Answer:
alpha rays
Explanation:
The penetrating power of alpha particles, beta particles, and gamma rays varies greatly. Alpha particles can be blocked by a few pieces of paper. Beta particles pass through paper but are stopped by aluminium foil. Gamma rays are the most difficult to stop and require concrete, lead, or other heavy shielding to block them.
