Step by step solution

Step 1:Introduction

What exactly is microcurie? (unit) A microcurie is a unit of radioactivity measurement. A microcurie (Ci) is a non-SI (non-System International) radioactivity measurement unit. Given data is the activity of $14 C$ in a $70 - kg$ human body is estimated to be $3.7 kBq$ .

To find activity in microcuries

Step 2:Given data

Given data is The activity of $14 C$ in a $70 - kg$ human body is estimated to be $3.7 kBq$ .

To find activity in microcuries

Step 3:Explanation

$B v = 2.7 脳 10^{鈭� 11}$

$1 K B V = 2.7 脳 10^{鈭� 11} 脳 10^{3} Giuni$

$= 2.7 脳 10^{鈭� 8} cmis$

$l K B_{q} = 2.7 脳 10^{鈭� 8} 脳 10^{6} a = 2.7 脳 10^{鈭� 2} mino mini.$

$3.7 k B v = 3.7 脳 2.7 脳 10^{鈭� 2} = 0.099 mino arie$
