... But two years after the accident, Japanese scientists discovered a new type of highly radioactive microparticle in the exclusion zone around the Fukushima plant. The microparticles, which had been ejected from the Fukushima reactors, contained extremely high concentrations of cesium 137—a radioactive element that can cause burns, acute radiation sickness, and even death. Satoshi Utsunomiya, an environmental radiochemist from Kyushu University in southwestern Japan, soon found that these particles were also present in air filter samples collected in Tokyo in the aftermath of the Fukushima accident.
The controversy surrounding his attempts to publish his findings nearly cost him his career and prevented his results from being widely known by the Japanese public ahead of the 2020 Summer Olympics in Tokyo.[1] Scientists still don’t know if these highly radioactive microparticles present significant danger to people ...
