The first has to do with the quantity of radioactive elements in the tobacco, especially polonium-210 and lead-210. Our main exposure to ionizing radiation in manmade sources is through the use of diagnostic medical exams. I was looking for a simple example of computing the effects of radiation on a human. Alpha particles lack the energy to penetrate even the outer layer of skin, so exposure to the outside of the body is not a major concern. Non-ionizing radiation is described as a series of energy waves composed of oscillating electric and magnetic fields traveling at the speed of light. radiation, flow of atomic and subatomic particles and of waves, such as those that characterize heat rays, light rays, and X rays.

Most people know that cigarette smoke and tobacco contain many toxic substances including tar, arsenic, nicotine and cyanide.The common dangers of cigarettes have been known for decades. Tobacco smoke is a complex mixture of more than 5,300 identified chemicals. My post was motivated by the following information I encountered on the web: The EPA addresses the source of the radiation from tobacco: Naturally-occurring radioactive minerals accumulate on the sticky surfaces of tobacco leaves as the plant grows, and these minerals remain on the leaves throughout the manufacturing process.

Your calculations, although formally correct, do not take into account the dose conversion coefficients, which depend on "parameters such as the inhalation speed through the mouth, the real fraction of radionuclide transferred from cigarette to mainstream smoke, the lung absorption behavior of the radioisotopes inhaled with mainstream smoke, etc" (from Taroni et al. Radioactive materials, like polonium-210 and lead-210 are found naturally in the soil and air. Cigarettes have been known carcinogens for at least 65 years. Evaluations are made of both theoretical and applied aspects of . They help us to know which pages are the most and least popular and see how visitors move around the site. The lead-210 and polonium-210 particles lodge in the smoker's lungs, where they accumulate for decades (lead-210 has a half-life of 22.3 years). In hazard analysis, both E (electrical field) and H (magnetic field) measurements must be considered in addition to the power density (S) measurements.
