Question
Chapter 2, Problem 2.68AP
Summary Introduction
To determine:
The quantity measured by the unit millirem.
Introduction:
Radioactivity is the emission of subatomic particles from the unstable nucleus of the isotope. The unstable nucleus disintegrates and loses energy which affects the biological system of the living organisms. The radiations having high energy cause more damage as compared to the low energy radiations.
