Several fluorescent molecules can be used simultaneously (given that they do not overlap, cf. FRET), whereas with radioactivity two isotopes can be used (tritium and a low energy isotope, e.g. 33 P due to different intensities) but require special equipment (a tritium screen and a regular phosphor-imaging screen, a specific dual channel ...
The additional radioactivity in the biosphere caused by human activity due to the releases of man-made radioactivity and of Naturally Occurring Radioactive Materials (NORM) can be divided into several classes. Normal licensed releases which occur during the regular operation of a plant or process handling man-made radioactive materials.
Journal of Environmental Radioactivity is a monthly peer-reviewed scientific journal on environmental radioactivity and radioecology. It was proposed and started by Founding Editor Murdoch Baxter in 1984 and is published by Elsevier .
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).
Tritium is the only radiation source used in radioluminescent light sources today due to its low radiological toxicity and commercial availability. [3] Various preparations of the phosphor compound can be used to produce different colors of light. For example, doping zinc sulfide phosphor with different metals can change the emission wavelength ...
The Journal of Environmental Radioactivity (JER) was the first collection of literature on the subject, and its inception was not until 1984. [2] As demand for construction of nuclear power plants increased, it became necessary for humankind to understand how radioactive material interacts with various ecosystems in order to prevent or minimize ...
This problem is classically addressed by the use of carrier ions. Thus, carrier addition involves the addition of a known mass of stable ion to radionuclide-containing sample solution. The carrier is of the identical element but is non-radioactive. The carrier and the radionuclide of interest have identical chemical properties.
