High-energy ionizing radiation

Addition reactions between isoprene and tetrahalomethanes can be induced by peroxides, high energy ionizing radiation, or other radical-generating...

Researchers claim that high-energy ionizing radiation could be more economical than existing treatment technologies for treating fluorescent light ballasts. 

Only liquified wastes have been successfully destroyed by high-energy ionizing radiation. The technology has only been evaluated in bench-scale tests. 

In the initial bench-scale testing of high-energy ionizing radiation treatment technology, researchers stated that to reduce the level of PCBs to meet federal requirements, a 15-MegaRad... 

The principal commercial initiators used to generate radicals are peroxides and azo compounds. Lesser amounts of carbon-carbon initiators and phoioinitialors. and high energy ionizing radiation are also employed commercially 10 generate radicals. 

Another possibility is to irradiate the monomer with high-energy ionizing radiation such as X-, or (3-, or y-rays, a procedure used in some industrial processes even if the mechanisms by which active centers are generated are not well known. 

Three types of radiation-induced procedures have been used including (a) recoil tritiation, (b) Wilzbach gas irradiation7 with its modifications, and (c) radiation synthesis.8 All these methods utilize high-energy ionizing radiation to achieve tritium incorporation. Wilzbach exchange7 is the most satisfactory of the three and has been the most widely used. Radiation synthesis is a relatively recent development of limited but valuable specificity. 

Prorad Radiation promoter, a compound promoting or enhancing the cross-linking reaction by high-energy (ionizing) radiation. 

Radical-induced oxidation of ascorbate by molecular oxygen probably involves a short chain (45). The overall mechanism or parts of it have been studied primarily by high energy ionizing radiation (45,46) or... 

To be used as a tracer, a radioisotope need emit only low-energy detectable radiation. Many other uses of radioisotopes, however, depend on the damage that high-energy, ionizing radiation can inflict on living systems. 

In thi.s. section we will consider those types of exciting radiation which create many electrons and holes in the luminescent material under consideration. This type of excitation is usually indicated as high energy ionizing radiation. The most well-known examples are cathode rays and X rays, but one can also think of y rays and a particles. It is usually assumed that the excitation process proceeds as follows ...
