What the Thompsons say they found out during their time inside TMI suggests radiation releases from the plant were hundreds if not thousands of times higher than the government and industry have acknowledged -- high enough to cause the acute health effects documented in people living near the plant but that have been dismissed by the industry and the government as impossible given official radiation dose estimates. (tmia.com)
Here, we investigate how a range of relevant dose rates affect metabolomic dose reconstruction at potentially lethal radiation exposures (8 Gy in mice) from an initial blast or subsequent fallout exposures compared to zero or sublethal exposures (0 or 3 Gy in mice) in the first 2 days, which corresponds to an integral time individuals will reach medical facilities after a radiological emergency. (bvsalud.org)
