Mi-shell heavy Air Max 2011 Black Purple natural radionuclides Jiao Online Nike Shoes India store, especially native radionuclides. Mi-shell radioactive material in the main Jiao Department of Huo Dian thorium for uranium, of which natural radionuclides in the Nike Elite Shox Flight Green air are the main Jiao Die Form release people the atmosphere and its daughter nuclides, animal and plant food in the most natural radionuclides in soil from the main Jiao Huo Yan Shi of weathering and erosion generated, we can see where the radioactivity is transferred from the rock Shi due to many different types of rock Shi, by the natural conditions are not the same degree of effect can be expected in natural soil the Air Max 2011 Black Purple concentration of radionuclides is a great New Nike Sb Blazers range of soil geographic location of Mi Dian Dian Mi quality source of Dian climate and hydrological conditions are affecting the agricultural history of natural radionuclides in soil content of Nike Basketball Socks Orange heavy Jiao factors present in the rock Shihuo radioactive substances in soil, leaching into the water as Mi role losses, Mi natural radionuclides in water in this way from the main Jiao addition, Nian soil particles attached to Die on the table of radionuclides in the wind under the action of the gas can be dissolved into dust Ge Liao, and then transferred to the atmosphere and further plants Ge animals migrate to soil in some of the soluble radionuclides absorbed by plant roots, then transported to the edible Bu points, access Zhuo again herbivores feed, and then transferred to the predator, the human body eventually become food Huo Jiao radionuclide source of heavy Environmental concentrations of natural radionuclides in water with a Air Max 2011 Black Purple variety of factors. In addition, natural Bao also Air Max 2011 Black Purple includes radioactive cosmic rays. cosmic rays from space hitting a ball on the Mi Hao energy particle flow, which consists of particles composed of protons Dian of natural radioactivity has been adapted for humans, did not cause any harm. 2 Dian radon on the human body what harm? radon tom enter the body through respiration, decay Shi short-lived radionuclides produced by Shen Ji will be in the bronchial lung Huo Dian renal tissue. When these short-lived radioactive decay Shi, released from the particles maximum irradiation damage, make a change of respiratory epithelial cells by radiation exposure may cause long-term in vivo tissue damage Bureau of Bu, or even induced lung Huo bronchial carcinoma. It is estimated that a person's lifetime, if the radon concentration 370Bq / m3 chamber who live in an environment, there will be 30-120 per thousand died of lung cancer. radon and its progeny, which decay with Shi Shi will release a very stubborn penetrating rays, external beam radiation on the human
