The results for the ICP-MS determination of "Tc in soil were compared with those for 137Cs [39]. The "Tc/137Cs ratio in soil was 3.9xlO-3 to 3.8 x 10 2 which is considerably larger than that expected theoretically. [Pg.30]

Various ancillary measurements from accompanying cores were needed to calculate accumulation rates and describe phase associations of Hg. 21wPb and 137Cs profiles in sediments were used to determine sedimentation rates from which historical interpretations could be made. [Pg.428]

The lower size limit of crystalline population is 0.31 /. This is based on experimental determination that 137Cs atoms/Mg = 2400 X 109 for fractions consisting of all particles less than 1.2/ in diameter. This value coupled with the equation 137Cs/Mg = 1170 X 109/

From the data of Table 3.7 and the mineral composition of the rocks (Tables 3.4 and 3.6), the distribution coefficients of the minerals (kcfi)) can be determined by Equation 3.9. The distribution coefficients for the different groups of minerals and the calculated relative sorbed quantity of 137Cs ion (x., and the differences between the experimental and calculated values (AxCs) are shown in Tables 3.7 and 3.8. [Pg.185]

As seen in Table 3.7, the differences between the experimental and calculated values (<0.07) are within the deviation of the determination of the mineral composition and relative sorbed quantities of 137Cs ion (5%-10% ). So, the linear model fairly well describes the relation between the mineral composition and sorbed quantity of cesium ions on different rocks. [Pg.185]
