WebExternal beam therapy (EBT) is a method for delivering high-energy x-ray or electron beams to a patient's tumor. Beams are usually generated by a linear accelerator and targeted to destroy cancer cells while sparing surrounding normal tissues. EBT also may be used to relieve symptoms in patients with advanced cancer or cancer that has … WebIn addition to the self-sustaining chain reaction, it is also possible to bombard suitable atoms (targets, such as lead or bismuth) with secondary particles, e.g. protons, thereby producing free neutrons. However, this reaction is not self-sustaining and comes to an end when the bombardment stops.
