“…Aswan granitic rocks occupy a region in southern Egypt and cover the central part of the area near Aswan city within latitudes 24 • 5 , 18 • 5 N and longitudes 32 • 53 , 26 • 07 E. Aswan granite was the third most important stone used in the Egyptian civilization, following sandstone and limestone. It was used for vases, statues, sarcophagi, and buildings, commencing from at least the Early Dynastic Period [10].…”

The present study was carried out on commercial types of Aswan granite used as building and decorative materials. Nearly 29 granitic rocks samples from 11 classes (black Aswan, red Aswan, dark Rosa, light Rosa, yellow Verdi, grey Shirka, Gandolla, Forsan, red Nefertiti, Royal, and white Halayeb) were collected from three stations near Aswan city for petrographical description and assessment of natural radioactivity. The petrographical study of granites was conducted by polarized-light microscope in order to determine their mineralogical composition and investigate their texture; the activity of the natural radionuclides 238U, Ra226, 232Th, and 40K was measured by gamma-ray spectrometry with a NaI(Tl) detector. The average values of the activities, 52.2 Bq kg−1, 57.8 Bq kg−1, 31.2 Bq kg−1, and 1055.7 Bq kg−1 of U-238, Th-232, Ra-226, and K-40, respectively, were higher than that the world average values of 35 Bq kg−1, 30 Bq kg−1 and 400 Bq kg−1 for 226Ra, 232Th, and 40K, respectively, according to the recommended levels from UNSCEAR reports. The minimum and maximum values obtained were compared with the value ranges from other locations in the Eastern Desert, highlighting the fact that that the maximum values obtained in this work are higher than those in other areas. According to the radiological hazards indices results, most samples lie in the permissible level ranges, suggesting their favorability for use as building materials. In contrast to that, some samples have some environmental parameters higher than the international levels, indicating their unsuitability as building materials.

A set of Roman glass fragments, excavated at Bliesbruck–Reinheim (French–German border), were analysed by electron probe microanalysis (EPMA) and micro‐synchrotron radiation‐induced x‐ray fluorescence (µ‐SRXRF) in order to determine the major, minor and trace chemical composition. Based on this analysis, five classes of mono‐coloured glass could be discerned. However, one piece of this set was not mono‐coloured, but consisted of a mixture of brown and white opaque glass. This fragment was investigated using EPMA and transmission electron microscopy (TEM) in order to gain a better insight into its microstructure. Both colours proved to contain small crystalline inhomogeneities. Structural information reveals the form in which the detected elements are present and helps to explain the appearance (e.g. colour) of the material. Copyright © 2004 John Wiley & Sons, Ltd.
