Radioactive fallout from a nuclear reactor can be considered in two groups: isotopes of the noble gases (xenon, krypton-133) are radioactive elements with a very low chemical reactivity, relatively short half-lives, are not retained by the body and they remain and become dispersed in the air without ground deposition. (apjjf.org)
The second and more dangerous radioactive fallout group is represented by mainly the radioactive isotopes of iodine, cesium, and tellurium. (apjjf.org)

The source of the radioactive leak at the earthquake-stricken Fukushima Daiichi nuclear power plant was finally identified by the facility's operator TEPCO to be in the primary containment vessel of reactor 3, authorities reported. (rt.com)
While it is possible to remove the radioactive fuel at this time, TEPCO wants to first plug the leak and fill up the space with more water as an additional measure against radiation. (rt.com)
TEPCO is currently in talks with local authorities about releasing the groundwater. (rt.com)
But the water buildup continues, and the short-term storage tanks that TEPCO has been relying on in the past are no longer a solution, so the operator is to set up a bypass system to prevent further buildup of the other, highly radioactive groundwater. (rt.com)
