For skin cancer, which of the following can be used:
Correct answer: C. Phosphorous 32
- A. Iodine 131
- B. Carbon 14
- C. Phosphorous 32
- D. Carbon 12
Explanation
For skin cancer phosphorous-32 or strontium-90 may be used. Phosphorus-32 is a radioactive isotope of phosphorus. It can be used in the treatment of certain skin cancers, specifically cutaneous T-cell lymphoma (CTCL). P-32 is applied topically to the skin as a radioactive ointment or cream, where its beta radiation can target and treat the cancer cells on or near the skin's surface.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
