Global conflict involving countries of Europe, Africa, Asia, and North America that occurred between 1939 and 1945.

Pollutants, present in air, which exhibit radioactivity.

Leukemia produced by exposure to IONIZING RADIATION or NON-IONIZING RADIATION.

The observation, either continuously or at intervals, of the levels of radiation in a given area, generally for the purpose of assuring that they have not exceeded prescribed amounts or, in case of radiation already present in the area, assuring that the levels have returned to those meeting acceptable safety standards.

Plutonium. A naturally radioactive element of the actinide metals series. It has the atomic symbol Pu, atomic number 94, and atomic weight 242. Plutonium is used as a nuclear fuel, to produce radioisotopes for research, in radionuclide batteries for pacemakers, and as the agent of fission in nuclear weapons.

The amount of radiation energy that is deposited in a unit mass of material, such as tissues of plants or animal. In RADIOTHERAPY, radiation dosage is expressed in gray units (Gy). In RADIOLOGIC HEALTH, the dosage is expressed by the product of absorbed dose (Gy) and quality factor (a function of linear energy transfer), and is called radiation dose equivalent in sievert units (Sv).

Warfare involving the use of living organisms or their products as disease etiologic agents against people, animals, or plants.

Weapons that are capable of a high order of destruction and/or of being used to destroy large numbers of people. It includes NUCLEAR WEAPONS, and biological, chemical, and radiation weapons.
