Radiation is energy that propagates through matter or space. Radiation energy can be electromagnetic or particulate. Radiation is usually classified into non-ionizing (visible light, TV, radio wave) and ionizing radiation. Ionizing radiation has the ability to knock electrons off of atoms, changing its chemical properties….

For anyone whose life is presently dominated and controlled by fears of radiation, and that includes all governments who issue orders for their staff to evacuate Japan, you should not let yourself be ruled by irrational fears and superstitions fueled by sensationalist media hype.
