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.

Answer: test the niobium sample to see wheter it now contains other elements.

This is because when an element emits radiation it transforms into another element or elements (the nucleus changes releasing energy and forming nuclei of new elements).
