Beta particle.

Reason: Beta particles (high-energy electrons) can travel several feet in air and are stopped by relatively thin solid shielding (plastic, glass, or aluminum). Alpha particles travel only centimeters; gamma rays and neutrons are much more penetrating and require heavy/dense or hydrogenous shielding.
