Study type: Epidemiological study (observational study)

Cancer incidence and mortality and proximity to TV towers. epidem.

Published in: Med J Aust 1996; 165 (11-12): 601-605

Aim of study (acc. to author)

An ecological study was conducted in Australia to determine whether there was an increased cancer incidence and mortality in populations exposed to radiofrequency radiation from TV towers.

Further details

The data of cancer incidence and cancer mortality for three municipalities immediately surrounding the TV towers (inner area) were compared to the data of six adjacent municipalities (outer area).

Endpoint/type of risk estimation

Type of risk estimation: (relative risk (RR))

Exposure

Assessment

Exposure groups

Group Description
Reference group 1 outer area: municipalities in a distance of ≥ 4 km from a TV tower; power density: < 0.2 µW/cm²
Group 2 inner area: municipalities in a distance of < 4 km from a TV tower; power density: 0.2 - 8.0 µW/cm²

Population

Statistical analysis method: ( adjustment: )

Conclusion (acc. to author)

Brain cancer incidence and mortality were not increased. Elevated leukaemia incidence was observed for all ages (RR 1.24, CI 1.09-1.40), and for children (RR 1.58, CI 1.07-2.34). Leukaemia mortality was increased for children (RR 2.32, CI 1.35-4.01). An association between residential proximity to TV towers and increased incidence and mortality for childhood leukaemia was found.

Limitations (acc. to author)

Exposure was assessed for the municipality, not for the individual.
