They found spots where radiation levels exceeded 100 microsieverts per hour, about the same dose as a chest X-ray.

Reportedly, levels of radiation have temporarily exceeded 1,000 micro sievert, which is twice the legal upper limit;

据报道，核辐射标准临时性的超过了1000单位的微西弗，这已经是法定标准限制的两倍了；

Reportedly, levels of radiation have temporarily exceeded 1,000 micro sievert, which is twice the legal upper limit; but in many cases they have been little worse than an X-ray.

据报道，辐射量一度超过一千微西弗（micro sievert），这是额定上限的两倍；但在一般情况下，这并未超过一次X光检测的剂量。

Radiation levels in Miyagi are around POINT ZERO FIVE micro-sievert, half that of Tokyo.

On Thursday night, it said the radiation level there was 3, 600 microsieverts per hour, only slightly lower from those seen in the morning.
