Abstract

BACKGROUND: In the studies investigating the potential health effects of occupational exposure to electromagnetic fields (EMF), the key problem is the assessment of workers' exposure. Electromagnetic fields exposure assessment requires determining maximum EMF levels, for the acute effect, and the dose absorbed, for the cumulative effect. A study was undertaken to determine EMF exposure in workers at broadcasting centers (BCs) in Poland. It was the first part of a comprehensive project on health effects of occupational exposure to EMF. MATERIAL AND METHODS: The study was conducted in 4 selected BCs. Spot measurements of electric field strength (E), and the results of E measurements that were made in the past for occupational hygiene assessments, were used for determining workers' exposure to electric field. The parameters considered were the maximum E value (E), the weighted average E value (E) and the E lifetime dose (E). RESULTS: In the group of workers examined, the E values did not exceed 16.7 V/m for Emax (the occupational exposure limit (OEL) for work shift in Poland is 20 V/m), 2.9 V/m for E and 1 500 000 (V/m)×h for E. CONCLUSIONS: In view of the lack of dosimetry data, a retrospective assessment of BC workers' exposure to very high frequency and ultra-high frequency EMF was conducted, which made it possible to estimate EMF lifetime dose for the workers. Since the EMF exposure levels at BCs did not exceed the admissible values, they can be considered safe to the workers' health, according to the approach used for developing OELs for EMF exposure.

Main findings

Across workers assessed at 4 broadcast centers, measured electric field strengths did not exceed 16.7 V/m for Emax (Polish OEL for work shift: 20 V/m), 2.9 V/m for weighted average E, and 1,500,000 (V/m)×h for lifetime dose. The authors conclude exposures did not exceed admissible values under the OEL-based approach used.

Outcomes measured

  • Occupational electric field strength exposure (E)
  • Maximum electric field strength (Emax)
  • Weighted average electric field strength (E)
  • Lifetime electric field dose (E)

Limitations

  • Conducted in 4 selected broadcast centers (selection may limit generalizability)
  • Retrospective assessment noted due to lack of dosimetry data
  • Exposure assessment focused on electric field strength; other EMF metrics not described
