China says no radiation harm from North Korea nuclear test

This undated picture released by North Korea's official Korean Central News Agency (KCNA) on September 3, 2017 shows North Korean leader Kim Jong-Un (C) looking at a metal casing with two bulges at an undisclosed location. 

North Korea has developed a hydrogen bomb which can be loaded into the country's new intercontinental ballistic missile, the official Korean Central News Agency claimed on September 3. Questions remain over whether nuclear-armed Pyongyang has successfully miniaturised its weapons, and whether it has a working H-bomb, but KCNA said that leader Kim Jong-Un had inspected such a device at the Nuclear Weapons Institute. / AFP PHOTO / KCNA VIA KNS / STR / South Korea OUT / REPUBLIC OF KOREA OUT ---EDITORS NOTE--- RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT "AFP PHOTO/KCNA VIA KNS" - NO MARKETING NO ADVERTISING CAMPAIGNS - DISTRIBUTED AS A SERVICE TO CLIENTS THIS PICTURE WAS MADE AVAILABLE BY A THIRD PARTY.

China has concluded that radiation levels remain normal in the provinces near the North Korean border after Pyongyang’s most powerful nuclear test yet spurred concerns of residual environmental damage.

The Ministry of Environmental Protection announced Sunday it was ending its emergency radiation monitoring in response to the blast last week, which the North claimed was the successful detonation of a hydrogen bomb.
“A comprehensive assessment has concluded that this DPRK nuclear test has caused no environmental impact on China,” the ministry said in a statement posted on its website, using the initials of the North’s official name.
“After eight days of continuous monitoring, no abnormal results were shown.”
More than 1,000 aerosol, air, iodine, water and sediment samples were taken at monitoring stations in northeast Heilongjiang, Jilin and Liaoning provinces as well as in eastern Shandong province, according to the ministry.
The explosion from the most recent nuclear test, the North’s sixth, was considerably larger than previous tests and was felt by residents in Chinese cities hundreds of kilometres from the border.
Japan also said last Monday that it had not detected any atmospheric radiation in monitoring posts across the country
