Question

Which of the following is used in the treatment of blood cancer?
A. $ {1^{131}} $
B. $ {P^{32}} $
C. $ Rn $
D. $ {I^{127}} $

Answer 1

Hint: The element phosphorus in its radioactive form. It's used to mark DNA and proteins in the lab. It was previously used to treat polycythemia vera, a blood condition, and certain kinds of leukaemia, but it is no longer widely used. $ Phosphorus - 32 $ emits radiation that destroys a cell's DNA, potentially causing the cell to die.

Complete answer:
 $ Phosphorus - 32{\text{ }}\left( {32P} \right) $ is a phosphorus isotope that is radioactive. $ Phosphorus - 32 $ has 15 protons and 17 neutrons in its nucleus, one more than the most prevalent phosphorus isotope $ phosphorus - 31 $ . $ Phosphorus - 32 $ is only found in trace amounts on Earth due to its short half-life of 14 days and quick degradation.
Phosphorus is abundant in many organic molecules, therefore $ Phosphorus - 32 $ can be used to trace phosphorylated compounds (for example, in elucidating metabolic pathways) and radioactively mark DNA in medicine, biochemistry, and molecular biology.
 $ Phosphorus - 32 $ can be tracked from outside the body to pinpoint the location of potentially cancerous tumours. $ Phosphorus - 32 $ emits radiation that can be used for both medicinal and diagnostic purposes. The use of $ {}^{32}P - chromic{\text{ }}phosphate $ as a prospective chemotherapeutic treatment for disseminated ovarian cancer has been investigated. In this case, the therapeutic effect is due to the long-term damaging consequences of beta radiation from $ Phosphorus - 32 $ accumulating in malignant cells. $ Phosphorus - 32 $ is commonly used to identify and treat cancer, particularly in the eyes and skin.
So, the correct option is: (B) $ {P^{32}} $ .

Note:
In plant sciences, $ Phosphorus - 32 $ is used to follow a plant's fertiliser intake from the roots to the leaves. The $ Phosphorus - 32 $ -labeled fertiliser is applied to the plant hydroponically or through water in the soil, and the phosphorus utilisation may be calculated using the released beta radiation.
