Using gamma ray transmission for determination of porosity in doped alumina samples

الملخص EN

In this study, gamma ray transmission method have been used to determine the t otal porosity in four samples : pure Alumina (Al2O3), Al2O3 + (0.2wt %) MgO, Al2O3 + (0.6 wt %) Y2O3 and Al2O3.

Wt % (ZrO28).

+ The experimental setup for the gamma ray transmission consist of 13 7Cs gamma source 662 KeV a NaI (T l) scint illation detector measured the at tenuation of strongly collimated gamma beam through alumina samples.

The porosity obtained by the gamma ray transmission method was compared with the measurements by convent ional (Archimedes) method.

It was observed that the porosity measurement by gamma ray transmission method has the advant age of being accurate, nondestructive and fast analysis.
