Why does the Gamma-Ray industrial radiography test typically require a significantly longer exposure time compared to X-ray testing for the same material thickness?
Verified Solution4 OptionsUpdated: October 2026👁️1 View
Share:
- 1Gamma rays inherently possess lower penetrating power than standard X-rays
- 2The photon emission rate (intensity) of commercial gamma-ray sources is generally lower than X-ray tubes✓
- 3Gamma rays interact chemically with films and do not require any true exposure time
- 4Gamma rays are strictly confined to evaluating surface-level defects only
Correct answer
The photon emission rate (intensity) of commercial gamma-ray sources is generally lower than X-ray tubes
