Outdoor work and solar radiation exposure: Evaluation method for epidemiological studies

Area of Science:

• Environmental Health
• Occupational Health
• Radiation Biology

Background:

• Excessive solar radiation (SR) exposure poses known health risks.
• The Sun is the primary source of optical radiation, including infrared (IR), ultraviolet (UV), and visible light.
• Outdoor workers experience significant SR exposure, yet detailed individual exposure histories are rarely documented.

Purpose of the Study:

• To develop and validate a new method for evaluating cumulative SR exposure.
• To integrate subjective and objective data for a comprehensive assessment of lifetime SR exposure.
• To provide a tool for epidemiological studies investigating SR-related health effects.

Main Methods:

• A novel method integrating subjective (questionnaire) and objective (online databases, personal UV dosimeters) data was developed.
• Subjective data was collected via interviewer-administered questionnaires.
• Objective data included environmental SR data from online databases and personal UV dosimetry measurements.

Main Results:

• The questionnaire was tested on 58 volunteers.
• Environmental SR data was gathered for three Italian locations in 2012.
• Personal UV exposure was measured in 6 fishermen, and a mathematical algorithm was created to integrate all data.

Conclusions:

• The proposed method can be utilized in epidemiological studies.
• It allows for evaluating correlations between SR exposure and biological effects.
• The method helps to identify personal and environmental factors influencing SR exposure levels.
