Is tantalum radioactive
Did you know?
WitrynaAll of the elements have at least one isotope that is radioactive. So, we can say that there is such a thing as radioactive nitrogen, arsenic and tantalum. Some elements have isotopes that are all radioactive. So if you had asked "is thorium radioactive" the answer would be yes, because ALL the isotopes of thorium are radioactive. Witryna20 kwi 2016 · "The tantalum industry has done an outstanding job of embracing this programme," Loch says. "Over 95% of all tantalum smelters from a global standpoint are in the programme." Loch says that, in contrast, some paper and forestry programmes which have been around for 15 to 20 years have achieved perhaps 10%-20% of their …
