Textbook Problem

Arrange the following according to their ability to act as radiation shields, with the best first and worst last. Explain your ordering in terms of how radiation loses its energy in matter.

(a) A solid material with low density composed of low-mass atoms.

(b) A gas composed of high−mass alums.

(c) A gas composed of low−mass atoms.

(d) A solid with high density composed of high−mass atoms.

To determine

The arrangement of the following according to their ability to act as radiation shields, with the best first and worst last.

(a) A solid material with low density composed of low-mass atoms.

(b) A gas composed of high-mass atoms.

(c) A gas composed of low-mass atoms.

(d) A solid with high density composed of high-mass atoms.

Explanation

Introduction:

The radiation is released by the radioactive particle releases energy.

As from the principle of conservation of energy and the momentum the energy will transfer to an object which is less massive in a collision and the radiation interaction with atom or molecules of the medium is used as radiation shielding that depends upon the density and size of the atoms. In other words,

The distance travelled in a material or range of the radiation which is ionizing in nature is directly in relation with the charge of the particle which gets emitted and its energy, with the particle having greater charge and lower energy then they will have shorter ranges.

Thus, the substance with high density will provide the best shielding for radiations.

Hence, the given parts can be arranged with the best first and worst last in below manner...
