Chapter 24, Problem 24.60P

(a)

Interpretation Introduction

Interpretation:

Number of $Rads$ (Dose) received by $135\text{ lb}$ person has to be determined using the given data.

Concept Introduction:

Radiation Dose is the dose quantity that explains the effects of ionizing radiation. It describes the quantity of radiation energy that is absorbed by a matter.

  $Dose\text{ = }\frac{Energy\left(Joules\right)}{Weight\left(kg\right)}$

The units commonly used to measure dose are $\text{gray }\left(Gy\right)\text{ and rad}.$

  $\begin{array}{l}\text{1 Gy = 1 J/kg}\\ \\ \text{1 rad = 0}\text{.01 J/kg = 0}\text{.01 Gy}\end{array}$

Unit conversion:

  $1\text{ kg = 2}\text{.205 lb}$

(b)

Interpretation Introduction
