influence of different soil's parameters on the penetration of 137cs

in this work, 137cs activity concentration of soil in five depths and in six meteorology stations in terms of bq/kg has been measured. for each thirty soil's samples, parameters such as kind of soil, density and hydraulic coefficient of transmission were determined. correlation coefficient between 137cs activity concentration and raining average, hydraulic coefficient of transmission and soil's density was calculated. results for 5,15,30,45 and 60 cm depths were obtained as 0.89, 0.99, 0.98, 0.70 and 0.66, respectively. finally, correction coefficients for some locations with acute gradients were determined.
