X-rays are widely used as a diagnostic tool in medicine because of its:
Correct answer: C. High penetrating power
- A. Particle property
- B. Cost of X-ray unit is low
- C. High penetrating power
- D. It is not electromagnetic waves
Explanation
X-rays are a type of electromagnetic radiation with high frequency and energy, which grants them significant penetrating power. This characteristic is essential for medical diagnostics, as it allows X-rays to pass through the body and produce images of bones and other internal structures. This ability to create detailed images is why they are widely used in medicine.Options A and D are incorrect because X-rays are electromagnetic waves, not particles. Option B is misleading as the cost of X-ray machines is not low; their diagnostic utility justifies their expense.

About Biological and Medical Uses of Radiation
Radiation in medicine includes X-rays and gamma rays for imaging, radioactive tracers for diagnosis, and controlled radiation for destroying cancerous tissue. The topic also covers CT scans, PET imaging, radiotherapy, sterilisation, half-life and dosage, alongside biological damage, shielding and the need to balance diagnostic or therapeutic benefit against exposure.
