# Isotopen van renium

Het chemisch element renium (Re), met een atoommassa van 186,207(1) u, bezit 1 stabiele isotoop: $^{185}$Re, met een abundantie van ongeveer 37,4%. Deze isotoop wordt ervan verdacht via α-verval te vervallen tot de stabiele isotoop $^{181}$Ta. Daarnaast komt in de natuur ook de radio-isotoop $^{187}$Re voor, die een halfwaardetijd van 41 miljard jaar bezit en tevens de meest voorkomende isotoop van dit element is (ongeveer 62,4%). Ook indium en telluur vertonen dit verschijnsel.
Renium-187 is ook een primordiaal radionuclide, dat in de geochronologie wordt gebruikt in de renium-osmiumdatering van zeer oude gesteenten. De overige 32 radio-isotopen zijn onstabiel en hebben een relatief korte halfwaardetijd (de meeste minder dan een seconde).
De kortstlevende isotoop van renium is $^{160}$Re, met een halfwaardetijd van ongeveer 860 microseconden. De langstlevende is $^{187}$Re, met een halfwaardetijd van 41 miljard jaar.
