Chapter 19, Problem 33QAP

Interpretation Introduction

Interpretation:

Interpret the instrument used for measure the rate of decay of radioactive material and instrument for measure the rate of decay of radioactive material by sensing the light.

Concept Introduction:

Radioactive decay is the decaying of an element to smaller nuclide by releasing either alpha or beta particle. In alpha decay, an alpha particle with mass 4m and electron 2e removed from nuclide while in beta decay two type of decay are possible beta (+) and beta (-).
