To determine

The correct option for the statement “Which of the following types of radiation penetrate most deeply into the body?”.

Answer to Problem 3RAT

The correct option for the statement “Which of the following types of radiation penetrate most deeply into the body?” is option (c).

Explanation of Solution

Gamma radiations are electromagnetic radiations having high frequencies. They are chargeless radiations having no mass and having high energies. Because of no charge and mass, and high energy, gamma radiations have high penetrating power than other radiations.

Alpha radiations contain particles identical to helium nuclei. Therefore, alpha radiations have large-sized, positively charged particles that cannot easily penetrate materials.

Beta radiations are composed of negatively charged electrons or beta particles whose penetrating power is between gamma and alpha radiations.

Proton is a massive particle, which is a constituent of the nucleus. It has less penetrating power.

Conclusion:

Therefore, the correct option for the statement “Which of the following types of radiation penetrate most deeply into the body?” is option (c).
