A variety of occupational risks is known to cause cancer. Every year more than seven million people die of cancer. Forty percent of these cases could be prevented which means that one in every ten cancer deaths is preventable through interventions targeted on exposure in the working environment. The articles in this issue of GOHNET highlight some aspects of the problem and the prevention of occupational cancer. The articles draw your attention to the large number of workers exposed to specific carcinogens such as asbestos, UV radiation, tobacco smoke, as well as to those workers engaged in occupations and. | A reprint from American Scientist the magazine of Sigma Xi The Scientific Research Society This reprint is provided for personal and noncommercial use.

Simon André Bouville and Charles E. Land Prior to 1950 only limited consideration was given to the health impacts of worldwide dispersion of radioactivity from nuclear testing. But in the following decade humanity began to significantly change the global radiation environment by testing nuclear Steven L. Simon received a . in radiological health sciences from Colorado State University in 1985. He has served on the faculties of the University of Utah and the University of North Carolina at Chapel Hill. He spent five years directing the Marshall Islands Nationwide Radiological Study and also participated in the radiological monitoring of the former nuclear test sites at Johnston Island in Algeria and in French Polynesia. Simon joined the National Cancer Institute NCI in 2000 and now focuses on retrospective dose estimation in support of epidemiologic studies of radioactive fallout and occupational exposure in medicine. André Bouville was born in France and obtained his . in physics at the Université Paul-Sabatier in Toulouse in 1970. He served as a consultant to the United Scientific Committee on the Effects of Atomic Radiationfor 30 years and the International Commission on Radiological Protection ICRP for 17 years. Bouville joined the National Cancer Institute in 1984 and has since been heavily involved in the estimation of radiation doses resulting from radioactive fallout from atmospheric nuclear weapons tests and from .
