Match List-I with List-II and select the correct answer:
| List-I (Radioisotope) | List-II (Diagnostic use) |
| a. Arsenic-74 | 1. Activity of thyroid gland |
| b. Cobalt-60 | 2. Blood disorder |
| c. Iodine-131 | 3. Tumour |
| d. Sodium-24 | 4. Cancer |
A.
a-1, b-2, c-3, d-4
B.
a-4, b-3, c-1, d-2
C.
a-3, b-4, c-1, d-2
AnswerD.
a-4, b-3, c-2, d-1
Answer: Option C
Solution
Answer: Option C
Solution:
* Arsenic-74: This radioisotope is primarily used to locate tumors within the body.* Cobalt-60: Cobalt-60 is a strong radioactive source used in radiation therapy to treat cancer. It works by destroying cancerous cells.
* Iodine-131: This radioisotope is readily absorbed by the thyroid gland. Therefore, it's used to measure the activity of the thyroid gland and diagnose thyroid disorders.
* Sodium-24: This radioisotope is used to study blood disorders, particularly issues related to blood circulation.
Therefore, the correct matching is:
a - 3 (Arsenic-74 - Tumour)
b - 4 (Cobalt-60 - Cancer)
c - 1 (Iodine-131 - Activity of thyroid gland)
d - 2 (Sodium-24 - Blood disorder)
So, the correct answer is Option C: a-3, b-4, c-1, d-2
