Question:
Commercial gamma radiation is NOT used for:
Commercial gamma radiation is NOT used for:
Show Hint
Gamma = Great for Solids (plastic/metal); Bad for Liquids (chemical damage).
Updated On: May 15, 2026
- Swab
- Metal foil
- Heat label liquid
- Syringes
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Ionizing radiation, such as gamma rays from Cobalt-60, is a "cold" sterilization method used for various medical supplies.
Step 2: Meaning
Sterilization must be compatible with the physical and chemical properties of the material to avoid degradation.
Step 3: Analysis
Gamma radiation is excellent for dry items like swabs, syringes, and metal foils. However, it can cause chemical changes in liquids, such as the generation of free radicals or the breakdown of active pharmaceutical ingredients.
Step 4: Conclusion
Due to its potential to alter the chemical composition of liquids, gamma radiation is not suitable for heat-labeled or aqueous liquids. Final Answer: (C)
