Numerous human and agricultural decontamination countermeasures exist for the two most persistent and biologically significant isotopes, cesium-137, strontium-90 and long-lived fallout contamination in general, with the most visible and immediate act that will prevent a potentially large dose to the public, taking the form of using shielded bulldozers to skim off the layer of topsoil that the fallout had settled on, a restorative practice that was fielded upon the creation of Lake Chagan. The creation of human decontamination tents at the entrances of buildings and when lower levels of risk exist, the use of clean room air showers as a form of contamination control to prevent the spread of radionuclides that adhere to dust, into building interiors, would also be advisable to reduce the elevated risk of radiation induced cancer that would otherwise occur. Air showers may be paired with electrostatic precipitators to attract the dust to collection plates, forestalling a re-suspension that may otherwise be inhaled. Moreover use of the open access radioecology research on decontamination and conventional agriculture in the Chernobyl-Polesie State Radioecological Reserve and around the Fukushima accident, would both be implemented in the event of any widespread fallout contamination, with particular emphasis on bioremediation of radionuclides from soil and aquifers. Although less of a hazard than external exposure, internal decontamination, that may be required after assessment in a whole-body counting session, in the long term may, as is now, be conducted with binding-and-excretion promoting chelation therapy, with ammonium-ferric-hexacyano-ferrate (AFCF)/"Giese salt", Radiogardase and DPTA all proven effective.
