Chapter 19, Problem 66QAP

Interpretation Introduction

Interpretation:

Why gamma particles show more penetration than alpha particles and damage the organism should be explained. The radiation which is more effective in ionization of the biomolecules should be determined.

Concept Introduction:

The radioactive decay is the decay of the unstable nuclide to the stable nuclide.

If a decay results in lower energy state and emission of gamma ray photon takes place, the process is called gamma decay.

Alpha decay is the decay in which mass number is decreases by 4 and atomic number is decreases by two and emission of He atom takes place.
