Abstract
Total uranium content was determined in soil and plant samples obtained from various areas in the Nile Delta. Samples taken from east and west of the delta, Suez canal cities and from the Alexandria region were analyzed using laser fluorimetry (LF). Uranium was extracted from digested samples with methyl-isobutyl ketone and measured using a laser fluorimeter. The radium content of the same soil samples was determined using gamma spectroscopy. The uranium content of plant samples was determined using LF, since this technique has a detection limit lower than that of GS. Uranium content in the samples varied between 0.6–4.4 μg/g for soil and 0.032–0.17 μg/g for plant tissue.
