This paper presents calculated specific absorption rate (SAR) dosimetry in 4 and 8 week Japanese pregnant-woman models exposed to plane waves over the frequency range of 10 MHz-1.5 GHz. Two types of 2 mm spatial-resolution pregnant-woman models comprised a woman model, which is similar to the average-sized Japanese adult female in height and weight, with a cubic (4 week) embryo or spheroidal (8 week) one. The averaged SAR in the embryos exposed to vertically and horizontally polarized plane waves at four kinds of propagation directions are calculated from 10 MHz to 1.5 GHz. The results indicate that the maximum average SAR in the embryos exposed to plane waves is lower than 0.08 W kg(-1) when the incident power density is at the reference level of ICNIRP guideline for general public environment.
本文给出了在频率范围为 10 MHz-1.5 GHz 下,对暴露于平面波的 4 周和 8 周日本孕妇模型进行计算的比吸收率(SAR)剂量测定。两种具有 2 毫米空间分辨率的孕妇模型包括一个与平均身高和体重的日本成年女性相似的女性模型,以及一个立方(4 周)胚胎或球形(8 周)胚胎。从 10 MHz 到 1.5 GHz,计算了在四种传播方向下垂直极化和水平极化平面波照射下胚胎的平均 SAR。结果表明,当入射功率密度处于 ICNIRP 一般公众环境导则的参考水平时,胚胎暴露于平面波的最大平均 SAR 低于 0.08 W/kg。
