As Radiation Now 400 Times Normal 40 km From Fukushima, A Closer Look At The Three Most Dangerous Radioactive Isotopes: "With much confusion over just which radioactive isotopes are considered dangerous following the Fukushima explosions, Reuters has compiled a handy overview of the key actors: iodine-131, caesium-134 and caesium-137. For the time being only the far more inert and shorter half-life elements such as Xenon have been dispersed globally, while the more dangerous isotopes have been relatively localized, and their dispersion is limited to wind direction. Furthermore, metrics such as halflife are relatively irrelevant for now since the release of radiation continues mostly unabated thereby producing a constant source of freshly radioactive substances. This is all the more validated by the just released NHK data indicating a surge in radioactivity as far away as 40 kms from the plant: 'Japan's science ministry says radiation exceeding 400 times the normal level was detected in soil about 40 kilometers from the troubled Fukushima Daiichi nuclear power plant."
