In QC testing, receptor exposure is commonly measured in which unit?

Explanation:
Receptor exposure refers to the dose that reaches the image receptor, which is a very small amount. Using microgray (µGy) keeps the numbers in a practical range and matches how exposure at the receptor is reported in QC protocols. A gray would be far too large for receptor-level doses, and centigray or milligray would yield bigger values that aren’t the standard way QC exposures are expressed. So µGy is the appropriate unit for receptor exposure in QC testing.
