At 11:46 on Sept. 3, MEP (NNSA) activated the Level II emergency response to the sixth nuclear test of DPRK on 11:30 that day, and worked with MIIT, MWR, NHFPC, CEA, CMA, SASTIND, the army, and the armed forces to coordinate Heilongjiang, Jilin, Liaoning, and Shandong to launch emergency monitoring of the radiation levels in the northeast border and surrounding areas, sample and analyze the artificial radionuclides, and provide technical estimations, with the support of emergency rescue teams from Beijing, Anhui, Inner Mongolia, and Sichuan. The monitoring data indicated zero abnormality during the eight days’ consecutive monitoring. Based on the overall assessment with relevant departments, MEP (NNSA) held that the DPRK nuclear test does not have any negative impact on the environment in China and meets the conditions to be ended, and therefore decided to terminate the emergency state at 18:00 on Sept. 10.
By 18:00 on Sept. 10, 7,768 sets of data had been acquired through the real-time consecutive monitoring at automatic monitoring stations in the northeast border and surrounding areas, the mobile monitoring via mobile monitoring vehicles, the aerial monitoring, and the field sampling and monitoring. The data indicated the radiation levels within normal range. Specifically, the automatic monitoring stations in Heilongjiang, Jilin, Liaoning, and Shandong obtained 6,681 sets of data, collected 522 aerosol samples, 205 gas iodine samples, 152 surface water, groundwater, and drinking water samples, 33 rainwater samples, 66 sediment samples, 8 drone swipe samples, and 101 mobile monitoring data, none indicative of abnormality.
The CPC Central Committee and the State Council have attached great importance to the emergency response to the DPRK nuclear test. The State departments, member organizations of the emergency team, and the local governments at all levels have collaborated actively. The army and the local areas have shared information and worked together to set up a parameter to guard the nuclear and radiation safety at the border of China and North Korea, and made sure the emergency response to be successful.
Upon the ending of the emergency response state, the monitoring of radiation levels will return to the routine monitoring. MEP (NNSA) will continue with the automatic monitoring, early warning monitoring, and regular sampling, analysis, and monitoring of radiation environment in the key areas of the border. The automatic monitoring stations in the northeast border and surrounding areas will continue to release the real-time, consecutive air dose rate, provide public access to the data, and respond to the public concerns in a timely approach.
