Uranium contents from bomb craters

Depleted uranium (DU) is a by-product of uranium enrichment process and its use is very dangerous and harmful. We measured uranium concentration in the surface soil (0-5 cm depth) from bomb craters caused by cruise missiles in which DU might have been used as counterweights during NATO attack. Total uranium concentration and isotopic ratio were determined using y-spectrometry and inductively coupled plasma method. Obtained results were in the range 1.7 - 22 mg/kg dry soil that was comparable to the uranium values found in off-side locations of Serbian soils
