ECS.13 — Chernobyl (1986)

Environmental Systems and Societies · SL / HL · syllabus-mapped notes

1. Overview

   The world's worst nuclear accident: a reactor explosion that turned a low-carbon energy source into a centuries-long contamination problem.

2. Systems and sustainability angle

   Energy-source risk, radioactive half-lives and an exclusion zone: pollution released far faster than any ecosystem can transform it.

3. Management and response

   Evacuation, containment and a global tightening of nuclear safety, weighed against Soviet secrecy and a permanent cost.

4. HL lens angle

   The ethics of waste that outlives its makers, and the environmental law that grew from transboundary fallout.
