In the three and a half centuries after the worst nuclear accident in history, the Chernobyl disaster was in symbolic memory and The actual impact that can still be felt in an area -Northern Ukraine, very close to the border with Belarus-Last year, arson occurred in the forests of the region, causing radiation peaks that were 16 times higher than normal.
An obvious example of this dual aspect is the commemorative flight of the remains of a nuclear power plant organized by the Ukrainian national airline UIA last Sunday. The price is about 90 eurosPassengers observed the tragic scene from the “most unusual angle”, but always abide by safety standards: the equipment must never fall below 900 meters, which is the minimum allowed.
Pripyatat, the residential town closest to the power station at the time of the disaster, is now particularly in distress: a ghost town for humans; it may be a nature reserve for animals. In fact, after several years of hard work, the Ukrainian government has restarted its initiative to request UNESCO to declare the areas immediately affected by the disaster. So-called restricted zone The radius of 30 kilometers from the plant remains, including the city itself, is also listed as a World Heritage Site. Although scientific research has determined that the disappearance of radiation in certain areas (if any) will take 24,000 years to achieve.
Therefore, Prípiat (Prípiat) specific spectral landscape photo report is full Ruins consumed by weeds They seem to have appeared at the same time new research on the effects of radiation on the descendants of tragedy survivors and crops in the area-milder than the first case, worse than the first case. –
Finally, the public debate is also moving between these two trends: The ghost of the former Soviet UnionThe previous leaders of the review reviewed the terrible management of the disaster and its impact on the Red Giant’s dissolution process as well as the current nuclear security reality, which was driven by another recent nuclear disaster, such as the one in Fukushima in 2011 Japanese power plant.
“Thirty-five years later, we are still trying to understand the full impact of Chernobyl on the world. However, in reality, we live in a world defined by Chernobyl. The researchers explained: “This is terrible : A nuclear accident is a nuclear accident no matter where it is. ” Mariana budjeryn Bulletin of Atomic Scientists to assess their tragedy.
The event started 1:23 am on April 26, 1986, During the planned testing of the safety system in Unit 4 of the factory. The power outage, coupled with a series of operator errors, caused the device’s RBMK reactor core to melt and be affected by graphite.
Because the reactor was not protected by the containment, the steam explosion produced Break through the roof of the unit There are large pieces of fuel rods and highly radioactive graphite everywhere. The resulting fire produced radioactive smoke, which carried contaminated particles throughout Ukraine, Belarus and Russia, as well as Scandinavia and Europe.
According to the official death toll recognized by the international community, 31 deaths The explosion is a direct consequence, and the United Nations estimates that only 50 deaths can be directly attributed to this disaster. However, he predicts that in 2005, at least 4,000 people will die from radiation exposure, many of whom are residents of Prípiat, whose 50,000 residents will be evacuated and never return.
The true number of people affected is unknown. Viktor SushkoThe deputy director of the National Center for Radiological Medicine Research (NRCRM) in Kiev, Ukraine, said that Chernobyl estimated that the British BBC channel was “the largest man-made disaster in human history.” The Soviet Union, including 10,000 people, was hit hard.
Chernobyl continued to generate electricity for 14 years, until international pressure forced it to shut down in 2000. Nowadays, Unit 4 is covered by a raised dome With the help of the international community, the Ukrainian government established a nuclear fuel depot.
Last Thursday, a study published in the journal Science showed that the results of the descendants of the Chernobyl disaster and the descendants of Fukushima were relatively reassuring.There is no evidence that parents exposed to radiation can spread Any unnecessary mutations According to research, this is one of the most important events in the history of the region.
“National Geographic” said: “Although the document can not completely rule out this possible impact, but this study clearly shows that this risk is much lower than current expectations.” Robert Ullrich, Vice Chairman of the Radiation Effects Research Foundation.
Another study by the team investigated the relationship between the Chernobyl rainstorm and hundreds of thyroid cancer cases in exposed people.In this regard, the researchers also found that cancer caused by radiation does not have any “Biomarkers” Unique and unique.
The impact on the ground is more serious. end of last year, University of Exeter with Ukrainian Institute of Agricultural Radiology The conclusion is that crops in the vicinity of Chernobyl still show signs of contamination.
