(26) Czy można oszukać Spektrometr rentgenowski?

Those who have never seen something have the most to say... A common myth is that an X-ray spectrometer cannot detect gold-plated counterfeits, coins, or gold-plated jewelry. This is false. The only type of counterfeit that such a device cannot detect is a bar/coin with a tungsten insert. But there are other methods, such as measuring the velocity of metals or analyzing the sound produced by the coin. Does your gold dealer have a spectrometer and use it daily?
