Ultra-high intensity lasers in use are connected with ionizing radiation sources that raise a real concern in relation to installations, personnel, population and environment protection. The shielding of target areas in these facilities has to be evaluated from the conceptual stage of the building design. The sizing of the protective concrete walls was determined using computer codes such as Fluka. For the experiments to be carried out in the facility

The fading of the thermoluminescent phosphors used as dosemeters is of great importance when it comes to calibrating a dosimetric system. The present paper presents the results of a series of experiments performed in order to determine some fading characteristics of TLD-100 (Harshaw Chemical Co.). The experiment was performed using two batches of dosemeters that were irradiated with X rays simultaneously and with the same dose. One of the two batches
