Money represents more than the paper it's printed on. It is the embodiment of your time, your talents, and your commitments. It buys the food you eat, the house you sleep in, the car you drive, and the clothes you wear. It also helps provide you with the lifestyle you want to live once you retire. You have spent a lifetime earning it, spending it, and hopefully, accumulating it. When the time comes for retirement, you want your money to provide you with a comfortable lifestyle and stable income after your working days are done. You might also have other desires, such as traveling, purchasing property, or moving to be closer to your family (or farther away). You may also want your assets to provide for your loved ones after you are gone. The truth is that it takes more than just money to fulfill those needs and desires. Your income, your plans for retirement, your future healthcare expenses, and the continued accumulation of your assets after you stop working and drawing a paycheck all rely on one thing: You.

The expected fluxes of gamma ray lines were calculated for four lunar compositions and one chondritic chemistry from a consideration of the important emission mechanisms: natural radioactivity, inelastic scatter, neutron capture, and induced radioactivity. The areal resolution of the experiment was calculated to be around 70 to 140 km under the conditions of the Apollo 15 and 16 experiments. Finally, a method was described for recovering the chemical information from the observed scintillation spectra obtained in these experiments.
