Question
Chapter 19, Problem 19.24P
Interpretation Introduction
Interpretation:
To calculate how many years ago naturally occurring uranium contained 3%
Concept Introduction:
Half-life is defined as the time taken for a radioactive substance to decay to half of its original amount.
When two percentages of a radioactive substance in naturally occurring ore are given, one of the past and the one of present, then the ratio of old percentage : present percentage gives a fraction.
This fraction can be used to calculate how many half-lives have elapsed from the formula:
This n when multiplied by the half life provides the age of the substance.
