. Cohah-62 ( C 27 62 o ) is a radionuclide with a half-life of 1.5 minutes. What fraction of an initial sample of Co-62 will remain after 6 mm?

Interpretation Introduction

Interpretation:

Interpret the remaining amount of sample after 6 minute if the half life is 1.5 minute.

Concept Introduction:

Half life is the measurement of time required for the conversion of half of the reactant to product and can be indicated as t1 / 2.

A reactant reacts to produce product in particular duration of time whereas if time to be recorded for the completion of half of the reaction then it gets denoted by t1 / 2.

Explanation

For determining the amount of sample remaining after 6 minutes.

N /N01 /2T /Th

Where, N is concentration of sample left.

N0 is original concentration of sample.

T h is half life.

N /N0
