Chapter 16, Problem 40CI
Interpretation Introduction

(a)

Interpretation:

To write the balanced nuclear equation for the decay of Ra-226.

Concept Introduction:

According to the law of conservation of mass the sum of the atomic numbers and the sum of the atomic mases on the reactant side must be equal to the product side.

Interpretation Introduction

(b)

Interpretation:

To write the balanced nuclear equation for the decay of Rn-222.

Concept Introduction:

According to the law of conservation of mass the sum of the atomic numbers and the sum of the atomic mases on the reactant side must be equal to the product side.

Interpretation Introduction

(c)

Interpretation:

If a room contains 24,000 atoms of radon-222, to find the number of atoms of radon-222 remain after 15.2 days.

Concept Introduction:

Radioactive decay equation:

  N(t) = No(12) tt 1/2

where No is the initial activity, N(t) is the activity at time t, and t1/2is the half life of the radioactive substance.

Interpretation Introduction

(d)

Interpretation:

Suppose a room has a volume of 72,000 L. If the radon level is the maximum allowed (4 pCi/L), to find the number of alpha particles that are emitted from Rn-222 in one day. (1 Ci = 3.7×1010dps)

Concept Introduction:

An arithmetical multiplier which is used for converting a quantity expressed in one unit into another equivalent set of units is said to be conversion factor.

The conversion factor used to convert Ci to pCi is as follows:

  2.703×1011Ci = 27 pCi
