この研究は、イラクの都市バアクーバで、2010年の5-6月に、8ヵ所の携帯電話基地局周辺に１年以上居住する人を無作為抽出し（n=375：女性200人、男性175人）、非特異的健康症状（NSHS）を調査した横断研究である。対象者を基地局からの距離300m以内とそれより遠方に分けた分析では、距離300m以内の居住者の方が、遠方の居住者に比べ、さまざまな不定愁訴の報告が多かった、などを報告した他、距離区分を10、50、100、200mとした分析の結果も報告している。

結論(著者による)

Most of the health complaints such as headache, irritability, nausea, appetite loss, discomfort, sleep disturbance, depressive tendencies, memory loss, difficulty in concentration, dizziness and lowering of libido were statistically significantly more often reported by residents living in a distance of less than 300 m to a base station compared to those living in a distance of more than 300 m to a base station. Significant differences were observed up to 100 m to a base station for symptoms such as: headaches sleep disturbances, irritability, depressive tendencies, feeling of discomfort, difficulties in concentration, memory loss and lowering of libido.
The authors suggested that mobile phone base stations should not be sited closer than 300 m to residences to minimize exposure of the residents.
