@milos
A Gradiometer is just a Meter which measures gradients between whatever...
If you mean a gradiometer made of magnetometers:
It measures the difference of the magnetic field vector between two measuring points. Means, whatever is magnetized, changes the magnetic flux and can be detected. Try to pick up your golden nuggets and your silver coins by a magnet, you can continue with copper, plumbum, aluminium, tantal, wismut or brass with more or less no result. But yes, there are non-metalic alloys which are magnetic, but not to find on roman sites. Bronze, pur is not magnetic, but can be magnetic in an alloy, esp. if longer laying in the ground.
A roman tomb mainly means carbonized bones in a pot, maybe some nails and fibulas . The main thing you might detect with a gradiometer will be the pot itself.
