Nuclear power is dangerous and their use is fraught with uncertainties, as the interventions made on Thursday at an international conference to mark the 25 anniversary of Chernobyl. However, none of the speakers at the plenary of the event, held in Kiev, questioned the future of nuclear energy, despite the serious consequences of the accident at that nuclear plant, the worst in the history of civil atom.
Overcome these consequences take centuries. Following the anniversary, Ukraine released a new updated atlas of the areas contaminated by radioactive leakage after the explosion at Chernobyl's fourth reactor on the morning of April 26, 1986. This valuable document is experiencing strong soil contamination around Chernobyl cesium-137, strontium-90 and plutonium-238, 239 and 240, and also forecast the level of contamination with americium for the year 2056.
On that date precisely the concentration of americium-241 "will reach its maximum value, resulting from the decay of plutonium-241, according to the atlas. The exclusion zone and the total resettlement area around Chernobyl "never" will be eligible to live in them, according to Mykola Proskura, deputy chief of the department responsible for managing the contaminated territories.
Proskura clarified that the territory in question has a total of 2600 kilometers and "the best may be reduced to 2000 square kilometers, but that will be in the distant future." The official said that "between 1500 and 2000 square kilometers will never be able to live" because "there are radioactive isotopes with a decay period of 24,000 years and due to cesium and strontium will have to wait at least 300 years." The area may be of limited use to the economy, he said, by "holding a clean and requires minimal staff, such as wind energy production." The atlas released yesterday confined to the territory of Ukraine and does not give data or Belarus or Russia, other states like the USSR, were particularly affected by the disaster.
Despite the common nature of the tragedy, since the disintegration of the USSR in 1991, the three Slavic countries have their own approaches and hit records. Fragmentation adversely affects research on the consequences of the accident, according to Western medical sources at the conference.
Belarus and Russia are forming a common register again, but Ukraine has little interest in participating in the company. "Kiev tend to exaggerate their data; Minsk to minimize them and make as if all were overcome, and defend one another piecemeal project financing and putting in place a rigorous prioritization of global common interest," claimed the sources.
Ukraine and Belarus Chernobyl spend about 6% of its annual state budget, according to Jerzy Osiatynski, the International Atomic Energy Agency. There is "clear evidence" of increased numbers of thyroid cancer from radiation exposure to children to iodine 131, as Ausrele Kesminiene, International Agency for Research on Cancer, part of the World Health Organization.
Kesminiere explained that there is also evidence of an increased incidence of leukemia from exposure in utero and an increased incidence of breast cancer. The scientist, however, refused to relate these increases to the accident and to draw quantitative conclusions about the actual impact on the health of the affected population.
"You have to see how to protect themselves, because the nuclear energy development will continue," he said. Scientific studies, which now respond to a "chaotic funding system, should concentrate on the really important data." There are studies that raise more questions than answers. We can not afford these luxuries.
We think that our resources are limited. Chernobyl no is a particular case, but a public health issue and should be a specific mechanism for investigation, "said Kesminiene. In his view, the EU should take the initiative to coordinate research, such as lifetime supervision of a contingent of administrators.
"I could not answer the question about how many people have died because of Chernobyl, because all figures are estimates and are based on different data," said Kesminiene. "In addition, radiation must be separated from other factors such as stress, food quality, people forced from their homes.
Therefore, it is possible to say that the health of millions of people have suffered because of Chernobyl" said. The scientist lamented the lack of cooperation of Belarus on joint studies. An EU project on the impact of the accident at the increasing number of breast cancers could not be realized because Minsk banned the export of biological samples, said.
Viacheslav Shestopálov, director of scientific and engineering center, said that low radiation doses impair the elasticity of the nerves and memory and said that animals living in Chernobyl are not spared of mutations. He also stated that the swallows from Chernobyl zone has 28% chance of reaching the next station, while the swallows of uncontaminated areas are 40% and those of Spain, 45%.
Chernobyl radioactive cloud spread across Europe, including southern France, but stopped in the Pyrenees and did not affect the Spanish territory. For its part, Dmitri Bazika, deputy director of the Center for Radiation Medicine, said that according to Russian forecasts, cases of cancer because of Chernobyl should increase between 3% and 3.5%, and Ukrainians forecast of 8% to 11%.
Data on the effect of low dose intensity in the brain are not tested, he said. "The Japanese were discovered effects of radiation 65 years after Hiroshima, and we continue to find, 65 years after Chernobyl," he said. Under current conditions, the sarcophagus of the fourth reactor can last between 15 and 20 years, "said Volodymyr Jolosha, head of state in charge of managing contaminated land.
The arc must protect the sarcophagus is designed to last a hundred years. The shelter is an arch-engineering building, currently under construction, which will slide over the existing sarcophagus and to be financed with funds collected from donors on Monday. Meanwhile, Ihor Hramotkin, director of the Chernobyl plant said 60% of the space delacentral had been investigated, but could not penetrate the rest of the units and therefore information about these spaces was inaccessible.
