Correct Answer - Option 1 :
P-32
Concept:
Isotopes:
- Isotopes are nuclides that have the same atomic number but different mass numbers.
- Since they have the same number of protons, they are atoms of the same element.
- Have identical chemical properties.
- Due to differences in mass numbers, they have different physical properties and rates of reactions.
Eg: Protium (1H1), deuterium (2H1), and tritium (3H1) are isotopes of Hydrogen; 35Cl17 and 37Cl17 are isotopes of Chlorine.
Explanation:
Application of Isotopes in Medical diagnosis:
Various isotopes find application in medical treatment. Some examples are given below:
Isotope |
Use |
74As |
- For locating brain tumours
|
32P
|
- For detecting skin cancer
- For the treatment of blood cancer.
|
58Co
|
- For determining the uptake of vitamin B12
|
51Cr
|
- For determining the volume of red blood cells and total volume of blood.
|
59Fe
|
- For measuring the rate of formation and lifetime of red blood cells.
|
60Co |
- To destroy cancerous cells in deep-seated growths in the body.
|
131I |
- Destroy the cancerous thyroid cells.
|
90Sr |
- For the treatment of corneal cancer.
|
Hence, the
isotope used in the treatment of blood cancer is P-32.
