Australia: join the nuclear ban treaty

Nuclear weapons: evidence for elimination

Evidence shows the development, testing, and detonation of nuclear weapons have devastating short- and long-term effects on the human body.

  • Studies of nuclear test workers and exposed nearby communities consistently show adverse health effects, especially increased risks of cancer
  • The total number of global cancer deaths as a result of atmospheric nuclear test explosions has been estimated at 2-2.4 million
  • The 1945 nuclear attacks on Hiroshima and Nagasaki killed an estimated 214 000 people. In the years that followed, many of the survivors faced leukemia, cancer, or radiation side effects
  • Modelling of the effects of a limited nuclear attack show that there could be no meaningful medical or humanitarian response to the injuries, deaths, or destruction of infrastructure.
