Study finds Chernobyl 'hot particles' remain unexpectedly stable after 40 years
Researchers from Leibniz University Hannover and the Helmholtz-Zentrum Dresden-Rossendorf analyzed six radioactive fragments ejected during the 1986 Chernobyl reactor explosion. The particles, some fused with zirconium or formed from burning graphite moderator material, proved more physically and chemically stable than previously assumed, according to the team's findings published in the Journal of Hazardous Materials.
