Abstract

SAR calculation method following the Mobi-Kids study protocol is analyzed and evaluation method of cumulative RF dose from mobile phones which have been used by a subject of case and control groups is proposed. An SAR database is built by calculating SAR distributions in 4 head models at different ages for representative phone models with the same conducted power. To obtain SAR distribution in a subject's head for a specific commercial phone which had/have been used by him/her, an SAR correction factor using SAR compliance test results is determined. Cumulative dose is calculated by considering mobile phone characteristics and use pattern such as call time and laterality(right and left).

본 논문은 Mobi-Kids 연구의 노출량 평가를 위해 휴대전화 대표 모델에 대해 연구 프로토콜에 따른 SAR 계산방법을 분석하고, 역학조사 대상자가 사용한 휴대전화의 무선주파수 누적 노출량을 평가하는 방법을 제안한다. 휴대전화 대표 모델의 출력을 동일하게 가정하고, 서로 다른 연령의 4개 머리 모델에서의 SAR 분포를 계산하여 데이터베이스를 구축한다. 역학조사 대상자가 사용한 특정 휴대전화 모델의 머리 SAR은 SAR 적합성 시험결과를 활용하여 보정 인자를 적용함으로써 구한다. 그리고 휴대전화 특성과 함께 사용 시간, 좌 우측 비율 같은 대상자의 휴대전화 사용 패턴에 대한 인자를 고려하여 누적 에너지를 산출하게 된다.
