Explosive decomposition of heavily irradiated NaCl
In heavily irradiated NaCl explosions can be initiated during irradiation or later, after the irradiation, when the samples are heated to temperatures in the range 100-250 degrees C. As a result of the irradiation Na and Cl-2 precipitates, dislocations and voids are produced, along with stored energy (the maximum value observed until now similar to 76 kJ/mol, which is about 18.5% of the enthalpy of formation of NaCl, 411.2 kJ/mol). This implies that heavily irradiated NaCl is a highly energetic material. We have observed that the samples, which revealed large radiation-induced voids, explode rather easily. In these samples the instability connected with large voids (hot spots) probably initiates the explosive release of stored energy, which is in many cases accompanied by characteristic (explosive) sounds. In this paper we will discuss the nature of the explosions and show that a basically stable insulating compound, such as NaCl, may become unstable after heavy irradiation.
