Question
Chapter 19, Problem 63E
Interpretation Introduction
Interpretation: Between the release of a radioactive nuclide of Sr and a radioactive nuclide of Xe, the greater health hazard for the environment is to be stated. Reason for the importance of chemical properties of a radioactive substance in assessing its potential health hazard is to be stated.
Concept introduction: Sr does not possess radioactive properties but its isotope 90Sr has high radioactive properties and it undergoes beta decay. It causes damage to humans as well as to the environment.
To determine: The more hazardous nuclide and importance of chemical properties of radioactive substance in assessing its potential health hazard.
