Question
Explain why gamma radiation is often chosen for sterilising medical equipment.
Answer
Gamma radiation is chosen for sterilising medical equipment because it has high penetration power, allowing it to kill bacteria and viruses without damaging the equipment. Its ability to penetrate packaging means that items can be sterilised without needing to be opened.
Explanation
This question evaluates the student's ability to explain the advantages of gamma radiation in a specific context. It requires an understanding of both the properties of gamma radiation and its practical applications in medicine.
Common mistake
Misunderstanding Radiation Types
Students often confuse the uses of beta and gamma radiation in thickness monitoring, thinking they are interchangeable.
To fix this, students should study the properties of beta and gamma radiation, focusing on their penetration abilities and ionising power, to understand why one is preferred over the other for specific applications.
