The MOST appropriate isotope for the treatment of thyroid gland is

Correct answer: B. Iodine-131.

  • A. Cobalt-60.
  • B. Iodine-131.
  • C. Carbon-14.
  • D. Strontium-90.

Explanation

The correct answer is Iodine-131. This isotope is highly effective in the treatment of thyroid-related conditions because the thyroid gland naturally accumulates iodine, allowing the radioactive isotope to target and treat the affected gland directly. Cobalt-60 is more commonly used in external beam radiotherapy for various cancers. Carbon-14 is utilized for dating and research purposes. Strontium-90 targets bone tissues due to its similarity to calcium, making it unsuitable for thyroid treatment.
