Radioactive trace elements, which would be in micrograms, are difficult to trace even with sensitive instruments," Dr. Lochab said. "Our body also contains trace elements in radioactive form but those elements cannot be detected with any external instrument. Even if we assume Radioactive ink in the new currency notes is used as a trace element, it's impossible to detect it with sensor or any other external instrument," the nuclear scientist said.
