Here is a bit of background: Unstable atoms give off energy as their nuclei spontaneously decay. When this energy is a radioactive element [and there are many, each with a different half life] and sufficiently strong enough to actually dislodge electrons from other molecules or other atoms in its path, it actually can damage or kill any living tissue. This is called ionizing radiation; and it is this that is so deadly –especially for some radioactive elements that have a long half-life (such as Plutonium-239 with 24,000 years, and Uranium-235 with 700-million years). These and many more radioactive elements are continuing to come across the Pacific and hitting everything in North America, and then traveling to Europe and beyond. Nothing is even remotely fixed at the Fukushima Nuclear Reactors facility.
