  • Radionuclides are often used in radiation therapy to target and destroy cancer cells.
  • radionuclide ventriculography
  • radionuclide scan
  • detect radionuclides

So greens and things that uptake radionuclides from the soil, like Moss and mushrooms are totally off limits in a large range of this area.

Examples

  • The detection of radionuclides in soil samples indicated contamination from nearby industrial processes.

  • The importance of radionuclide bone imaging studies has diminished since MRI became widely available.

  • But anyway, you can see how this these radionuclides spread worldwide pretty quickly.

  • Further epidemiologic studies should show whether exposure to radionuclides from food and water also contributed to these effects.

    Academic text (1990)
  • A matrix removal procedure was thus undertaken to purify target radionuclides from a raw urine sample.

    Academic text (2018)
  • The maximum deposition on Earth's surface of radionuclides from those explosions took place in 1964.

    Academic text (1999)
  • For forty years, scientists knew that radionuclides from reactors along the Columbia River accumulated in body tissue.

    Academic text (1990)
  • Reindeer herding communities can be particularly vulnerable because reindeer accumulate radionuclides efficiently through eating lichen.

    Academic text (2003)
  • Radiological contaminants in drinking water often result from the leaching of naturally occurring radionuclides in geologic structures into groundwater supplies.

    Academic text (1994)
  • Researchers studied the effects of radionuclides on human health after the nuclear accident.

radionuclide singular
radionuclides plural

Morphology

radionuclide = nuclide (semi-transparent) = radio + nuclide

Formed by the combining form 'radio-' (relating to radiation) + 'nuclide', but 'radio' can be ambiguous to learners and 'nuclide' is a technical term.

Etymology

Radionuclide combines radio- (from a Latin word meaning 'ray', the same idea as in radiation) and nucleus (a Latin word meaning 'core', like the 'nucleus' of a cell). So a radionuclide is an atom whose 'core' gives off 'rays', which is why the word means a radioactive atom used in medicine and science.
