how long until chernobyl is safe

It will take around 300 years for Chernobyl to potentially be made safe and habitable again under the best-case scenario with advances in technology and cleanup efforts. Scientists estimate that radioactive elements like cesium-137, with a half-life of about 30 years, diminish over time, but full safety for human habitation could take centuries, possibly by the year 2286. Significant cleanup phases are projected for around 2046 and 2065, but complete restoration remains a long-term process due to the persistent radioactivity.
