All levels of radiation exposure are associated with increased risks of long-term genetic damage and increases in cancer, proportional to the dose. Acute symptoms are increasingly likely at acute doses above a few hundred mSv without intensive medical care, doses around 4 Sv (4000 mSv) will be fatal for many of those exposed. Acute exposures over 100 mSv produce effects on chromosomes measurable in laboratory testing.

101, 322.ġ23 The average global background level of radiation we are all exposed to from inhalation of radon gas produced by the decay of uranium in the Earth's crust, cosmic sources, soil and rocks, and ingestion, is about 3 mSv per year.

After conducting an explicit series of nuclear weapons test explosions in 1998, India admitted that its 1974 explosion had also been a nuclear weapon test. The best-known case of deceitful use of the designation of PNE is that of India's 1974 explosion. Because PNEs were widely regarded as a “back door” for nuclear weapons, they are prohibited under the CTBT. 3 The explosive device used for a peaceful nuclear explosion (PNE) is the same as for a weapons test, and the adverse effects on health and the environment are the same (see CTBTO Preparatory Commission, Peaceful Nuclear Explosions, available at: In addition, there is no objective way to verify that a nuclear explosion designated as “peaceful” does not have some military purpose.
