SUMMARY
The discussion focuses on calculating the ionizing intensity of X radiation, which ionizes 26.2 x 1012 atoms per cubic centimeter. To convert this measurement into roentgens, it is essential to understand that 1 roentgen corresponds to the generation of approximately 2.08 x 109 ion pairs in 1 cm³ of air at standard temperature and pressure (STP). The key step involves determining the number of ion pairs produced per ionization event from the given atom count.
