Description
The CIRE-RF project (Childhood cancer in relation to RF-EMF from television and radio broadcast stations) aims to investigate potential risks of childhood cancer in relation to RF-EMF from TV and AM/FM radio broadcast stations. The CIRE-RF study is based on a GEOCAP-Diag case-control study which includes 20,344 cases and 60,189 controls recruited between 2002 and 2013 in France. In this abstract we analyse prevalence of exposures to RF-EMF from AM antennas in metropolitan France in the period 2002-2013, among children who did not have cancer at the time of recruitment.
We identified AM broadcast towers in the vicinity or with substantial impact on exposure levels of each control previously recruited in GEOCAP study. For each study subject, we calculated annual local outdoor average field strength (V/m) at the geocoded addresses of the residence separately for long-wave (LW) and medium-wave (MW) broadcasting frequencies as exposure metrics. The lowest estimated average annual field strength for AM-LF was 0.02 V/m. Fifty percent of the study population was exposed up to 0.09 V/m, 95% up to 0.24 V/m with maximal value reaching 8.99 V/m. For AM-MW transmitters, the lowest estimated average annual field strength for the period 2002-2013 was 0.03 V/m. Fifty percent of the study population was exposed up to 0.12 V/m, 95% up to 0.51 V/m with maximal value reaching 21.14 V/m.
Further analyses will include description of FM and analogue TV sources, followed by the cancer risk assessment.
