The presence of radioactive material necessitates processes that are occupationally dangerous, hazardous to the natural environment, expensive and time-intensive.
en.wikipedia.org C constitutes a negligible part; but, since it is radioactive with a half-life of 5,700 years, it is radiometrically detectable.
en.wikipedia.org After the water evaporates, an invisible base surge of small radioactive particles may persist.
en.wikipedia.org When these safety devices are properly calibrated, maintained, and used, it is virtually impossible for a radiographer to be injured by a radioactive overexposure.
en.wikipedia.org Particles formed from detonations above, or in, the ocean, will contain short-lived radioactive sodium isotopes, and salts from the sea water.

www.uni-kiel.de The abundance of the stable isotope 13C is about 1.11 %, whereas the radioactive 14C is present in only very small quantities of 1.176 x 10-12 atoms per atom 12C.

Die natürliche Häufigkeit des zweiten stabilen Isotops 13C beträgt etwa 1,11 %, die Konzentration des radioaktiven 14C liegt hingegen nur bei ca. 1,176 x 10-12 Atomen je 12C Atom.

www.uni-bremen.de Where the microorganisms only found minimum amounts of sulfate available, the lab cultures retained amounts of methane that were enriched with the lighter isotope carbon 12.
[...][...]
Wenn den Mikroorganismen nur sehr wenig Sulfat zur Verfügung stand, blieb in den Laborkulturen, wie auch im Meeresboden beobachtet, Methan zurück, dass mit dem leichten Isotop Kohlenstoff-12 angereichert war.

www.ptb.de In order to be able to come to a more accurate conclusion here as to how long nuclear waste which contains this isotope will probably radiate, researchers from various institutes have joined forces:
[...][...]
Um eine genauere Aussage darüber treffen zu können, wie lange nuklearer Abfall, der dieses Isotop enthält, voraussichtlich strahlt, haben sich Forscher verschiedener Institute zusammengeschlossen:

www.rptc.de For this procedure, the patient is injected with contrast medium marked with a short-lived radioactive isotope. This enables both precise tumor localization ( CT ) and identification of metabolically active tumor fractions ( with the isotope marking areas of increased metabolic activity in the tumor or metastasis ) to be accomplished in a single session.
[...][...]
Hierbei wird dem Patienten ein Kontrastmittel injiziert, das mit einem kurzlebigen radioaktiven Isotop markiert ist, so dass in einer einzigen Untersuchung sowohl die genaue Tumorlokalisation ( CT ) als auch die tumoraktiven Anteile ( Isotop, durch die erhöhte Stoffwechselaktivität des Tumors bzw. der Metastase ) identifiziert werden.

www.helmholtz-berlin.de For the use in a research reactor one has to enrich the 235U-component in a complicated procedure to a concentration of approximately 20 %; the rest remains the isotope 238U, which does not fission.
[...][...]
Um als Kernbrennstoff in Forschungsreaktoren nutzbar zu sein, wird der 235U-Anteil in einem komplizierten Prozess auf eine Konzentration von etwa 20 % erhöht ( angereichert ); der Rest besteht wieder aus dem Isotop 238U.
