Explosions
Magnetoencephalography
The measurement of magnetic fields over the head generated by electric currents in the brain. As in any electrical conductor, electric fields in the brain are accompanied by orthogonal magnetic fields. The measurement of these fields provides information about the localization of brain activity which is complementary to that provided by ELECTROENCEPHALOGRAPHY. Magnetoencephalography may be used alone or together with electroencephalography, for measurement of spontaneous or evoked activity, and for research or clinical purposes.
Tritium
Tritium is an isotope of hydrogen (specifically, hydrogen-3) that contains one proton and two neutrons in its nucleus, making it radioactive with a half-life of about 12.3 years, and is used in various applications including nuclear research, illumination, and dating techniques due to its low energy beta decay.

Hydrogen
The first chemical element in the periodic table. It has the atomic symbol H, atomic number 1, and atomic weight [1.00784; 1.00811]. It exists, under normal conditions, as a colorless, odorless, tasteless, diatomic gas. Hydrogen ions are PROTONS. Besides the common H1 isotope, hydrogen exists as the stable isotope DEUTERIUM and the unstable, radioactive isotope TRITIUM.
Hydrogen Bonding
Hydrogen Peroxide
Bombs
A weapon designed to explode when deployed. It frequently refers to a hollow case filled with EXPLOSIVE AGENTS.
Hydrogen Sulfide
Radioactive Pollutants
Radioactive substances which act as pollutants. They include chemicals whose radiation is released via radioactive waste, nuclear accidents, fallout from nuclear explosions, and the like.
Explosive Agents
Substances that are energetically unstable and can produce a sudden expansion of the material, called an explosion, which is accompanied by heat, pressure and noise. Other things which have been described as explosive that are not included here are explosive action of laser heating, human performance, sudden epidemiological outbreaks, or fast cell growth.
Terrorism
Nuclear Warfare
Warfare involving the use of NUCLEAR WEAPONS.
Food Contamination, Radioactive
Radioactive food contamination refers to the presence of radioactive substances in food or water supplies, often resulting from nuclear accidents, nuclear weapons testing, or improper disposal of radioactive waste, leading to potential health risks including radiation sickness and cancer upon consumption.
Soil Pollutants, Radioactive
Pollutants, present in soil, which exhibit radioactivity.

Steam
Radioactive Fallout
The material that descends to the earth or water well beyond the site of a surface or subsurface nuclear explosion. (McGraw-Hill Dictionary of Chemical and Technical Terms, 4th ed)

Kazakhstan
I'm sorry for any confusion, but "Kazakhstan" is not a medical term and does not have a medical definition; it is the name of a country located in Central Asia, known officially as the Republic of Kazakhstan.

Radioisotope Dilution Technique
Hydrology
Science dealing with the properties, distribution, and circulation of water on and below the earth's surface, and atmosphere.
Water Pollution, Radioactive
'Water Pollution, Radioactive' is the contamination of water bodies with radioactive substances, typically as a result of human activities such as mining, nuclear power generation, or improper waste disposal, which can lead to harmful health effects in humans and aquatic life due to radiation exposure.
Accidents, Occupational

Norepinephrine
Precursor of epinephrine that is secreted by the adrenal medulla and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers and of the diffuse projection system in the brain arising from the locus ceruleus. It is also found in plants and is used pharmacologically as a sympathomimetic.
Environmental Exposure
Israel
Oxidation-Reduction
A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471).

Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Stereoisomerism
Deuterium
Deuterium. The stable isotope of hydrogen. It has one neutron and one proton in the nucleus.
Computer Simulation
Computational Biology
A field of biology concerned with the development of techniques for the collection and manipulation of biological data, and the use of such data to make biological discoveries or predictions. This field encompasses all computational methods and theories for solving biological problems including manipulation of models and datasets.
Radiation Monitoring
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.

Oxidants
Electron-accepting molecules in chemical reactions in which electrons are transferred from one molecule to another (OXIDATION-REDUCTION).
Catalase
An oxidoreductase that catalyzes the conversion of HYDROGEN PEROXIDE to water and oxygen. It is present in many animal cells. A deficiency of this enzyme results in ACATALASIA.
Groundwater
Liquid water present beneath the surface of the earth.
Cholestanes
Nuclear Reactors
Devices containing fissionable material in sufficient quantity and so arranged as to be capable of maintaining a controlled, self-sustaining NUCLEAR FISSION chain reaction. They are also known as atomic piles, atomic reactors, fission reactors, and nuclear piles, although such names are deprecated. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
