The relative standard of counting rate σ R R = M − 1 / 2 is to be proved. Concept introduction: The counting rate is calculated by the following formula- R = M t …………… (1) And standard deviation for counting rate is given as- σ R = σ M t …………… (2) Standard deviation is- σ M = M …………… (3) Relative standard deviation is for counting rate = σ R R …………… (4) Where, M = counts t = time σ M = standard deviation for M σ R = relative standard deviation

Chapter 32, Problem 32.12QAP
Interpretation Introduction

Interpretation:

The relative standard of counting rate σRR=M1/2 is to be proved.

Concept introduction:

The counting rate is calculated by the following formula-

R=Mt …………… (1)

And standard deviation for counting rate is given as-

σR=σMt …………… (2)

Standard deviation is-

σM=M …………… (3)

Relative standard deviation is for counting rate = σRR …………… (4)

Where,

M = counts

t = time

σM = standard deviation for M

σR = relative standard deviation
