C+Cobalt-60

=__Isotope and Radioactivity__= =-= = = =Name of radioactive isotope/electromagnetic radiation/scientist:= = = Cobalt-60 is a radioactive isotope. 60Co =Explanation of interesting facts: (how used/works.experiments/discoveries)= 1. Cobalt 60 isn't found in nature.

2. It decays by negative Beta decay into the isotope Nickel-60.

3. Used for Radiotherapy in hospitals

4. Cobalt-60 can be made in a nuclear reactor such as the CANDU reactor.

5. Used for radiographing

=3 Advantages of using the radioactive isotope/radiation/benefits of discovery=

1. The Gamma Rays that are emitted from cobalt-60 kill pathogens and bacteria without damaging what is being exposed to the rays.

2. Can treat cancer.

3. Cobalt 60 can sterilize medical equipment.

=3 Disadvantages of using the radioactive isotope/radiation/discovery:= 1. Internal exposure (absorption of 60Co in kidney, liver, bones) to the gamma rays emitted from Cobalt 60 can result in cancer.

2. External exposure to radiation can result in burns, radiation sickness, and death.

3. Has a short half life. Can be used as a radioactive nuclear weapon that will destroy everything in a short time before decaying.

=Is the radioactive isotope/radiation/discovery still used today? Explain= Cobalt-60 is still used today for radiotherapy, radiographing, leveling devices, and thickness gauges.
