Alpha particles has very less penetration power, beta particles has more penetration power than alpha and gamma rays have highest penetration power.
So a pair of normal gloves would be sufficient to shield alpha particle radiations.

write a summary : 5.4.4 Radiological Hazards Radiological hazards can be divided into three general forms: alpha, beta, and gamma radiation, which are emitted by radio- isotopes that may occur as an aerosol, be carried on particulate matter, or occur in a gaseous state. Alpha particles, consisting of two neutrons and two protons, are the least penetrating and the most ionizing form of radiation. They are emitted from the nu- cleus of radioactive atoms and transfer their energy at very...
