B+Technicium-99

=__Isotope and Radioactivity__= = = =Name of radioactive isotope/electromagnetic radiation/scientist:= Technicium-99 = = = = =Explanation of interesting facts: (how used/works.experiments/discoveries)= =3 Advantages of using the radioactive isotope/radiation/benefits of discovery=
 * 1) Used to detect breast cancer
 * 2) Occurs naturally in minute amounts
 * 3) Emits beta particles in decay to produce stable isotope ruthenium-99
 * 4) Discovered by Carlo Perrier in 1937
 * 5) Most widely used radioisotope for diagnosing diseased organs

1.Destroys cancerous cells

2.Identifies cancer cells

3.Gamma rays map body, allowing easier location of cancer

=3 Disadvantages of using the radioactive isotope/radiation/discovery:= 1.Can destroy healthy cells

2.Short half life, 6 hours (must be used in the hospital it is produced in)

3.Many methods produce a product of "standard" purity

=Is the radioactive isotope/radiation/discovery still used today? Explain= Technetium-99 is still used today. However research is continued for a better more more efficient way to find and destroy cancer cells.
