Cultural heritage is exposed to continuous risk of degradation, caused by physical, chemical, and biological agents, aggravated by the environmental conditions. The purpose of this work is to establish the protocol for a new non-disruptive technique of intervention using microwaves for cleaning operations on monumental historical buildings, to eliminate biodeteriogens infesting stones. One step of the proposed protocol concerns measuring the Radon exhalation rate to verify that microwave treatments do not increase the Radon naturally exhalated by building materials. Preliminary results on different types of tuff samples (grey and yellow tuff), typical of the traditional construction heritage are shown.
