What i think is due to the charger beta have negative charge and gamma has no charge free of charge
Highest penetration: Gamma (y) Second highest: Beta (B)Weakest penetration: Alpha (a)Explanation: The relative penetrating abilities of alpha, beta, and gamma radiation. The heavy, highly charged alpha particles are stopped by a piece of paper (or the skin). The lighter, less highly charged beta particles penetrate paper, but are stopped by a 0.5-cm sheet of lead. Because gamma rays have no charge and no mass, they are the most penetrating, but can be stopped by several centimeters of lead.
Alpha particles have much less penetrating power than gamma rays.
Gamma Beta Alpha
The most penetrating power is for beta particles compared to those given here.
Of the "basic" types of particulate radiation, the neutron has the highest penetrating ability. It is much more penetrating than the electron, positron, proton, or alpha particle.

Alpha radiation.
Alpha particles are positively charged. They have low penetrating power but high ionizing power.

Alpha particles have much less penetrating power than gamma rays.

Alpha Particles have very poor penetrating power. They can usually be stopped by an inch or so of air, or a sheet or two of paper, depending on their energy. However, because of their charge, they can be quite destructive.
