Children's brains are more susceptible to hazardous exposures, and are thought to absorb higher doses of radiation from cell phones in some regions of the brain. Globally the numbers and applications of wireless devices are increasing rapidly, but since 1997 safety testing has relied on a large, homogenous, adult male head phantom to simulate exposures; the “Standard Anthropomorphic Mannequin” (SAM) is used to estimate only whether tissue temperature will be increased by more than 1 Celsius degree in the periphery. The present work employs anatomically based modeling currently used to set standards for surgical and medical devices, that incorporates heterogeneous characteristics of age and anatomy. Modeling of a cell phone held to the ear, or of virtual reality devices in front of the eyes, reveals that young eyes and brains absorb substantially higher local radiation doses than adults’. Age-specific simulations indicate the need to apply refined methods for regulatory compliance testing; and for public education regarding manufacturers' advice to keep phones off the body, and prudent use to limit exposures, particularly to protect the young.

儿童的大脑更容易受到危险的暴露，并被认为会吸收大脑某些区域中手机产生的更高剂量的辐射。在全球范围内，无线设备的数量和应用都在迅速增长，但是自1997年以来，安全测试一直依靠大型，同质的成年男性头部幻像来模拟暴露情况。“标准拟人模型”（SAM）仅用于估计组织温度在周围是否会升高超过1摄氏度。本工作采用基于解剖学的模型，该模型目前用于设置手术和医疗设备的标准，该模型结合了年龄和解剖学的异质性特征。对耳朵上的手机或眼前的虚拟现实设备的建模，揭示年轻的眼睛和大脑比成人吸收的本地辐射剂量要高得多。特定年龄的模拟表明需要使用改进的方法进行法规遵从性测试；以及针对制造商的建议进行公众教育，使他们远离手机，并谨慎使用以限制暴露，尤其是保护年轻人。
