Question

1. what type of radiation particles were the most biologically dangerous?

a. alpha
b. beta
c. gamma
d. delta

Explanation:

Gamma radiation has high - energy photons and can penetrate deeply into the body, causing damage to internal organs and cells. Alpha particles are large and can be stopped easily outside the body but are dangerous if ingested or inhaled. Beta particles have moderate penetration and ionizing ability. There is no "delta" radiation particle in common radiation types. Gamma radiation is generally considered the most biologically dangerous among the common types due to its high penetration and ability to cause widespread damage to living tissue.

Answer:

c. gamma
