The Ministry of Environmental Protection has begun emergency radiation monitoring following the nuclear test conducted by the Democratic People's Republic of Korea (DPRK), saying that the test hadn't affected China's environment so far.
The DPRK announced Wednesday that it had tested a hydrogen bomb. It resulted in a 4.9-magnitude earthquake with an epicenter less than 100 km from the country's nearest border with China.
As of 1 p.m. Wednesday, readings from 25 monitoring stations in the border areas were between 65 and 95 nGy/h, which is within the normal range.
The ministry said it will conduct both automatic reading and human sampling and analysis and report the readings "in a timely manner."
