The radio-isotope used in agriculture is:

• A. ${}_{15}{P}^{31}$
• B. ${}_{15}{P}^{32}$
• C. ${}_{11}N{a}^{23}$
• D. ${}_{11}N{a}^{24}$

Answer 1

Answer: (B)

${}_{15}{P}^{32}$

The radio-isotope used in agriculture is ${}_{15}{P}^{32}$. It is used to trace the assimilation of phosphorus by plants.
${}_{15}{P}^{32}$ is also used in treatment of leukemia. ${}_{11}N{a}^{24}$ is used to detect tumors and blood clots. ${}_{15}{P}^{30}\left(\beta \right)$ is used in treatment of skin diseases.
