The decay products include radioactive elements lead-210 and polonium-210. Even though alpha particles are very energetic, they are so heavy that they use up their energy over short distances and are unable to travel very far from the atom. All matter is constantly bombarded with radiation of both types from cosmic and terrestrial sources. Additionally, like PAC 8: Nonionizing Radiation. Our main exposure to ionizing radiation in manmade sources is through the use of diagnostic medical exams. Laboratory for ionizing radiation; Laboratory for non-ionizing radiation; Health data . 210Po emits alpha particles, which have a weighting factor of 20 relative to x-rays. Many researchers believe that doses of polonium-210 are the origin of the high incidence of lung cancer among smokers. Tobacco used to make cigarettes and other tobacco products contains small amounts of radioactive materials. Radioactive elements emit ionizing radiation as their atoms undergo radioactive decay. Beta-emitters are most hazardous when they are inhaled or swallowed. Major byproducts of the detonation of a nuclear weapon is radioactive fallout. work is the author's own and that Stanford University provided no input Source of Radiation in Tobacco 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. This type of radiation can easily penetrate, but rarely deposit energy in tissue. Learn more about radiation sources and doses. Other examples of ionizing radiation include alpha, beta, and gamma rays from radioactive decay. Food/water 8% and/or gamma raysgamma raysA form of ionizing radiation that is made up of weightless packets of energy called photons. Human exposures to radiofrequency electromagnetic fields can occur from use of personal devices (e.g. adolescent exposures other than ionizing radiation [2]. Donatella Desideri and colleagues (2007) estimated that 20 cigarettes would result in an inhalation of 80 +/- 30 mBq each of polonium-210 and lead-210. During early history biophysics and bioengineering were primarily concerned with ionizing radiation bioeffects and electrophysiology. However, few people know that tobacco also contains radioactive materials: polonium-210 and lead-210. Children's developing lungs are more easily damaged by secondhand smoke.
