How can a scientist assess whether a pure niobium (Nb) sample is responsible for contaminating the lab with radioactivity? Test the niobium sample to see whether it now contains other elements. Test the niobium sample for the presence of niobium oxide compounds. Heat the niobium, and see if the level of radioactivity in the lab increases. Place the niobium under pressure, and see if the level of radioactivity in the lab increases.

its fine can u point me to someone who can help plz
ok one sec
thx
i need some one to help me who is good at phisics
Niobium does exists as different isotopes, so, in order to verify the radioactivity from a given sample of niobium, we have to search for radioactive isotopes inside that sample first
ok thx verry much
