Epidemiology is the study of the distribution of disease in populations and of the factors that affect this distribution. In contrast to clinical medicine where the emphasis is on the individual, epidemiology involves the examination of patterns of disease in groups of individuals. While epidemiology originated from investigations of epidemics of infectious diseases in the 19th century, epidemiological research in western countries is now directed largely at chronic diseases, such as heart disease and cancer. Indeed, epidemiology has played a vital role in identifying and quantifying the health risks of cigarette smoking and exposure to agents such as asbestos, as well as radiation. http://www.hpa.org.uk/radiation/faq/epidemiology/epid1.htm
