Chapter 25, Problem 46PS

(a)

Interpretation Introduction

Interpretation:

The half-life of Strontium-90 has to be calculated.

Concept Introduction:

Radiocarbon dating: The dynamic equilibrium exists in all living organism by exhaling or inhaling, maintain the same ratio of 12C and 14C that takes in. when the living organism dies, the intake of 14C stops and it’s the ratio no longer exhibits equilibrium; undergoes radioactive decay.

Half-life period: The time required to reduce to half of its initial value.

Formula used to calculate half-life:

t1/2=0.693kwhere,kis rate constant.(or)ln[N]t- ln[N]0= -kt

(b)

Interpretation Introduction

Interpretation:

The time required for the activity of sample to drop to 1% of the initial value has to be calculated.
