基本解释

The amplitude of the electromagnetic field (radiation) is one fourth the strength at a distance of two inches and fifty times lower at three feet.
手机对人体的辐射强度，在两英寸的距离时，减少到四分之一，在三英尺的距离时，会降低到五十分之一！
The experiment of lighting radiation effect on rocket is done by using LSG-8015 lighting surge generator which establishes lightning electromagnetic pulse radiation field.
利用LSG-8015型雷电浪涌发生器与平行板传输线配合模拟雷电电磁脉冲辐射场，对整装状态下水平放置的某型火箭弹进行了辐照试验。
The researchers presumed that electromagnetic field radiation from cell phone may result in high blood pressure though they have not explained the phenomenon properly by now.
尽管时下尚不清楚使用手机究竟是如何导致血压升高的，但是研究人员推测，可能是手机发出的电磁场不知何故使得血压升高。
