Proportional distribution of the sources of radiation exposure, Radon 43% result, polonium builds up leading to greater and longer exposures to Ch. 8 Ionizing and Non-Ionizing Radiation Flashcards | Quizlet Learn more about radiation sources and doses. At one pack of 20 cigarettes a day, the annual effective dose would be 360 Sv. Using any tobacco product can lead to nicotine addiction. Radiation is the transmission of energy through space and matter. This has the potential to cause harmful effects to people, especially at high levels of exposure. CDC estimates that cigarettes and tobacco use kill more Americans each year than alcohol, car accidents, suicide, AIDS, homicide, and illegal drugs combined. For comparison, 360 Sv per year for a pack-a-day smoker gives an effective dose similar to what everyone receives on the average from outer space at 330 Sv per year or from the ground at 210 Sv per year (Table 2.1). Forum participants say the same deceptive tactics used by the tobacco industry to hide the dangers of cigarette smoking are .

Ionizing radiation is a natural part of the environment in which we live and is present in the earth, buildings, food we eat, and even in the bones of our bodies. doses of radiation is measured using units called, rads (1 gray = 1 During early history biophysics and bioengineering were primarily concerned with ionizing radiation bioeffects and electrophysiology. PAC 8: Nonionizing Radiation. But the tobacco industry could always show scientific reports, showing no correlation between smoking and cancer. Ionizing radiation exposure comes from a variety of sources, including nuclear weapons testing or other activities during military service. A dose of only 300 joules of x-ray or -ray radiation is fatal for the average human, even though this radiation raises the temperature of the body by only 0.001 C. -particle radiation is even more dangerous; a dose equivalent to only 15 joules is fatal for the average human. In addition to chemical, nonradioactive carcinogens, tobacco and tobacco smoke contain small amounts of lead-210 and . Alpha particles () are positively charged and made up of two protons and two neutrons from the atoms nucleus. A unit of measure used to describe the amount of radioactivity in a sample of material. Human exposures to radiofrequency electromagnetic fields can occur from use of personal devices (e.g. Non-Ionizing Radiation (EMFs) - Breast Cancer Prevention Partners (BCPP) Non-ionizing radiation (NIR) refers to electromagnetic radiation that does not have sufficient energy to ionize (remove electrons from) atoms or molecules.
