It is only slightly radioactive.The radioactivity is minimal so it is typically seen as nonradioactive. (c) Estimate how much of the sample of 500 grams will remain after 10 years. This pink color is because of its oxide coating. Radioactive nonprimordial, but naturally occurring on Earth. The last remaining stable isotope of bismuth, bismuth-209, was observed to decay in 2003, with a half life estimated at 1.8×10 19 years. Also, because I neglected to provide any earlier, Bismuth is only naturally found as one isotope, which is the almost nonradioactive one.Its radioactivity was predicted by scientists and proven by analyzing the metal. In fact its major isotope bismuth-219 was predicted to be so back in 1949. But not quite. 3. Bismuth goes through the refining process as crude lead bullion. Start studying CHEM 1010 CHPT 5 - FARRELLY. However, in 2003 it was discovered to be weakly radioactive: its only primordial isotope, bismuth-209, decays via alpha decay with a half life more than a billion times the estimated age of the universe. Liquid bismuth has been used as a fuel carrier and coolant in the generation of nuclear energy.
