- (a) Neutron activation of sodium, which is 100% 23Na, produces 24Na, which is used in some heart scans, as seen in Table 32.1. The equation for the reaction is 23Na+n24Na+ . Find its energy output, given the mass of 24Na is 23.990962 u. (b) What mass at 24Na produces the needed 5.0mCi activity, given its halflife is 15.0 h?arrow_forwardIn the following eight problems, write the complete decay equation for the given nuclide in the complete XZAN notation. Refer to the periodic table for values of Z. decay of 210Po, the isotope of polonium in the decay series of 238U that was discovered by the Curries. A favorite isotope in physics labs, since it has a short halflife and decays to a stable nuclide.arrow_forwardThe particles emitted in the decay of 3H (tritium) interact with matter to create light in a glow- in-the-dark exit sign.

- Data from the appendices and the periodic table may be needed for these problems. There is more than one isotope of natural uranium. If a researcher isolates 1.00 mg of the relatively scarce 235U and finds this mass to have an activity of 80.0 Bq, what is its halflife in years?arrow_forwardThe naturally occurring radioactive isotope 232Th does not make good fission fuel, because it has an even number of neurons; however, it can be bred into a suitable fuel (much as 238U is bred into 239P). (a) What are Z and N for 232Th? (b) Write the reaction equation for neutron captured by 232Th and identify the nuclide AX produced in n+232ThAX+. (c) The product nucleus β decays, as does its daughter. Write me decay equations for each, and identify the final nucleus. (d) Conform that the final nucleus has an odd number of neutrons, making it a better fission fuel. (e) Look up the halflife of the final nucleus to see if it lives long enough to be a useful fuel.arrow_forwardTwo fusion reactions mentioned in the text are n+3H4He+ and n+1H2H+. But reactions release energy, but the second also creates more fuel. Confirm that the energies produced in the reactions are 20.53 and 2.22 MeV, respectively.
