1986 CE
Environmental impact of the Chernobyl accident
Climate & environment · Contaminación radiactiva · Riesgo tecnológico · Impacto ambiental · Respuesta a desastres
The April 1986 Chernobyl accident released radioactive material and led to deposition and contamination across land, forests, waters, and settlements in different regions. International assessments distinguish intense effects near the reactor from consequences that varied by radionuclide, ecosystem, distance, and time; this entry concerns environmental impact, not an equivalence among all nuclear systems or accidents.
