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.

Question 12- The half-life of Fa-282 is 6.0 hours. If a sample of Fa-282 has an original activity of 192 mCi, what is the radioactivity of the sample of Qu-280 after 1 day? (Please show all of your work so I can understand going forward, also please look at the attcahed images for a special periodic table that you may need to use to help solve the question.)
Be sure to answer all parts. A freshly isolated sample of 90Y was found to have an activity of 2.9 x 105 disintegrations per minute at 1:00 p.m. on December 3, 2006. At 2:15 p.m. on December 17, 2006, its activity was measured again and found to be 7.7 x 10° disintegrations per minute. Calculate the half-life of 90Y. Enter your answer in scientific notation. x 10 minutes
