In the example, what unit is used to express beam intensity?

Explanation:
Beam intensity for X-ray beams in diagnostic imaging is a measure of how much radiation dose is delivered per unit area, and those doses are typically small. Because of that, the practical unit to express this quantity is microgray (μGy), a subunit of the gray that keeps numbers convenient and directly tied to absorbed dose. One gray is a large amount of energy deposited per kilogram, so using μGy makes the reported beam intensity easy to compare and work with in safety and exposure calculations. The other options are less appropriate: a whole gray would imply a much larger dose than typical imaging beams, milligray is still larger than common diagnostic levels, and nanogray would be far too small to represent practical beam intensity.
