Q. 5.24 - An Introduction to General, Organic, and Biological Chemistry

Question

Match each property ( $1 to 3$ ) with its unit of measurement.

$1.$ activity

$2.$ absorbed dose

$3.$ biological damage

a. $mrad$

b. $gray$

c. $becquerel$

d. $Sv$

Step-by-Step Solution

Answer

(part a) option $\left(a\right)$ matches with $\left(2\right)$ option .

(part b) option $\left(b\right)$ matches with $\left(2\right)$ option .

(part c) option $\left(c\right)$ matches with $\left(1\right)$ option .

(part d) option $\left(d\right)$ matches with $\left(3\right)$ option .

Step 1: Given information (part a)

$mrad$ corresponds to the dose absorbed.

Step 2: Explanation (part a)

(part a) $mrad$: A typical unit for measuring absorbed dose is the $mrad$.

$1$ $rad$ equals $1,000$ $mrad$.

$Gray$ is the $SI$ unit for absorbed dosage ($Gy$).

The following is the relationship between $grey$ and $rad$:

$1Gy=100\mathrm{rad}$

As a result, option $\left(a\right)$ corresponds to option $\left(2\right)$.

Step 3: Given information (part b)

$gray$ corresponds to the dosage absorbed.

Step 4: Explanation (part b)

(part b) $Gy\left(gray\right)$Sl unit for absorbed dosage is $gray$$\left(Gy\right)$.

The $rad$ is a popular unit for measuring absorbed dosage.

The absorbed dose is measured in $rad$.

The following is the relationship between $gray$ and $rad$:

$1Gy=100\mathrm{rad}$

As a result, option $\left(b\right)$ corresponds to option $\left(2\right)$.

Step 5: Given information (part c)

$becquerel$ corresponds to activity.

Step 6: Explanation (part c)

(part c) $becquerel$: is a unit of measurement for radiation activity.

$Curie$ is a popular unit of activity measurement. The $becquerel$ is the $Sl$ unit for activity.

The following is the relationship between Curie and Becquerel:

$1\mathrm{Ci}=3.7\times {10}^{10} \mathrm{Bq}$

As a result, option $\left(c\right)$ corresponds to option $\left(1\right)$.

Step 7: Given information (part d)

Biological harm matches $Sv$.

Step 8: Explanation (part d)

(part d) $sievert \left(Sv\right)$: is a biological damage measurement unit.

The $sievert$ is a unit of measurement for biological harm.

$1 sievert =100 rem$

As a result, option $\left(d\right)$ is compatible with option $\left(3\right)$.
