Abstract

Using the methods of positron annihilation and optical spectroscopy, the effect of gamma (Co60) and electron irradiation (Cockcroft–Walton accelerator) on NaCl single crystals, followed by annealing at various temperatures. It was found that electron color centers are effective traps of positrons diffusing in the lattice. At the same time, hole centers do not capture positrons. It was shown that positrons are captured by sodium clusters formed in the bulk of NaCl crystals upon annealing (443 K) of irradiated (2650 Mrad) samples. The annihilation characteristics of captured positrons allow us to estimate size of sodium clusters R = 23.0 nm and their concentration Nx = 5.3 × 1017 cm–3. Taking into account the fact that modern optical and positron spectrometers are quite compact and sensitive instruments, the monitoring of the processes of radiation degradation of the geological rock of rock salt can be carried out directly at the disposal sites of radioactive waste rather quickly and with the necessary degree of sensitivity to the accumulation of radiolytic products.

Notes

  1. In further studies, it was shown that upon irradiation of NaCl samples, H and F centers are formed, which aggregate with the formation of chlorine bubbles and nanoscale sodium clusters. Rapidly growing voids bring chlorine bubbles and Na colloids into contact, which can lead to an instantaneous reverse explosive reaction between radiolytic Na and Cl [3–5].
