'S e meatailt trastach glè rèidio-bheò agus fuadain a tha ann.

Rinneadh caractarachd ri 7 iosatòpaichean de roentgenium. Tha ²⁸²Rg, le leth-bheatha 2.1 mionaidean, as seasmhaiche.^[2]

Eachdraidh

Ann an 1994 rinn an sgioba Sigurd Hofmann aig an Comann airson Rannsachadh nan Aidheon Trom ann an Darmstadt ataman roentgenium. Bhuail iad niùclasan biosmat-209 le niùclasan niceal-64 agus rinn iad ²⁷²Rg.
