Penetrating ability beta particles

This radiation release often accompanies the release of alpha or beta particles because of the high energy arrangement left in the nucleus after the release of alpha or beta particles. Gamma radiation has the greatest penetrating ability. Concrete, 6 inches thick, is needed to stop gamma radiation. 

The penetrating abilities of the particles and rays are proportional to their energies. Beta particles and positrons are about 100 times more penetrating than the heavier and slower-moving alpha particles. They can be stopped by a g-inch-thick (0.3 cm) aluminum...

The lower energy and short penetration ability of beta particles requires a scintillator in direct contact with the decaying isotope. This is accomplished by dissolving or suspending the sample in a liquid fluor. Counters which use this technique are called beta counters or liquid scintillation counters. 

How does the penetrating ability of gamma rays compare with that of alpha particles and beta particles ...
