AbstractAbstract
[en] The porosity and microfracturing samples from the disturbed zone of full-scale experimental deposition holes in the TVO Research Tunnel were investigated with the 14CPMMA method on gneissic tonalite at the Olkiluoto site in Eurajoki in Finland. The method involved impregnation of the rocks with 14C methylmethacrylate, irradiation polymerization, autoradiography and optical densitometry with digital image processing techniques. Scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDX) were used to investigate in greater detail the pore apertures and minerals in porous regions. SEM/EDX measurements were conducted on 14CMMA-impregnated samples. (6 refs., 99 figs., 2 tabs.)
