. Each of the following isotopes has been used medically for the purpose indicated. Suggest reasons why the particular element might have been chosen for this purpose.

a. cobalt-57, for study of the body’s use of vitamin B12

b. calcium-47, for study of hone metabolism

c. iron-59, for study of red blood cell function

d. rncrcury-197, for brain scans before CAT scans became available

Interpretation Introduction

(a)

Interpretation:

Interpret the reason for the use of cobalt-57 for studying body’s requirement of vitamin B12.

Concept Introduction:

Majorly 99% of body mass composed of 6 elements such as oxygen, carbon, hydrogen, nitrogen, calcium and phosphorus while the 5 elements are present in 0.85 % of body.

The elements are required for proper functioning of body as some are requried as catalyst or some are required as oxidasing or reducing agent.

Explanation

RBC contains cobalt element in it which helps in maintaining the size of it. Body requires vitamin B12 for increasing the RBc’s count...
