What is the total occupational dose for a radiographer who received a dose of 7.5 mSv while working in an x-ray dept.?

The total occupational dose for a radiographer in this scenario is represented by the dose they received while working, which is 7.5 mSv. In this context, occupational dose refers specifically to the amount of radiation exposure the individual has accumulated during their professional duties.

When considering radiation doses, it is crucial to focus on the specific amount received during the work period without any additive factors unless specified. In this case, there are no additional doses or contributions from other sources mentioned in the question, making the 7.5 mSv the only relevant value.

Thus, the total occupational dose is accurately reflected as 7.5 mSv since it is the direct measurement of what the radiographer was exposed to during their work in the x-ray department. Understanding this concept is essential for radiographers in monitoring their exposure and ensuring safety protocols are followed.
