Chapter 18, Problem 10RQ

Interpretation Introduction

Interpretation: The factors on which biological effect of a particular source of radiation depends are to be listed. The reason for greater danger associated with ${}^{90}\text{Sr}$ in comparison to ${}^{\text{85}}\text{Kr}$ and more damage to an organism by alpha particles than gamma particles is to be stated. The type of radiation more effective at promoting the ionization of biomolecules is to be stated.

Concept introduction: The $\text{Sr}$ do not possess radioactive properties but its isotope ${}^{\text{90}}\text{Sr}$ have high radioactive properties and it undergo beta decay. It causes damage to humans as well as environment. Radon- $222$ decays by alpha particle production and also possesses health risks.

To determine: The factors on which biological effect of a particular source of radiation depends, reason for greater danger associated with ${}^{90}\text{Sr}$ in comparison to ${}^{\text{85}}\text{Kr}$ and more damage to an organism by alpha particles than gamma particles and the type of radiation more effective at promoting the ionization of biomolecules.
