Since Dubnium is not produced in high amounts and it does not exist even on the earth’s crust. Hence there are no such practical applications of this metal apart from the research areas.
The metal has not also proved any harmful effects on health and the environment since it tends to decompose within a short period.
The metal behaves as a solid at temperatures of 20o °C. It occurs as a synthetic element in nature, and it is artificially produced by the bombardment of the californium-249 with the nuclei nitrogen-1.
Dubnium is a highly radioactive element with only one single stable isotope dubnium-268 which has a half-life measuring about only 32 hours and gets decayed through the process of spontaneous fission. The other isotopes are synthetic in nature and have their mass numbers ranging from 256 to 270.
The metal is produced in small amounts artificially. The bombardment of it can make many isotopes of it with the Heavy Ion Linear Accelerator.
