It can be hard to understand what the release of radiation from Japan’s earthquake-damaged Fukushima Daiichi nuclear power plant means in terms of human health. Are the radiation levels dangerous and, if so, how dangerous. Most reporters put the risk into perspective using words. Cartoonist Randall Munroe and nuclear reactor operator Ellen McManis have put together different ways of illustrating the risk visually, while radio producer Adam Ragusea offers an audio illustration of various radiation exposures.
Minutes after I posted my article today about radiation from the damaged Fukushima Daiichi nuclear power plant not reaching the United States in harmful amounts, I heard a news report about iodine-131 from the plant being detected in rainwater in Massachusetts. Iodine-131 is a radioactive form of iodine. It’s a byproduct of the reaction that [...]
Even though the situation at the earthquake-damaged Fukushima Daiichi nuclear power plant in Japan remains unsettled, the likelihood that radiation released by the crippled power plant will reach the United States is slim. Harvard Health Letter editor Peter Wehrwein talks with Dr. Richard Zane, a disaster planning expert at Harvard-affiliated Brigham and Women’s Hospital, about potassium iodide pills: what they can—and can’t—do, their benefits and hazards, and why Americans should not be stockpiling or taking them.
Several people who read my earlier post about radiation readings at the Fukushima Daiichi nuclear power plant in Japan pointed out that the time period over which the radiation exposure occurs is important. They’re right—the radiation dose and how long you are exposed to it determine how much radiation you are receiving. That is why [...]
