Detection of the ultimate content of uranium of depleted ammunition in different materials
Keyword(s):
The goal of this work was to determine the ultimate detectable content of uranium arising from depleted uranium ammunition in different natural materials, namely, soil, gravel, wood by ?-spectrometry. The United Nations Environment Programme (UNEP) report has confirmed following findings: (a) it is not possible to detect uranium-containing ammunition by any available instrument in the soil deeper than 40 cm; (b) the scintillation detector MC PHAR, due to its high sensitivity (above 80 keV), is considered to be the ideal detector for low energy ?-irradiation, which is characteristic for depleted uranium.
