Bohrium is a research-only transactinide with no mine supply, refining base, reserves, or price series. Its commercial reality is the absence of commerce: laboratories make individual atoms in accelerator campaigns to probe nuclear stability, decay chains, and the chemistry of the superheavy region.

The accepted discovery route is GSI Darmstadt's 1981 production of element 107 via chromium-on-bismuth bombardment. IUPAC formalized the name bohrium and symbol Bh in 1997, and IUPAC's present periodic table identifies mass number 270 as the longest-lived confirmed bohrium nuclide. NNDC ENSDF shows a corresponding "270BH A DECAY (1.0 M)" dataset, supporting the one-minute order-of-magnitude lifetime used in this record.
