Consider the table below that summarizes the types of materials that can block the 3 different types of radiation.

Material
1
2
3
Lead Stopped Stopped Stopped
Cloth Not stopped Stopped Stopped
Aluminum foil Not stopped Stopped Stopped
Wood Not stopped Stopped Stopped
Paper Not stopped Stopped Not stopped
Thick concrete Stopped Stopped Stopped

Based on the table, at which numbered spot in the table does each type of radiation belong?
1 = beta; 2 = alpha, 3 = gamma
1 = alpha; 2 = beta, 3 = gamma
1 = beta; 2 = gamma, 3 = alpha
1 = gamma; 2 = alpha, 3 = beta

1 = gamma; 2 = alpha; 3 = beta

Explanation: Column 1 is only stopped by dense materials (lead, thick concrete) — characteristic of gamma. Column 2 is stopped even by paper — characteristic of alpha. Column 3 is stopped by foil/wood/cloth but not paper — characteristic of beta.
