Kiev - 1986 (Part-1)
During the explosion of the 4th unit of the Chernobyl nuclear power plant, on April 26, 1986 at 01:24, there was a release of radioactive substances into the atmosphere. The radionuclides first entered the atmosphere, and already dropped out of it on the territory. In the reports and descriptions of the dosimetrists who traveled around the exclusion zone, maps of pollution were compiled, it was argued that the territory is of a local nature of infection. Based on this, three areas were identified that were most susceptible to radiation pollution: the western trace; northern trail; southern trail. Chernobyl cesium and strontium was discovered in Europe and America, but what can we say about the capital of Ukraine!
From Kiev to the Chernobyl station - 110 kilometers in a straight line. At 11 a.m. on April 30, at one of the weather stations in Kiev, a radiation background of 2200 micro-roentgen per hour was recorded. But, the capital was lucky in terms of infection, because there was a strong wind stream, and most of the radionuclides simply did not have time to fall into the territory, it was carried a long distance to the Black Sea. But, nevertheless, from April 30 to May 3, the background radiation in different areas of Kiev was from 800 micro-roentgen to almost 3,000 micro-roentgen (a hundred times higher than the sanitary permissible norm). In some apartments, a background radiation of up to 100 microroentgen per hour was observed. Background, during May-June, from 500 to 1100 microroentgen per hour was kept in Kiev, this information is from declassified KGB reports.
Subsequently, the explosion of the 4th block of the Chernobyl nuclear power plant, particles of nuclear fuel, fell into the Pripyat River and migrated to the Dnieper during the course. Specialists of the Institute of Colloid Chemistry and Water took water samples in the Dnieper River for research. The results were shocking - a thousandfold excess of beta particles. Experiencing the rest of the water bodies, measurements were taken at the Kanevsky, Kremenchug and Kakhovskoye reservoirs. According to the results of the studies, no changes in water quality standards established by the USSR Ministry of Health were found. A round-the-clock headquarters was created, which monitored the quality of water in all reservoirs of Kiev, Zhytomyr, Chernihiv, Cherkasy and other areas.
But the Kiev reservoir had to wish for the best. 9 months after the disaster, an excess of radiation standards in tap water was detected. In this regard, a number of measures have been developed in Kiev to prepare all artesian wells, an additional 58 have been drilled in case the situation with water becomes worse. And to this day it is not known how many radionuclides remain in the organisms of Kiev.
