The article contains a description of sacral buildings wall dampness causes. It shows the optimal condition of internal microclimate regarding rooms designed to exhibit historical items. Analysed methods are diagnostic of wall moisture by non-invasive methods. The thermal image examination with the use of microwave electromagnetic radiator was carried out. Two samples of brick were tested; they were exposed to the radiation at total time of 90 seconds. Nominal power of radiator was PN=900W. The author analysed other sources of heat radiation: he changed microwave radiation to infrared radiator, and thus the examination was easier and safer. The results shown in the article are temperatures and infrared radiator test results. The aim is to determine time constant of various radiator work methods. The aim of analysis was to show temperature distribution at given distances from the radiator, which enabled constant temperature distribution at certain stages of running device.
