The document discusses the potential health effects of radiation exposure from two types of radiation: ionizing and non-ionizing. Ionizing radiation from sources like X-rays and nuclear accidents can cause health issues like nausea, hair loss, and even death at high levels of exposure. While the Fukushima nuclear accident did not involve the same magnitude of radiation as the atomic bomb in Hiroshima due to differences in the type of radiation released, it still posed health risks to nearby residents that the Tokyo Electric Power company needs to take responsibility for addressing.
