The World Health Organization (WHO) also organizes annual conferences. However, WHO is gagged by the IAEA (per Agreement WHA 12-40 of 1959) and is prohibited from independently issuing statements regarding the health effects of atomic accidents.
This means the IAEA’s engineers and physicists are given the legal right to make statements about the health impacts of atomic accidents at the same time medical doctors from the World Health Organization are legally prohibited from doing so. The IAEA’s physicists issue official statements about the biological effects of exposure to radiation or radioactive contamination; they are permitted to assess the impact of accidental exposure or releases of radioactive contamination on human health.
The IAEA has a history of denying that the following health impacts occurred as a result of exposure to radiation and radioactive contaminants: damage to the immune system, stillbirths, thyroid cancer in children, brain damage, mental retardation, trisomy 21, diabetes, fetal abnormalities, disabled children, and all kinds of cancer, illness.
Many of these illnesses occur months, years or decades after initial or continued exposure and therefore, the IAEA and WHO artificially reduce the casualty count by including only those injuries received in the first minutes, hours, days following a nuclear accident.
