Question

the linear absorption coefficient for 50-keV x-rays in sea-level air is 5 ×10 ^-3 By how much is the intensity of a beam of such x-rays reduced when it passes through 0.50 m of air​

Answer 1

Answer:

• The penetration values are then plotted as a function of aluminum-absorber thickness. The absorber thickness corresponding to a penetration value of 0.5 (50%) is the HVL. This value is referred to as the first HVL.
