Cancer incidence near radio and television transmitters in Great Britain II. All high power transmitters.
A small area study of cancer incidence, 1974-1986, near 20 high power television (TV) and frequency modulation (FM) radio transmitters in Great Britain was carried out to place in context the findings of an earlier study around the Sutton Coldfield transmitter.
The national database of postcoded cancer registrations was used with population and socioeconomic data from the 1981 census.
Cancers examined were adult leukemias, skin melanoma, and bladder cancer, following the findings in the earlier study of significant declines in risk of these cancers with distance from the Sutton Coldfield transmitter.
Childhood leukemia and brain cancer were also examined.
Statistical analysis was performed for all transmitters combined, four overlapping groups of transmitters defined by their transmission characteristics, and for all transmitters separately.
There were 3,305 adult leukemia cases from 0-10 km (observed/expected (O/E) ratio=1.03,95% confidence interval (CI) 1.00-1.07).
A decline in risk of adult leukemia was found for all transmitters combined (p=0.05), two of the transmitter groups, and three of the single transmitters ; for all transmitters combined, observed excess risk was no more than 15% at any distance up to 10 km, and there was no observed excess within 2 km of transmitters (O/E ratio=0.97,95% CI 0.78-1.21).
