Abstract

Overview

The research aims to evaluate prenatal exposure to radiofrequency radiation (RFR) from telecommunication sources using various assessment methods.

Materials and Methods

• A study involving 1228 mother-infant pairs from the MOCEH study, with enrollment at ≤ 20 weeks of pregnancy.
• Multiple methods including a mobile phone questionnaire, operator data logs, and a personal exposure meter (PEM) were utilized.
• The EME Spy 100 PEM measured RFR among 269 pregnant women from November 2007 to August 2010.
• Operators' log data were obtained from 21 participants.

Findings

The study found significant correlations in mobile phone use data between operators' log and self-reported questionnaires, with moderate to high correlation values.

• Significantly high correlations for average calling frequency and time per day from self-reported data and operators' logs.
• Poor correlation between self-reported questionnaire and PEM data, but high correlation between operators' logs and PEM data.

Conclusion

The study concludes that multiple assessment methods improve accuracy in evaluating prenatal radiofrequency exposure. The multi-method approach is recommended for future environmental exposure assessments.
