An approximation of occupational lifetime UVR exposure: algorithm for retrospective assessment and current measurements.

Background: Since non-melanoma skin cancer (NMSC) has been adopted as an occupational disease in Germany, in any single suspected case a retrospective estimation of the outdoor workers' occupational UVR exposure is mandatory.

Objective: The aim of this study was to introduce the recent German standard procedure as a mathematical algorithm for retrospectively estimating individual occupational UVR lifetime exposure. In addition, to present results of exemplary on-the-job UVR dosimetry measurements on outdoor workers during their various occupational activities.
