Answer
Explanation:
Step1: Recall radiation - blocking properties
Alpha radiation is the least penetrating and can be stopped by a sheet of paper, cloth, aluminum foil, and wood. Beta radiation is more penetrating than alpha and can be stopped by aluminum foil, but not by paper. Gamma radiation is the most penetrating and requires thick materials like lead or thick concrete to stop it.
Step2: Analyze the table
Looking at the table, radiation type 2 is stopped by cloth, aluminum foil, wood, and paper, so it is alpha radiation. Radiation type 3 is stopped by cloth, aluminum foil, and wood but not by paper, so it is beta radiation. Radiation type 1 is only stopped by lead and thick concrete, so it is gamma radiation.
Answer:
1 = gamma; 2 = alpha, 3 = beta
