Concept

Problem: In proton beam therapy, a beam of high-energy protons is used to deliver radiation to a tumor, killing its cancerous cells. In one session, the radiologist calls for a dose of 4.9×108 protons to be delivered at a beam current of 120 nA.How long should the beam be turned on to deliver this dose?
