毫希

Langhorst说，辐射疾病（或急性辐射综合征）通常发生于全身辐射水平超过3000毫希以上，为每年公众允许辐射上限的3000倍。

Radiation sickness ( or acute radiation syndrome ) usually sets in after a whole-body dose of three sieverts & 3,000 times the recommended public dose limit per year , Langhorst says .

测量核辐射的一种方式是为毫希为单位来测量。

One way of measuring nuclear radiation is in units called millisieverts .

美国规定辐射工作人员的辐射上限为每年50毫希，但很少有工人接受的辐射水平接近这个数值。

The U.S.limit for radiation workers is50 millisieverts annually , although few workers are exposed to anything approaching that amount .

这个星期在东京，牛津大学的物理教授韦德-埃里森说，基于目前的健康统计，日本的剂量限制可以安全的提高到100毫希。

This week in Tokyo , Wade Allison , a physics professor at Oxford University , argued that Japan 's dose limit could safely be raised to100 millisieverts , based on current health statistics .
