What is an advantage of gamma ray over x-ray?

• A. Portability
• B. Higher energy
• C. Lower cost
• D. Better image quality

Answer: (A)

Portability is the main advantage here: gamma-ray radiography typically uses a sealed radioactive source that is self-contained and does not require an external power supply. That means the imaging device can be moved to the inspection site and operated with relatively simple shielding, making field use practical. X-ray systems, on the other hand, rely on a high-voltage generator and larger, heavier equipment, which makes them much less portable. While energy levels, cost, and image quality depend on specific sources and setups, the ability to deploy a gamma-ray source on-site without a bulky power setup is the clearer practical edge.
