How does nuclear radiation to health?

Madrid. .- The radiation "or see or smell, but its effects are long term and will damage the health and the environment for years," and describes the consequences of a nuclear accident in central Japan, Eduard Rodríguez-Farré, radiation biologist Superior Council for Scientific Research. In an interview with EFE, Rodríguez-Farré, Institute of Biomedical Research of Barcelona, \u200b\u200bhas said that fellow scientists have already measured pollutants such as iodine and cesium in the radiation released in Fukushima, which already has partial melting of two of their reactors to the lack of refrigeration caused by the earthquake and tsunami that have hit the country.

"At the core of a nuclear reactor there are more than 60 radioactive contaminants from uranium fission, a very long life and other very short-lived, but almost everyone has a great affinity with our body and accumulate in it, because they are similar to our biological elements, "explains the scientist.

Rodríguez-Farré, a major international nuclear radiation expert and author of studies on the consequences of the Chernobyl nuclear disaster, said that among those 60 pollutants, which would have major consequences for human health would be iodine, strontium 90 and cesium (C-137). "Iodine affects immediately and stop mutations in the genes, from which you can then develop thyroid cancer," says toxicologist, who recalls that the Chernobyl accident multiplied by ten cases of thyroid cancer in central Europe.

For its part, "strontium accumulates in the bones at least 30 years, like calcium, and for years continues to radiate the body, while cesium is deposited in the muscles." Both pollutants "increase the risk of all types of cancer, especially bone, muscle and brain tumors, decrease the body's immunity and increase the capacity of having other diseases." Moreover, "reproduction alters radiation, also referred to this doctor, member of the Scientific Committee of" New health risks "of the European Union, and" affects more women than men.

" The explanation is that "the sperm is completely regenerated every 90 days and altered sperm disappears in that period, but the eggs are in ovary throughout life, and altered if an egg is fertilized by radiation then there malformations fetus, even years later. " The environmental consequences are not minor: "A long-term nuclear contamination is deposited on the ground and at sea, and enters the food chain, fish that are the staple diet in Japan, other animals, plants, fruit, vegetables ...".

This process, argues the scientist, "will bioaccumulate, ie passes from one living thing to another and getting worse" and an example is that of "thousands of reindeer that had to be slaughtered in the Arctic after Chernobyl because they were totally contaminated by lichens had eaten. " Regarding measures taken to prevent radioactive contamination, Rodríguez-Farré said that contact with the skin can be removed by washing with the same zeal that has a surgeon when he enters the operating room: cleaning and brushing the body hair and nails with detergent, and put away clothes.

More difficult is to fight the main route of contact with the contaminants, "inhalation", which almost exclusively to the iodine tablets are effective as the Japanese authorities are distributing to the public. "The thyroid when it is full of iodine eliminated that surplus, so if you saturate the thyroid iodine-normal with those pills," aid to inhale radioactive iodine if you remove it quickly, "he says.
