Exercise 1.3 Air composition can be considered to be mostly 80mass%N2 and
20mass%O, and its density is 1.29 x 10-3Mg/m3 g/cm3 at normal temperature
(273.15 K) and pressure (101,325 Pa). If Cu-Ka radiation passes through 360 mm
of normal air, by what percentage is the intensity reduced. Perform a similar calcu-
lation for the Fe-K radiation.
