‘Although oxygen data might conceivably be affected in this way, radiogenic isotopes should not and for these there is no strong correlation with any major element parameter.’
‘Over time these original ratios will become modified as more and more of the parent isotope turns into the radiogenic daughter isotope.’
‘It is nevertheless significant that at most only 15-20% of Uranus' internal energy is estimated to be from radiogenic heating.’
‘In addition to microbiological testing, dust samples are screened for the presence of heavy metals, pesticides, and radiogenic elements.’
‘Once the melt has crystallized, radiogenic argon accumulation recommences.’
‘Because of their large rural populations these areas generally lack health care services needed to screen and treat radiogenic diseases.’
‘Pb isotope studies showed that the minor sub-Waulsortian mineralization is significantly less radiogenic than that of the main mineralization, implying two different sources for lead.’
‘He explained that the two known sources of heat: radiogenic heating and tidal heating, are not enough, either alone or in combination to account for the behaviour.’
‘It is therefore likely that the radiogenic lead content in these rocks is also the result of a contribution from a subducted sedimentary component.’
‘However, some of the age variation may record a real uneven distribution of radiogenic argon.’
