Chapter 24: Q24.61 P (page 1104)

A $3.6$ -kg laboratory animal receives a single dose of data-custom-editor="chemistry" ${8.92×10}^{-4}$ Gy.
(a) How many rads did the animal receive?
(b) How many joules did the animal absorb?

Short Answer

Expert verified

$\begin{array}{l} a.0.0892rad \\ {b.3.2112x10}^{-3} J \end{array}$

Step by step solution

Gray and Rad

Gray is the metric unit and Rad is the CGS unit of radiation. The relation between them is as shown below:

1 Gy = 100 rd

Explanation

The SI unit of such energy absorption is the gray (Gy) which is equal to_{$1 \frac{J}{kg}$}of body tissue. A more widely used unit is the rad (radiation-absorbed dose), which is one-hundredth as much

_{$1rad= \frac{0.01.J}{kg} =0.01Gy$}

To calculate the rads the animal receive, we just need to convert the given value to rads.

a. rads

_{$({8.92×10}^{-4} Gy) (\frac{1rad}{0.01Gy}) =0.0892rad$}

b. Energy in Joules

_{$(0.0892rad) (\frac{\frac{0.01.J}{kg}}{1rad}) {(3.6kg)=3.2112×10}^{-3} J$}
