Structurally, [flubromazepam] is closely related to clonazepem and phenazepam... Currently, flubromazepam has no medicinal use and is exclusively manufactured for illicit use. Like other benzodiazepines, flubromazepam elicits sedation, impaired coordination, respiratory depression, muscle relaxation, and CNS [central nervous system] depression. One of the dangerous characteristics of flubromazepam is its extremely long elimination half-life of 106 hours. 2, record 1, English, - flubromazepam

Tritium is a hydrogen atom that has 2 neutrons in the nucleus, in addition to its single proton, giving it an atomic weight near 3. Although tritium can be a gas, its most common form is in water, because, like non-radioactive hydrogen, radioactive tritium reacts with oxygen to form water. Tritium replaces one of the stable hydrogens in the water molecule, H2O, and is called tritiated water. Like H2O, tritiated water is colorless and odorless. Tritium has a half-life of 12. 3 years and emits a very weak beta particle. 4, record 15, English, - tritiated%20water

Low-level radioactive waste (LLW) is composed of a variety of substances that are generated by a large number of processes. Due to this heterogenous mixture, there is no universally accepted classification scheme.

The Task Force's assessment of this problem led it to develop its own definition and classification system, based primarily on the specific activity and half-life of the materials involved. First, it defined low-level radioactive waste as being : all those radioactive wastes, other than spent fuel, arising from the mining, milling, refining or use of materials containing radionuclides.

According to the Oxford English Dictionary and the Webster Third New International Dictionary of the English Language "radiocarbon" refers to any radioactive isotope of carbon and hence has a more general sense than "carbon-14". They point out, however, that "radiocarbon" refers specifically to the carbon-14 isotope.

Thorium(chemical symbol Th) is a naturally-occurring radioactive metal found at very low levels in soil, rocks, and water. It has several different isotopes, both natural and man-made, all of which are radioactive. The most common form of thorium is thorium-232, found naturally.... Thorium-232 has a half-life of 14 billion(14 x 109) years, and decays by alpha emission, with accompanying gamma radiation. Thorium-232 is the top of a long decay series that contains key radionuclides such as radium-228, its direct decay product, and radon-220....

The stability of an enzyme... usually refers to the conformational stability of the protein. The thermal, organic solvent, urea, pH, and storage stability of an enzyme are largely determined by its conformational stability, and inactivation is caused primarily denaturation... The stability of a biocatalyst is usually expressed by means of a half-life value, i. e. the time required for the activity of the reactor to fall to half of its initial activity. It is obviously desirable for the activity to be as stable as possible so that enzyme production and immobilization need only be carried out at infrequent intervals. 2, record 27, English, - stability

Constituents of the waste material are a mix of long- and short-lived radioisotopes. Some have radioactive decay half-lives of no more than tens of years, while others must be isolated from the biosphere for many thousands of years. Dividing the high-level waste into actinides and fission products (a process called partitioning), would permit managing the materials as separate classes. 3, record 59, English, - short%2Dlived%20radioisotope
