What is the initial activity of a 5 g radioactive source of 60Co given that the specific activity of 6⁰Co is 4.8 x 1016 Bq/kg? How many decays per second does this correspond to? After twenty years what activity does this source still provide if 6⁰Co has a half life of 5.3 years? What is the initial intensity, I, of the 5 g 6⁰Co source at a distance of 1m if the gamma rays emitted by 6ºCo have an average energy of 1.9 x 10-1³ J?
Ruthenium-106 (106Ru) is used to treat melanoma in the eye. This isotope decays by β– emission with a half-life of 373.59 days. One source of the isotope is reprocessed nuclear reactor fuel. How many protons and neutrons does the 106Ru nucleus contain? Identify the missing daughter nucleus in the β– emission decay of 106Ru below. How many years after 106Ru is implanted in the eye does it take for its decay rate (or activity) to be reduced to 27.5% of the initial decay rate? Use 1 year = 365 days.
