There are two kinds of radiation: non-ionizing radiation and ionizing radiation. Ionizing activity can alter molecules within the cells of our body. My analysis assumes that the smoker has reached steady state. Exposures normally occur in the far field where the E (electric) and H (magnetic) fields are strongly coupled. 210Po is generated as a decay product from 222Rn. Examples of this kind of radiation are radio waves, visible light and microwaves. Heat (destruction or injury by high temperatures or fire) The amount retained in the lungs depends on the particle size and other factors.
Both thermal and photochemical (biological) effects are possible from exposures (depending on wavelength). Ionizing radiation comes from x-ray machines, cosmic particles from outer space and radioactive elements. Classified as a Class A carcinogen You can test your home or building to determine whether you or your family is at risk of high levels of radon exposure. Low frequency sources of non-ionizing radiation are not known to present health risks. All matter is constantly bombarded with radiation of both types from cosmic and terrestrial sources. Ionizing radiation includes radon, x-rays, gamma rays, and other forms of high-energy radiation. Ionizing radiation exposure of the population of the United States. When radioactive, it releases energy in the form of
