Intriguing discovery in the Chernobyl zone – what German scientists found

German researchers analyzed six microscopic radioactive particles from the Chernobyl exclusion zone and found that their crystal lattice remained almost intact 40 years after the disaster. This means that hazardous elements enter the soil more slowly than previously assumed.

A group of German researchers collected and analyzed six microscopic hot particles from the Chernobyl exclusion zone. The particles, ranging in size from 8 to 50 micrometers, were collected at various points in the zone. Laboratory analysis, the results of which were published in the Journal of Hazardous Materials, showed that the crystal lattice of most samples remained almost intact 40 years after the 1986 disaster. This means that dangerous radioactive elements are securely held within the structure and enter the surrounding soil much more slowly than previously assumed. The researchers divided the found fragments into three categories: fuel that retained the structure of uranium dioxide; elements in a protective shell of zirconium; and particles affected during a severe fire at the reactor. The scientists caution against premature generalizations, as additional large-scale studies will be required to assess the environmental situation across the entire region.
