Q. 5.23 - An Introduction to General, Organic, and Biological Chemistry

Question

Match each property ( $\mathbf{1}$ to $3$ ) with its unit of measurement.

1. activity

2. absorbed done

3. biological damage

a. rad

b. mrem

c. mCi

d. Gy

Step-by-Step Solution

Answer

(part a) option $a$ match with option $2$.

(part b) option $b$ matches with option $3$.

(part c) option $c$ match with option $1$.

(part d) option $d$ match with option $2$$\left(2\right)$.

Step 1: Given information (part a)

The absorbed dose corresponds to the $mrem$

Step 2: Explanation (part a)

(part a) Rad: A $rad$ is a typical unit for measuring absorbed dosage.

The $SI$unit for absorbed dose is grey ($Gy$). Rad is the unit of measurement for absorbed dose.

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

$1 \mathrm{Gy}=100\mathrm{rad}$

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

Step 3: Given information (part b)

Biological harm is matched by $mCi$

Step 4: Explanation (part b)

(part b) $mrem$: millirems is a unit for measuring biological harm.

$rems = absorbed dose (rads ) \times factor$

The $rem$ is a popular unit for measuring biological harm, and the Sievert is the $SI$ unit.

As a result, option $b$ corresponds to option $3$.

Step 5: Given information (part c)

$\mu Ci$ corresponds to activity.

Step 6: Explanation (part c)

(part c) $\mu Ci$ : It is used to measure the activity of radiation.

Curie is a popular unit of activity measurement. The becquerel is the SI 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)

$Gy$ corresponds to the dose absorbed.

Step 8: Explanation (part d)

(part d) $Gy$:Gray is the $SI$ unit for absorption dosage ($Gy$).

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

The absorbed dosage is measured in $rad$.

The following is the relationship between grey and rad:

$1 \mathrm{Gy}=100\mathrm{rad}$

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