Does Japanese radiation have a big impact on Qingdao tourism now?

People's Daily Online, Qingdao, March 23 (Reporter Yang Hong) Today, we learned from a press conference held by the Qingdao Municipal Government that the quality of the atmospheric radiation environment in Qingdao is normal, and the radioactivity in coastal seawater and sea surface air is at a level of The background level is currently not affected by the Japanese nuclear accident.

According to the relevant person in charge of the Qingdao Municipal Environmental Protection Bureau, after the nuclear accident caused by the "Japanese earthquake" on March 11, the Bureau received an emergency order from the Ministry of Environmental Protection on March 12 and immediately launched " In response to the "Japan Earthquake" special radiation environment emergency monitoring work, two automatic radiation environment stations in Qingdao are used to continuously monitor the radiation environment conditions for 24 hours. The automatic detection system detects once every five minutes. By detecting the intensity of radioactivity in the air, Qingdao City's Nuclear contamination situation.

In view of the main radioactive materials leaked from nuclear power plants, starting from March 13, the Bureau increased the focus of measurements of iodine-131, cesium-137 and other nuclides in the air. Monitoring items include iodine-131 in the air, cesium-137, zirconium-95, ruthenium-103, ruthenium-106 and other nuclear fission-focused nuclides in aerosols. Samples are analyzed and tested once a day.

Since March 16, Qingdao City has selected four points in the offshore waters facing Japan to conduct analysis of radionuclides in seawater.

As of March 22, the hourly mean range of γ air absorption dose rate at the Qingdao Radiation Automatic Station is 83.5-91.2 nanosifters per hour. According to monitoring data statistics in recent years, Qingdao’s normal radiation The background range is between 70.5 and 159.4 NSF per hour. The monitoring results show that the quality of the atmospheric radiation environment in Qingdao is normal and has not been affected by the Japanese nuclear accident. The test results are within the normal range.

The iodine-131 and aerosol samples in the air and seawater samples collected so far have been analyzed by instruments and no nuclear fission-related nuclides have been detected. The results show that the seawater quality near Qingdao City is not currently contaminated by radioactivity. .

The radiation monitoring data of cities adjacent to Qingdao announced by the Ministry of Environmental Protection are consistent with the test results of Qingdao. None of them were affected by the Japanese nuclear accident. The Qingdao Municipal Environmental Protection Bureau has set up a "Qingdao Radiation Environment Monitoring" column on the homepage of the bureau's website. It releases the city's radiation environment monitoring data twice a day, and citizens can log in to check it.

According to the relevant person in charge of the North Sea Branch of the State Oceanic Administration, technicians from the North Sea Monitoring Center boarded the China Maritime Surveillance 23 ship on the night of March 12, and the China Maritime Surveillance 15 ship began to carry out seawater radioactivity and sea surface monitoring in the central and northern Yellow Sea. Atmospheric monitoring.

As of 12:00 on March 22, 2011, there were 8 seawater monitoring stations and 271 sea surface and atmospheric monitoring stations in the Yellow Sea, and 1 seawater and 12 sea surface and atmospheric stations were monitored in Qingdao offshore waters. The farthest monitoring station is 292 kilometers from the mainland and 394 kilometers from Qingdao. Radioactivity monitoring results show that radioactivity in Qingdao's coastal seawater and sea surface atmosphere is at background levels.

The radioactive monitoring results show that no abnormalities were found in the sea water and sea surface atmosphere in the monitored sea area, and neither was affected by the Fukushima nuclear power plant accident in Japan.

The North Sea Forecast Center of the State Oceanic Administration analyzed the impact of radioactive pollutants from the nuclear leakage of Japan's Fukushima Daiichi Nuclear Power Plant on the ocean and atmosphere in the eastern sea of ??my country. The prediction is as follows: In the next 72 hours, the impact of radioactive pollutants in the sea east of Japan will be The flow flows in the northeast direction, with mainly westerly winds at high altitudes and southerly to westerly winds at low altitudes. Based on the above ocean and atmospheric dynamic conditions, the main impact area of ??radioactive materials generated by the accident is eastern Japan and the northwest Pacific region to the east. , does not have the dynamic conditions to affect the eastern sea areas of my country.

This is the latest reported news. Hope it helps you. You can refer to it more. . If you feel satisfied with my answer. Please accept it as the standard answer. . Thanks.
