Human exposure to radiation is often measured in rems (roentgen-equivalent man), or millirems (mrem). The cancer risk caused by exposure to radiation is thought to be approximately 1 fatal cancer per 8,000 person-rems of exposure (e.g., 1 cancer death if 8,000 people are exposed to 1 rem each, or 10,000 people exposed to 0.8 rems each, etc.). (a) Natural radioactivity in the environment is thought to expose us to roughly 130 mrem / yr. How many cancer deaths in the United States (population 260

To demonstrate their power, he produced t
