[A literature analysis of power frequency electric field testing data]

Area of Science:

• Environmental Health
• Occupational Safety
• Electromagnetics

Background:

• Power frequency electric fields are recognized occupational hazards.
• Extensive literature exists on electric field testing data.
• Understanding exposure levels is crucial for workplace safety.

Purpose of the Study:

• To analyze existing literature on power frequency electric field testing data.
• To provide insights and recommendations for current testing methodologies.
• To evaluate the significance of electric field exposure in occupational settings.

Main Methods:

• Literature review of power frequency electric field testing data.
• Inclusion of 306 articles and 193 valid testing datasets.
• Statistical analysis using Mann-Whitney and Wilcoxon W tests.

Main Results:

• Data classified relative to occupational exposure limits (1.25, 2.5, and 5 kV/m).
• Significant structural differences in testing data between power and non-power facility groups (P<0.05).
• Most workplace data (excluding high-voltage facilities) falls well below exposure limits.

Conclusions:

• Power frequency electric field radiation is extensive but generally poses little harm in most workplaces.
• Current testing for power frequency electric fields appears excessive.
• Recommendations for refining testing strategies are needed.
