Calculate the binding energy for Zn-64, in GJ.

lodine-131 is used to treat Graves disease, a disease of the thyroid gland. The amount of 1311 used depends on the size of the gland. If the dose is 86 microcuries per gram of thyroid gland, how many grams of 131| should be administered to a patient with a thyroid gland weighing 26 g? Assume all the iodine administered accumulates in the thyroid gland.

Calculate the energy released (in J) from the following nuclear reaction: 국H + 3H→He + 할 H = = 1.007 825 032 24 amu H = 2.014 101 778 11 amu H = 3.016 049 281 99 amu

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.

3. MEX The specific activity of 14C in the biosphere is 0.255 Bq/g. What is the age of a piece of papyrus from an Egyptian tomb if its beta counting rate is 0.153 Bq/g? The half-life of 14C is 5730 years.
