radiation therapy, because it has the strongest effect on cancer. It is a high energy beam penetrating the skin invasively, to kill and destroy cancer cells. The radioactive substance needed to do this procedure comes from cesium, cobalt, and other man made sources of radiation. Another type of ionizing radiation is the particle beam. Used less than the photon beam, the particle beam uses a weaker source of radiation. Due to the weakness of the beam this type of radiation must be used in glands, and cancers close to the skin at the surface of the body. Often this radiation is used when other forms do not work on ones cancer.
Who Works With Radiation?
