Hrayr Karagueuzian on radioactive particles in cigarettes
Показать описание
Tobacco companies knew that cigarette smoke contained radioactive alpha particles for more than four decades and developed "deep and intimate" knowledge of these particles' cancer-causing potential, but they deliberately kept their findings from the public, according to a new study by UCLA researchers.
The analysis of dozens of previously unexamined internal tobacco industry documents, made available in 1998 as the result of a legal settlement, reveals that the industry was aware of cigarette radioactivity some five years earlier than previously thought and that tobacco companies, concerned about the potential lung cancer risk, began in-depth investigations into the possible effects of radioactivity on smokers as early as the 1960s.
Dr. Hrayr S. Karagueuzian first author of the study and an adjunct professor of cardiology who conducts research at the UCLA Cardiovascular Research Laboratory, part of the David Geffen School of Medicine at UCLA, discusses his research.
