Hard to know what to make of this as it is not my field. But here is a claim for element 122, or maybe 124, detection in thorium by a mass spectrometric method. The authors have claimed previously the observation of very heavy isotopes, for instance Rg isotopes in the mass spectra of natural gold.

Abstract: "Evidence for the existence of a superheavy nucleus with atomic mass number A=292 and abundance (1-10) x 10-12 relative to 232Th has been found in a study of natural Th using inductively coupled plasma-sector field mass spectrometry. The measured mass matches the predictions for the mass of an isotope with atomic number Z=122 or a nearby element. Its estimated half-life of t1/2 <= 108 y suggests that a long-lived isomeric
state exists in this isotope. The possibility that it might belong to a new class of long-lived high spin super- and hyperdeformed isomeric states is discussed."
