OBJECTIVE: To
determine whether there is an increased cancer incidence and mortality in
populations exposed to radiofrequency radiations from TV towers. DESIGN: An
ecological study comparing cancer incidence and mortality, 1972-1990, in nine
municipalities, three of which surround the TV towers and six of which are
further away from the towers. (TV radiofrequency radiation decreases with the
square of the distance from the source.) Cancer incidence and mortality data
were obtained from the then Commonwealth Department of Human Services and
Health. Data on frequency, power, and period of broadcasting for the three TV
towers were obtained from the Commonwealth Department of Communications and the
Arts. The calculated power density of the radiofrequency radiation in the
exposed area ranged from 8.0 microW/cm2 near the towers to 0.2 microW/cm2 at a
radius of 4km and 0.02 microW/cm2 at 12 km. SETTING: Northern Sydney, where
three TV towers have been broadcasting since 1956. OUTCOME MEASURES: Rate ratios
for leukaemia and brain tumour incidence and mortality, comparing the inner with
the outer areas. RESULTS: For all ages, the rate ratio for total leukaemia
incidence was 1.24 (95% confidence interval [CI], 1.09-1.40). Among children,
the rate ratio for leukaemia incidence was 1.58 (95% CI, 1.07-2.34) and for
mortality it was 2.32 (95% CI, 1.35-4.01). The rate ratio for childhood
lymphatic leukaemia (the most common type) was 1.55 (95% CI, 1.00-2.41) for
incidence and 2.74 (95% CI, 1.42-5.27) for mortality. Brain cancer incidence and
mortality were not increased. CONCLUSION: We found an association between
increased childhood leukaemia incidence and mortality and proximity to TV
towers.
