March 28, environmental protection department (State Bureau of Nuclear Safety) The relevant persons in charge introduce, after the department in environment protecting mode continues for the 26, 27th of March and measures to extremely micro- manpower radioactive nuclide iodine - 131 in the aerosol sample of the monitoring point of Heilongjiang Province Northeast, in our country coastal Jiangsu Province in southeast on the 28th, Shanghai, measure in the monitoring point aerosol samples of Zhejiang Province, Anhui Province, Guangdong Province, some areas of the Guangxi Zhuang Autonomous Region to extremely micro- manpower radioactive nuclide iodine - 131, its density is in quantity of 10-4 Beckler / cubic meter grade and following. Combine the environmental monitoring data analysis of local radiation in recent years, confirm tentatively iodine measured - 131 comes from the nuclear accident of Fukushima of Japan. Extremely faint because of the additional radiation dosage brought of radioactive nuclide of manpower that is detected, smaller than 1/100,000 of the radiation dosage of this natural bottom, still within the horizontal fluctuations range of radiation of this bottom of the locality, so does not need to adopt action of any shelter. The aerosol in other areas of the whole country of department in environment protecting mode takes a sample the monitoring point has not confirmed measuring the radioactive nuclide of manpower from nuclear accident of Fukushima of Japan yet at present. To iodine - content 131 in the air which Jiangsu monitors, the radiation environmental monitoring head of administrative station Lu Ji in Jiangsu Province expresses root, this is very micro-, does not have any influence on the environment, the concrete relevant data will be announced on the websites of drawing room in environment protecting mode of the province today. Jiangsu food and drinking water have not detected radioactive pollution yesterday temporarily, the department of public health of Jiangsu Province released news, it shows to monitor the result, by March 28, have not detected the radioactive pollution in Jiangsu food and drinking water. After the nuclear leakage accident happened in Japan, the department of public health of the province has been paying close attention to the development of the state of affair, and according to factors such as the radioactive material release speed, meteorological condition,etc., from March 12, in the intersection of Nanjing and city and coastal Nantong, Yancheng, the intersection of Lianyun Harbour and 3 city and 10 counties had jurisdiction over ' Municipal or district) Monitor the radioactive level of pollution to leaf vegetables,etc. food and drinking water, the expert says, has not detected the radioactive pollution at present. The relevant person of department of public health of province introduces, is measured from Japanese entry personnel and find that receive the radioactive pollution if entering a country, can reach province Center for Disease Prevention and Control that the department of public health of the province appointed, Suzhou university attaches to 3 medical health organs such as the second hospital, first hospital of Lianyun Harbour and deals with and damages and treats and cures with radiation personnel's radioactive pollution detection, medical science. Nanjing port is measured and has not found temporarily the radioactive material goes beyond and marks for March 24, State Bureau of Quality Testing releases the announcement, it is forbidden some Japanese food agricultural products are imported. As to this, the inspection and quarantine of Nanjing office pays close attention to, establishes inspection and quarantine to supervise leading group and work group, strengthen and measure, prevent being imported by the food agricultural products of radioactive pollution, and set up reporting system, implement the special messenger to check, the special messenger sends nuclear radiation and measures the situation, make sure information is accurate, there is not implementing a report too of situation. It is reported, there is fewer inward quantity of agricultural product of Japanese food of port from Nanjing at present, use food for special meal mainly ' Such as receiving kinase of beans) ,Have not found temporarily that there is phenomenon that radioactive material density exceeds standard. How is the radiation environment of Jiangsu? What is the level of this bottom of natural radiation of Jiangsu? The expert tells reporters, the nuclear radiation source in the life of our country is mainly a natural radiant. During 1983~1990, the national department in environment protecting mode launched the horizontal investigation of natural radioactivity of the environment in the whole country. The reporter sees in the national province ' District) , in the municipality directly under the Central Government, the intersection of radiation and environment of Jiangsu rank very low, annual effective dose of per person whether 0.48 fine long hair wish dog days. This number value is only a bit higher than Beijing and Shanxi, it is lower than the other provinces. The radiation environmental monitoring head of administrative station Lu Ji in Jiangsu Province root recommend, natural radiation shines and lets this bottom shine too, mainly come from internal natural radiosiotope potassium - 40 that exists of human body; Radiosiotope and cosmic ray existing in the rock, soil and water body, generally speaking the higher the terrain is, it is the more strongly to shine by the cosmic ray. After Jiangsu monitors the range to expand for 17 days going through Japan's nuclear leakage accident to the soil drinking water marine product, yesterday, the bulletin reporter visited the drawing room in environment protecting mode of Jiangsu Province located in Scien-tech garden of new city of the west of river of Nanjing and radiated the environmental monitoring station again. It is introduced, besides monitoring of nuclear factor of radioactivity in the regular air, since March 25, the radioactive monitoring range of Jiangsu is expanded to soil, drinking water, surface water, living beings, marine product and sea water. Meanwhile, the rainwater in Nanjing was collected as soon as possible and sent to the laboratory and analyzed too last week. Report a datum every 3 hours On the second day after 9.0 magnitude of enormous earthquake of the Northeast of Japan, Jiangsu monitored the air radiation of the whole province. Require since March 25, Jiangsu subside dust, precipitation to Nanjing, the intersection of Lianyun Harbour and two city according to the intersection of country and environmental protection portion, the soil, living beings, surface water, drinking water, sea water, marine product of two cities in Nantong, Lianyun Harbour monitor. In order to judge most fast whether the environment receives the influence of radiation, at present, Jiangsu Province rises to 9 from 7 automatic nuclear radiation monitoring stations, and arrange 11 and monitor the position manually, and large and abundant in Yancheng have set up a portable automatical monitor station. Gather and stand and control the iodine content of aerosol in the air closely automatically, gather a datum every 3 hours, guarantee the systems of eight newspapers for one day. It is for Nantong, Lianyun Harbour two coastal cities that water and biological radiation are monitored. The sample gathered at present is as follows, sea water, sea salt, sea of Lianyun Harbour living beings, land biological ' Including vegetables) ; Soil, surface water, drinking water, sea water in Nantong. Meanwhile, the drawing room in environment protecting mode of Jiangsu Province pollutes the situation in order to grasp surface of Japan's entry plane in an all-round way, successively set out the corrupt monitoring that 24 persons glued the surface to the planes of 12 of Nanjing, Wuxi, have already come from the radioactive material activity that Japan's nuclear leakage releases and paid and monitored to 24 samples. The sampling machine of ultra high flux caught the radiation factor by yesterday, the whole province of Jiangsu had already laid 17 atmospheric sampled points, mainly distributed in the coastal area, sample the device through high flux, carry on dust such as the aerosol in the air all-roundly and sample. The radiation environmental monitoring head of administrative station Lu Ji in Jiangsu Province root recommend, after the nuclear leakage took place in Japan, the ones that started were monitored by air at first, because the air can catch to and radiate the factor to sample first fastest. The pollution that and water and organism receive radiation is a progressive course of subsiding. The reporter knows, has also disposed the aerosol of first ultra high flux in Jiangsu to sample the device in Nanjing automatically, only this one, 24 The sample volume gathered hour is about 1500 cubic meters, it is to sample 10 times of the device to sample the speed ordinarily. "Have the new joining of machine, buoyant the intersection of radiation and factor those can be caught to within short time in the air, even the extremely faint radioactive factor in the air. " The reporter sees in the rooftop of the environmental monitoring station of Jiangsu radiation, it is a meteorograph to reveal six parameters above a million instruments of this value, including wind direction, wind speed, atmospheric pressure, rainfall, temperature, humidity, " air aerosol sample that they are gathered, enter the intersection of province and radiation, stand behind the laboratory, through the intersection of garmma(��) and the intersection of energy spectrum and appearance, can go on the whole factor determining the nature, quantitative analysis to the radioactive nuclide in the the samples. " The monitoring data of the sea water of ocean fishes want etc. There are the coastal sea water, seafood and vegetables in Jiangsu on earth " Infected with " Have and radiate the factor? Staff member of monitoring station introduce the radiation of Jiangsu, except gather it with back-end detection, analysis while measuring, there is a complicated sample preconditioning course in the middle. The distance from Jiangsu of Japan is farther, from the viewpoint of experiment, the grade of unit of the radiation content is in " 1/100,000 " ,This needs a large amount of concentration. Such as the sea water, experiment personnel should gather 100 liters once. And dozens of kilograms of ocean fishes samples should air-dry the fish first, reject the fish, carry on carbonization, also want through high temperature dust their later, sample have only 200~300 grams after the dust, can carry on lab analysis at this moment. Such preconditioning course is very time consuming, so, measuring entirely should be for longer time. "It generally takes about one week for the water sample to monitor, and the marine product can publish the result until month most quickly. " The intersection of Japanese and spinach that report not long ago, and the intersection of radiation and quantity in the milk measure what can produce result fast? The expert explains, after the nuclear pollution accident, the radioactive material in the drinking water, food of Japan exceeds standard too much, the sample of small quantity, simple preconditioning can make it reach survey lower limit of the instrument. This it is one emergency that measure, speed nearly getting many. Lu Ji root say the intersection of monitoring and result of Jiangsu indicate the whole province radiation environment in normal competence temporarily so far, the drinking water has not been influenced temporarily, the surrounding environment radiation level of nuclear power station of gulf of field of Jiangsu is in the normal range temporarily too, in safe operation state, ask the public to rest assured. After the rainwater of Nanjing is carrying on radiation and analyzing Japan's nuclear crisis, Tokyo, Massachusetts state of U.S.A. all monitor out " The radiation rain " ,A lot of whom citizen of Nanjing afraid under the last week even was there radiation in the rain? Meanwhile, begin from the last week rainfall the first quarter, " sampling device of acid rain " of the rooftop of monitoring station Begin to concentrate on collecting rainwater samples, send to radiation and stand in the laboratory and monitor incessantly, "it is estimated the result comes out to this weekend. " The shift engineer says: "Since so far, it has had influence of nuclear radiation that the atmosphere is sampled and monitored and has not gathered to yet, that is to say tiny particle in the air, monitor, produce, influence by nuclear radiation yet so far, the whole air circulates the precipitation recently, the report not polluted yet either at present in the convection. " The reporter sees, this set of acid rain sampling device can be " done wetly and dual-purposely " too ,If it rains and can open the cover automatically " Collect water " ; When it is fine, such acid rain inductor can be turned the jar into the body " to subside " Precipitate, absorb the particle in the air automatically.
