Researchers analyzing six highly radioactive fragments from the Chernobyl reactor found that the particles’ crystal structure has remained largely intact, suggesting the fuel is more chemically stable than expected. The study could help refine estimates of how long these particles retain radionuclides and what risks they pose, though the authors caution that results from a small sample set can’t be generalized to all Chernobyl debris.
