Class 12 Biology Environmental Issues Radioactive wastes

Radioactive wastes

  • Radioactive wastes are those which contain radioactive materials.
  • Radiation given off by nuclear waste causes mutations to occur at a very high rate.
  • At high doses nuclear radiation is lethal but at lower doses it creates various genetic disorders such as cancer.
  • Storage of nuclear waste after pre-treatment done in shielded containers buried within the rocks, about 500 m deep below the earth’s surface.
