alleryWhich radioisotope is used to diagnose and treat anaemia?
ARadio-cobalt (Co-60)
BRadio-iodine (I-131)
CRadio-iron (Fe-59)
DRadio-carbon (C-14)
Answer & Solution
Correct answer: C. Radio-iron (Fe-59)
1. Anaemia involves a deficiency related to iron in blood.
2. Radio-iron (Fe-59) is used to diagnose and treat anaemia.
3. Radio-iodine treats goitre; radio-cobalt treats cancer.
4. Radio-carbon is used for dating, not anaemia.
