The presented algorithm has proven to facilitate the anamnestic procedure to estimate the lifetime UVR dose of exposed outdoor workers. With a recently developed computer-based tool, standardized interviews of suspected workers with NMSC become simple. UVR dose as well as matching of requirements for recognition as an occupational disease in an individual worker are calculated automatically. Furthermore, with ongoing on-the-job measurements, a database is created to continuously adjust the algorithm's reference values for the various UVR-exposed occupations. In addition, a job exposure matrix UVA/UVB is created as a pivotal tool for improved health and safety of outdoor workplaces and prevention of occupational actinic damage to the skin.

Solar occupational UV exposure is a major determinant of incident SCC. Our findings indicate that prevention strategies should be further expanded to the occupational setting.

Skin cancer prevention strategies should be expanded to the occupational setting.
