Americium-241 is the most common isotope of americium. It is commonly found in ionization type smoke detectors and is a potential fuel for long-lifetime radioisotope thermoelectric generators. It decays to Neptunium-237 by alpha emission. How much energy (in joules) is given off by the decay? (235 Am = 241.056 amu; 233Np = 237.048 amu; He= 4.0026 amu; 1 amu = 1.661x10-24 g.) 95 Hint: Am → 233Np + He+y 235 -8.06x10-11 J -8.07x10-15 -8.07x10-12 J O -8.07x10-13 J
A moon rock collected by a U.S. Apollo mission is estimated to be 4.00 billion years old by uranium/lead dating. Assuming that the rock did not contain any lead when it was formed, what is the current mass of Pb206 in the rock, if it currently contains 1.430 g of U238? The half-life of U238 is 4.47×109 years.
PET studies require fluorine-18, which is produced in a cyclotron and decays with a half-life of 1.83 hours. Assuming that the F−18 can be transported at 59.0 miles/hour, how close must the hospital be to the cyclotron if 64% of the F−18 produced is to make it to the hospital? Express your answer using two significant figures.
