SUMMARY
The discussion focuses on calculating the number of atoms per cubic centimeter in radioactive water after cleanup at Three Mile Island, specifically concerning the isotope Cesium-137 (Cs-137). The initial activity is given as 156E-6 Ci/cubic cm. To find the number of atoms, the calculation involves converting Curie to decays per second and using Avogadro's number, resulting in approximately 6.86E17 atoms per cubic centimeter. The complexity arises from needing to consider the decay rate and half-life of Cs-137 for accurate calculations.
