Further work


Production of californium for a commercial order using the Oak Ridge National Laboratory high-flux reactor in Tennessee allowed the separation of berkelium-249 for the production of tennessine in Dubna. After successfully synthesizing tennessine and enough of the bekelium-249 had decayed to californium-249, the scientists at Dubna were able to confirm their earlier synthesis of oganesson.
