Textbook Problem

Strontium-90 and radon-222 both pose serious health risks. 90Sr decays by β-particle production and has a relatively long half-life (28.9 years). Radon-222 decays by α-particle production and has a relatively short half-life (3.82 days). Explain why each decay process poses health risks.

Interpretation Introduction

Interpretation: Health risks produced by decay process of strontium- 90 and radon- 222 are to be stated.

Concept introduction: The Sr do not possess radioactive properties but its isotope 90Sr 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 health risks produced by decay process of strontium- 90 and radon- 222 .

Explanation

Explanation

Decay of both strontium- 90 and radon- 222 is harmful but the radioactive nuclide of Sr possess greater health hazard.

The radioactive nuclide 90Sr is most harmful when it is ingested with water, food and in case of inhalation also
