The primary functions of the Program Area Committee are to analyze mechanisms of interaction of nonionizing radiation with biological systems, including humans, and to identify biological responses and potential human health effects. It must be emphasized that cigarettes and tobacco also contain polonium-210, originating from the decay products of radon, which stick to tobacco leaves. Many researchers believe that doses of polonium-210 are the origin of the high incidence of lung cancer among smokers. Gamma rays are similar to visible light, but have much higher energy. Ionizing radiation has so much energy it can knock electrons out of atoms, a process known as ionization. When these radionuclides are inhaled, they may be deposited on lung tissues (bronchial epithelium), especially in the areas of branching or bifurcation of airways in the lower lung. X-rays and gamma rays have the same basic properties but come from different parts of the atom. Nearby non-smokers inhale the radionuclides as well. A rem is a measure of dose deposited in body tissue, averaged over the mass of the tissue of interest. Dr. O is building an entire video library that will allow anyone to learn Microbiology and Anatomy & Physiology for free.
