Alpha decay in cancer therapy. Certain radionuclides decay by emitting an alpha particle. To treat bone cancer, an alpha emitter such as radium 223 Ra is attached to a carrier molecule that is then taken up by bone as though it were calcium. What is the daughter atom if the parent atom is (a) radium Ra, (b) radium Ra, and (c) actinium Ac? 225 Include the mass number and the charge number of the element with the symbol. For example, if "iodine 13" is the correct answer, enter* 1311" in the box. (Use the Chem input panel.) Alpha decay in cancer therapy. Certain radionuclides decay by emitting an alpha particle.
