A patient is given 0.050 mg of technetium-99m where m means Meta stable - an unstable but long-lived state, a radioactive isotope with a half-life of about 6.0 hours. Explain how long until the radioactive isotope decays to 6.3 x 10(-3) mg?
Explain the three basic types of radioactive particles as well as how they are formed. Give an instance of how each is related to our daily lives.
