AbstractAbstract
[en] Seasonal variations of lead concentration in roadside soils and plants in 12 sites in Damascus city have been investigated. Lead concentrations in soil were found to be varied from 78.4 ppm to 832 ppm; lower levels in the wet period than in the dry period were observed. While lead levels in roadside plants varied between 3.39 ppm to 13.28 ppm. The results have also shown that most of the vegetables grown on the roadside of Damascus city have high concentrations of lead and the normal washing does not decrease it to unacceptable level.

AbstractAbstract
[en] The aims of this project were to develop a method to measure the amount of 59Ni in stainless steel and to determine the detection limit for this method. 59Ni is produced by neutron activation in the construction material close to the core in a nuclear reactor and it is important to know the amount of 59Ni present as it governs the classification of the waste. If the amount of 59Ni is known at different locations in relation to the core, it is also possible to refine the calculation models of the neutron flux in the reactor. Accelerator mass spectrometry, an ultra-sensitive method for measuring small concentrations of radionuclides as well as stable nuclides, has been used in this investigation to determine the concentration of 59Ni (and thereby the activity) in stainless steel. As the cobalt content in stainless steel is the main contributor to the background in a measurement of 59Ni, a method for the chemical extraction of nickel from stainless steel, including a purification step to reduce the cobalt content in the sample, has been developed. The detection limit for 59Ni has been determined to 100±30 Bq per gram nickel (100±30 Bq/g) with the present status of the system
