Question
Chapter 20, Problem 15RQ
Interpretation Introduction
Interpretation:
The radioactive element between barium
Concept Introduction:
Radionuclide is defined as an atom having excess of nuclear energy. This energy is released by the process of radioactive decay of nucleus.
With the decrease in the number of radionuclides, the intensity of the radiations also decreases.
