A beam of nuclei is used for cancer therapy. Each nucleus has an energy of 125 MeV, and the relative biological effectiveness (RBE) of this type of radiation is 16. The beam is directed onto a 0.180-kg tumor, which receives a biologically equivalent dose of 253 rem. How many nuclei are in the beam?

A radioactive isotope of phosphorus, 32P, is used in internal radiotherapy to treat patients with cancers and other diseases of the bone marrow. 32P has a half-life of 14.28 days and a atomic mass of 32P is 31.973 u. Via β decay, it emits an electron with an energy of 705 KeV and a RBE of 15.5 . As part of a treatment program, a patient ingests a radioactive pharmaceutical containing 32P which has an initial activity of 1.33 MBq....

Constants A cyclotron is used to produce a beam of high-energy deuterons that then collide with a target to produce radioactive isotopes for a medical procedure. Deuterons are nuclei of deuterium, an isotope of hydrogen consisting of one neutron and one proton, with total mass 3.34 x 10-27 kg. The deuterons exit the cyclotron wit a kinetic energy of 4.80 MeV You may want to review (Pages 778 - 783)

In proton beam therapy, a beam of high-energy protons is used to kill cancerous cells in a tumor. In one system, the beam, which consists of protons with an energy of 2.8×10−11J, has a current of 84 nA. The protons in the beam mostly come to rest within the tumor. The radiologist has ordered a total dose corresponding to 3.2×10−3J of energy to be deposited in the tumor. Part A How many protons strike the tumor each second? Express your...
