Applications Roentgenium does not have any known application and little is known about it. Roentgenium in the environment Roentgenium is not found free in the environment, since it is a synthetic element. |
Health effects of Roentgenium
As it is so unstable, any amount formed would decompose to other elements so quickly that there’s no reason to study its effects on human health.
Environmental effects of Roentgenium
Due to its extremely short half-life (about 1.5 milliseconds), there’s no reason for considering the effects of roetgenium in the environment.Back to chart periodic elements
