In case of a nuclear power plant accident or using nuclear weapons, radioactive methyl iodide is spread in the air. According to EPA (the US Environmental Protection Agency), massive acute inhalation exposure to methyl iodide leads to pulmonary edema. Depression of the CNS, irritation of the lungs and skin, and effects on the kidneys may result in acutely exposed humans. Acute inhalation exposure of humans to methyl iodide results in nausea, vomiting, vertigo, ataxia, slurred speech, drowsiness, skin blistering, and eye irritation. Tests involving acute exposure of rats and mice have shown methyl iodide to have moderate to high acute toxicity by inhalation, and high acute toxicity by ingestion. There are numerous chronic effects of breathing methyl iodide.
ACIEET addresses the risk of spreading methyl iodide. The filtration systems are ready to use special filters that are able to extract most of the methyl iodide from the air. In case of an nuclear accident or hazard, they can be installed within a short period of time (typically less then 2 hours) to protect people in the buildings from adverse impacts of methyl iodide, which corrodes the respiratory tract.
