On April 5, the source of radioactive contamination was discovered in the city of Kravchuk in Khabarovsk, Russia. The Heilongjiang Provincial Department of Ecology and Environment has paid close attention, and in the past few days, the Heilongjiang Provincial Atmospheric Radiation Environment Automatic Monitoring Station has monitored the radiation dose rate of γ and collected aerosol samples in real time 24 hours a day, and the monitoring results are at a normal level and there is no abnormality.

Radiation monitoring at the border showed that the Khabarovsk radioactive source had no impact on Heilongjiang Province
On April 5, the source of radioactive contamination was discovered in the Russian city of Khabarovsk, and a state of emergency was imposed locally. In the past few days, the Heilongjiang Provincial Atmospheric Radiation Environment Automatic Monitoring Station has monitored the radiation dose rate of γ and collected aerosol samples in real time 24 hours a day, and the monitoring results are at a normal level and there is no abnormality.

There are a total of 27 automatic monitoring stations for the atmospheric radiation environment in Heilongjiang Province, among which two automatic monitoring stations in Fuyuan and Tongjiang areas of Jiamusi City are the closest to the Khabarovsk region, about 60 kilometers and 210 kilometers, which can monitor the radiation dose rate of γ and collect aerosol samples in real time 24 hours a day. Since April 5, the results of continuous automatic monitoring have shown that the radiation level is at a normal level and there are no abnormalities.
On April 8, Russia's TASS news agency reported that the radiation background at the site of the Khabarovsk industrial zone, which had previously been in emergency mode, had returned to normal. On April 9, the mayor of Kravchuk, Khabarovsk, Russia, signed an order announcing the lifting of the state of emergency imposed in the city from April 10 due to the discovery of a radioactive source of contamination (a cesium-137 capsule on an industrial flaw detector, which has now been transferred to a professional regulatory body). This incident did not adversely affect the health of residents and the surrounding environment. At present, production and life in Khabarovsk are in normal order.
According to experts from the Heilongjiang Provincial Institute of Atomic Energy, if it is determined that the radiation source found is a "radioactive source", the stainless steel outer shell of the radioactive source is not damaged, the contents are not scattered or lost, and it is not other nuclear materials and other nuclear materials, and the Russian side has safely placed the radioactive source in a container and sent it to a radioactive waste temporary storage facility for storage, the radiation value at the place where the incident occurred will be reduced to a normal level, and will not continue to have a radioactive impact on the local area, nor will it cause harm to the human body.
