=__Isotope and Radioactivity__= = = =Name of radioactive isotope/electromagnetic radiation/scientist: Neutron Activation Analysis=

= = = = =Explanation of interesting facts: (how used/works.experiments/discoveries)=
 * 1) Converts stable isotopes to radioactive isotopes.
 * 2) Used to determine composition of materials.
 * 3) Scientists take a sample of a substance. Then they shoot neutrons at it. Some neutrons are absorbed into the atom and turn the sample radioactive.
 * 4) Scientists then study the radiation given off to identify the elements in the sample.
 * 5) Portions of the energy released is often in the form of gamma radiation.

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

1. To identify elements in samples.

2. Nearly 70% of the elements on the periodic table and be analyzed by NAA.

3. Neutron activation can be applied to any element with the right isotope. =Is the radioactive isotope/radiation/discovery still used today? Explain= Yes Neutron Activation Analysis is stil used to this day. It is a very good technique for identifying elements and analyzing them.
