Chornobyl particles remain toxic after 40 years
A recent study has shown that nuclear fuel particles and reactor debris dispersed following the Chernobyl disaster still retain their crystalline structure and radioactive materials effectively, even approximately 40 years after the incident. Analysis of particles ranging in size from 8 to 50 micrometers indicated that some remained relatively stable and could trap radioactive materials within their structure for extended periods, impacting the assessment of radiation risks from the site. The study's findings help scientists understand the evolution of nuclear fuel remnants and analyze potential hazards in contaminated areas. However, they do not suggest that restrictions on the exclusion zone can be lifted quickly, given the sensitivity and precision required in interpreting the results.
