The production of radio nuclides can involve: a. The addition of a neutron into a stable nucleus b. Capturing a negative electron from the K-shell (electron capture) c. Addition of a proton into the nucleus using a nuclear reactor d. The use of a cyclotron e. Removal of electrons from the inner shell

Answer»

a. True. This is one of the methods by which radio nuclides are produced. The process takes place in a nuclear reactor. 

b. False. Electron capture is a form of radioactive decay. 

c. False. The forceful addition of a proton into the nucleus causing the ejection of a neutron is also one of the methods by which radio nuclides are produced. However, this process takes place in a cyclotron, which accelerates charged particles, e.g. protons, onto the target material. 

d. True. 

e. False. Radioactivity involves the nucleus.
