Radiofrequency Exposure Amongst Employees of Mobile Network Operators and Broadcasters

Area of Science:

• Occupational health
• Electromagnetic field exposure
• Telecommunications industry safety

Background:

• Limited data exists on radiofrequency (RF) field exposure for telecommunications workers installing/maintaining transmitters.
• The International Agency for Research on Cancer (IARC) classified RF exposure as a possible carcinogen, with inadequate occupational study evidence.
• There is a need for better evidence on potential adverse health effects from occupational RF radiation exposure.

Purpose of the Study:

• To assess personal RF field exposure levels in UK broadcasting and telecommunication industry employees.
• To provide reliable exposure estimates for epidemiological studies on workers exposed to RF radiation.

Main Methods:

• Utilized personal monitors and spot measurements (broadband survey meters) for RF exposure data.
• Collected daily work activity information via employee questionnaires.
• Categorized real-time personal data by site type (high, medium, low power, ground-level antennas).

Main Results:

• Riggers in radio and television broadcasting experienced significantly longer exposure periods than mobile operator colleagues.
• Highest personal RF exposures were identified for riggers working at broadcasting sites.
• The study confirmed the feasibility of conducting exposure surveys in these occupational groups.

Conclusions:

• Personal RF exposure varies significantly within the telecommunications industry, with broadcasting riggers facing the highest levels.
• The methodology employed is suitable for generating reliable exposure data for epidemiological research.
• Further research can now investigate potential health impacts associated with identified occupational RF exposure levels.
