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.
