Water portal; 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 ...
Radioactive contamination, also called radiological pollution, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition).

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.
A massive sinkhole has been leaking at least 215 million gallons of radioactive water into an aquifer in this state.
In the area around a pressurized water reactor or boiling water reactor during normal operation, a significant amount of radiation is produced due to the fast neutron activation of coolant water oxygen via a (n,p) reaction. The activated oxygen-16 nucleus emits a proton (hydrogen nucleus), and transmutes to nitrogen-16, which has a very short ...
A major radioactive contamination threat to the Columbia River should be removed at the Hanford nuclear site before the end of summer. Hanford workers have started to pump contaminated water from ...
According to the United Nations the normal concentration of uranium in soil ranges between 300 μg kg −1 and 11.7 mg kg −1. [3] It is well known that some plants, called hyperaccumulators , are able to absorb and concentrate metals within their tissues; iodine was first isolated from seaweed in France , which suggests that seaweed is an ...
Naturally occurring radioactive materials (NORM) and technologically enhanced naturally occurring radioactive materials (TENORM) consist of materials, usually industrial wastes or by-products enriched with radioactive elements found in the environment, such as uranium, thorium and potassium and any of their decay products, such as radium and radon.
