Tritiated water is a radioactive form of water in which the usual protium atoms are replaced with tritium atoms. In its pure form it may be called tritium oxide (T 2 O or 3 H 2 O) or super-heavy water. Pure T 2 O is a colorless liquid, [1] and it is corrosive due to self-radiolysis. Diluted, tritiated water is mainly H 2 O plus some HTO (3 HOH).
Liquid water and ice emit radiation at a higher rate than water vapour (see graph above). Water at the top of the troposphere, particularly in liquid and solid states, cools as it emits net photons to space. Neighboring gas molecules other than water (e.g. nitrogen) are cooled by passing their heat kinetically to the water.
Radiation chemistry is a subdivision of nuclear chemistry which studies the chemical effects of ionizing radiation on matter. This is quite different from radiochemistry, as no radioactivity needs to be present in the material which is being chemically changed by the radiation. An example is the conversion of water into hydrogen gas and ...
The WHO/UNICEF Joint Monitoring Program (JMP) for Water Supply and Sanitation [82] is the official United Nations mechanism tasked with monitoring progress towards the Millennium Development Goal (MDG) relating to drinking-water and sanitation (MDG 7, Target 7c), which is to: "Halve, by 2015, the proportion of people without sustainable access ...
Glovebox. Radiochemistry is the chemistry of radioactive materials, where radioactive isotopes of elements are used to study the properties and chemical reactions of non-radioactive isotopes (often within radiochemistry the absence of radioactivity leads to a substance being described as being inactive as the isotopes are stable).
All the common words, idioms, proverbs, and modern academic, literary, scientific, and technical terms of the Urdu language have been listed. Only those obsolete words and idioms have been included which are found in ancient books. They are indicated by the symbol "Qaaf".

The Clean Drinking Water for All Programme/Clean Drinking Water Initiative aim to improve the quality of drinking water by building water treatment facilities. The US$8.2 million Clean Drinking Water Initiative, approved in 2004, provides for the construction of 445 water purification plants of 2,000 gallons per hour in all Pakistani tehsils ...
Drinking water quality standards describes the quality parameters set for drinking water. Water may contain many harmful constituents, yet there are no universally recognized and accepted international standards for drinking water. Even where standards do exist, the permitted concentration of individual constituents may vary by as much as ten ...
