Question

What is the minimum amount of radiation protective material that must cover the bucky slot?

1. 1.0 mm Al equiv.
2. 0.5 mm lead equiv.
3. 0.5 mm Al equiv.
4. 0.25 mm lead equiv.

Answer 1

The minimum amount of radiation protective material that must cover the bucky slot is 1.0 mm Al equiv. Hence, option 1 is correct.

Step-by-step explanation:

The minimum amount of radiation protective material that must cover the bucky slot will depend on the type of radiation being emitted. In this case, we are given the options of 1.0 mm Al equiv, 0.5 mm lead equiv, 0.5 mm Al equiv, and 0.25 mm lead equiv. The term 'equiv' refers to the equivalent thickness of a specific material that provides the same level of radiation protection as the given material. To choose the minimum amount, we need to consider the material with the highest equivalent thickness. Therefore, the minimum amount of radiation protective material that must cover the bucky slot is 1.0 mm Al equiv.
