  • Geological and meteoritic dating by radioisotopic methods (lead/uranium, potassium/argon, etc.) are all untrustworthy.

Examples

  • The radioisotopic dating of most meteorites indicates that they formed about 4.6 billion years ago, a date that is thought to signify the beginning of the solar system.

  • Advanced radioisotopic power systems under study would operate not only in the vacuum of space but also on planetary surfaces with atmospheres.

  • So we've already mentioned radioisotopic labeling as a way of quantitating using various radioactive sulfur.

  • Radioisotopic dating of most meteorites indicates that they formed about 4.6 billion years ago, a date that is thought to signify the beginning of the solar system.

    Academic text (1990)
  • The real age of our planet—about 4.5 billion years—was finally accepted in the 1950s after refinement of several radioisotopic age-dating techniques.

    Academic text (1990)
  • Using radioisotopic tracers and autoradiographic imaging at ANSTO, the investigators were able to visually identify the sites in the tadpoles where selenium had accumulated.

  • Many studies rely on radioisotopic techniques to trace the movement of pollutants in the environment.

Morphology

radioisotopic = radioisotope (transparent) = radio + isotope + ic

Formed by straightforward addition of the adjectival suffix '-ic' to the noun 'radioisotope', so the meaning is directly derived.

Etymology

Radioisotopic combines radio- and iso- from isotope. The radio- part means 'ray' or 'to send out rays', as in radiate, and iso- means 'same', so isotope names different versions of the same element. So radioisotopic describes radioactive versions of an element, which is why we use radioisotopic methods for dating and as tracers.
