I am a Health Physicist working for the Radiation Safety Branch at the National Institutes of Health. About 80% of all biomedical research requires the use of low level of radioactive materials. In terms of risk vs. benefit, biomedical research is a very good example where the benefit far out weights the risk If you would like to learn more about radioactivity please check out the following pages. You may be surprised at what you learn.
