Question

Describe the structure and properties of the 3 types of radiation (please list the 3 types too!!) :)

Answer 1

Answer:

Radiation can be absorbed by substances in its path. For example, alpha radiation travels only a few centimetres in air, beta radiation travels tens of centimetres in air, and gamma radiation travels very large distances

Explanation:

Alpha radiation

Alpha radiation is the least penetrating. It can be stopped (or absorbed) by a human hand.

Beta radiation

Beta radiation can penetrate air and paper. It can be stopped by a thin sheet of aluminium.

Gamma radiation

Gamma radiation is the most penetrating. Even small levels can penetrate air, paper or thin metal. Higher levels can only be stopped by many centimetres of lead or many metres of concrete.
