The constant rate of supply (CRS) of excess ²¹⁰Pb model was successfully applied to assess ²¹⁰Pb data of two sediment cores from the lake Qattinah, Syria. Gamma spectrometry was used to determine ¹³⁷Cs and ²¹⁰Pb activity concentrations. The bottom of the cores was ²¹⁰Pb-dated to years 1907 and 1893. The accumulation rates were determined using ²¹⁰Pb method and found to vary similarly in both cores from 0.10 ± 0.01 to 3.78 ± 0.57 kg m^-2 y^-1 during the past century. ¹³⁷Cs was used as an independent chronometer. The two distinct peaks observed on the ¹³⁷Cs record of both cores, corre-sponding to 1965 and 1986, have allowed a successful validation of the CRS model.
