If the NuArc integrator gives a reliable number that, coupled with the aid of a UV meter, can lead us to a calibrated measurement, then we'd have a much better idea of the energy requirements for exposing carbon tissue.

Or you can expose a Stouffer step wedge and develop it to see how much exposure you are getting. The units, then, become an arbitrary number that you double or halve for every two steps on the wedge that you want to move.
