News Latest Technology dangerous than Chernobyl
More than a quarter of a century after the Chernobyl nuclear power plant accident, still felt the effects of this disaster. Radioactive substances found in the environment, food, but experts say poses a higher risk than Chernobyl, and intemperate use of the latest technology.
Ionizing radiation people are exposed continuously. It emits a variety of sources - space, soil, food, drinking water, radionuclides in building materials. sistema All of these different sources of radiation exposure and intensity. For example, the cosmic ray intensity rises is growing. It depends on the geographical latitude. When operating in the 10-11 km altitude of human exposure to ionizing radiation dose can be 30-40 times higher than the human being on Earth.
It is believed that in addition to radiation and not life. Specialists say that the trouble begins when people suffer not natūrialią radiation, and in addition they receive from such an environment after a nuclear accident scattered radioactive objects or in the diagnosis and treatment of certain diseases.
Lithuanian residents receive exposure of a similar size, like other European countries, people. sistema Radiation Safety Center Director Albinas Mastauskas argued sistema that this should not be afraid of: Asia, South America are areas where people are one of nature gets 5 times higher exposure than we are. However, recently it has been estimated that the average annual radiation dose received by the average resident of Lithuania, from 2.6 millisieverts (mSv) increased to 3.4 mSv.
Exposure due to radionuclides in the soil and in the air is about 27 percent. all people received irradiation. The most common natural radiation from human activities does not, but sometimes his actions may have an impact sistema on, for example, the manufacture and use of potassium fertilizers. So the people who work near large accumulations of these fertilizers can get additional sistema exposure.
Another and perhaps the greatest source of natural sistema exposure determinant is radon gas, which can cause respiratory and lung cancer. sistema "After a couple of years we will have a map of Lithuania goals and each resident will be able to tell whether it is at risk from radon exposure," - said A.Mastauskas. Country there are places where the ground is very deep uranium. Due to natural processes it breaks down into radium, and this - to radon gas. They rise to the surface, and if the house foundation leak may accumulate indoors. Radon gas is odorless sistema and colorless, so people may not be aware that the house is dangerous.
"People who entered the slot sealed windows to ventilate the house as often as possible - said the specialist. - Radon is especially dangerous for smokers: evidence that radon lung cancer increases the risk of them 17-20 times. "
Most suffer the risk of exposure of people living in areas of Karst and Biržų Pasvalio areas and the coast, where the glaciers moved some rocks. A.Mastauskas the people who are going to build a house, to seek advice geologists or radiation protection professionals to learn about what they are experiencing risk of radon exposure. Specialists can also advise on how to seal the foundation. "People should sistema build their homes only from certified building materials," - said the leader.
About 20 per cent. all people received exposure consists sistema of exposure experienced medical diagnostic procedures. X-ray, a person normally receives exposure of less than 1 mSv during radioscopy - about 3 mSv, since the procedure takes considerably longer. The maximum exposure experienced by computerized tomography. Republican Vilnius University Hospital Radiology Department Raminta Šydeikienė added that exposure depends on which part of the body being studied. In, for example, the head of the investigation, exposure of a small, but if examined the thorax or abdomen, one at a time can get a dose, that comes from the environment in about five years.
"People are looking for love in order to make a deposit of computerized tomography, although the diagnostic x-rays would be sufficient. Lithuania is about 60 computed tomography, and their exposure is as much as 60 percent. all medical devices emitted radiation exposure. X-ray machines have more than 2 000. The new technology must be used when there are no other options, "- convinced A.Mastauskas.
Medics perioperative patients, trying as much as possible to protect them from jonizuojančiųjų rays. As a result, for example, the most sensitive parts of the body - skydlaukė, or sexual or other
