mukaistaisot
Mukaistaisot is a term that appears in some Finnish-language discussions of speculative science and fiction to denote a hypothetical class of engineered isotopes or isotope-like materials that can imitate the behavior of a different isotope for testing, calibration, or educational purposes. The word appears to be a compound of muka, meaning mimic or pseudo, and isotooppi, meaning isotope.
In fictional or speculative settings, mukaistaisot may be described as isotopes whose nuclear properties are altered
Discussions of mukaistaisot thus serve mainly as thought experiments or world-building devices, and they raise questions
