Employers provide records of employment episodes, occupational exposure to ionising radiation and some personal identifying data.

Details
In the early days of the UK nuclear industry, most radiation workers only had a single employment, but in recent years more workers are having multiple employments as radiation workers, either directly with the employers who manage the sites or indirectly via contracting companies.
It is very important that all the occupational radiation doses received by a worker are recorded on the National Registry for Radiation Workers (NRRW), so as to avoid bias in the estimates of risk from the study caused by missing doses.
