| Model | Radiobroadcast and TV tower exposure (residential proximity) and correlations with leukemia in children | |
| Details | Children with leukemia (n=1959 diagnosed Jan 1 1984 to Dec 31, 2003, n=5848 controls) were examined for correlations with residential proximity to 16 AM transmitters (> 200 kW), 8 FM/TV transmitters (> 200 kW FM or > 500 kW TV)radio or television transmitters. An initial feasibility study addressed methods for exposure assessment, definition of a suitable study region, consideration of important confounders (other relevant correlated risk factors), and assessment of the statistical power needed for the study. The authors performed 477 RF measurements and used these mappings in addition to simple distance to the transmitter. High exposure (90% quantile) was defined as 0.504-7.742 V/m (total RF). The authors report no correlation between all types of leukemia and increased field levels (OR=0.86; % CI = 0.67-1.11). A non-significant increase for all childhood leukemia types was reported with distance - 2 km vs 10-15 km from nearest AM transmitter (OR = 1.31; 95% CI 0.80-2.15), although this was based on 14 cases. A paper characterizing the exposure assessment confirmed that information obtained from the operators of radio towers as well as that collected in the main study was validated by additional field measurements and calculations. In a subsequent combined analysis of lymphocytic leukemia results from Korea (Ha et al 2007) and Germany (Merzenich et al 2008), the authors found no association with total RF exposure although the ORs for living within 2 km of broadcasting towers were similar in both studies. |
