Part E- Descriptions of how isotopes can be used in research, medicine, industry, and electricity generation.

How isotopes are used in research

All that is discussed here is why stable isotopes research works. It has a fairly accurate description of the natural processes that are used by researchers in many different kinds of ways. The earth and its atmosphere is made of diferent elements of different atoms. For example oxygen, carbon, and nitrogen. These all have several forms based upon there atomic weight.(2009, Stable isotopes)

Used in Medicine


C.A.T. Scans for the Dye that is used when the Scan is being done.
The "isotopes" in the C.A.T scans is the dye. which will allow the Tech, and the Doctor to see the area or area's that are highlighted in a the part of the Scan that are affected. This is how
they find the problems, and are fast to diagnose the problem. Some isotopes like
Chromium-51 are used to label red-blood cells.(2009, Wikianswers)






Used in industry



  • Modern industry uses radioisotopes in a many differnet kinds of ways to improve fertile and, in some cases, to gain information that cannot be gained in any other way.

  • Sealed radioactive sources are used in industrial radiography, projection applications and mineral analysis.

  • Short-lived radioactive material is used in flow tracing and mixing measurements.

  • Gamma sterilization is used for medical supplies, some bulk commodities and, increasingly, for food preservation. (2009, Springerlink)


Used in Electricity Generation


Noble gas stable isotope affluence measurements may or may not provide a tool for detecting reprocessing activities of nuclear fuels. An approach has been made by blending calculations of released fission xenon and krypton in air using the Isotope Mixture Programs which have been developed at the IRMM. These have been made by carrying out these calculations. After having obtained a reliable approximation to the expected range of the isotope ratios in the blends and the respectful detection limit there of through these calculations, the potential application of ultra-accurate measurements of the isotopic agreement of anthropogenic and atmospheric noble gases is taken into application. Also the important role of radiometric measurements of 85Kr and 133Xe for the detection of nuclear fuel is taken into account. The information hown by such activity measurements is limited, therefore a method to calculate the initial isotopic composition of released fission noble gases, through measuring of their atmospheric mixing ratio, is presented and discussed. Highly accurate stable isotopic measurements of atmospheric noble gases might provide more detailed information on the "history" of the reprocessed nuclear fuel. So they could serve in combination with radiometric detection techniques. (2009, SpringerLink)
