英文摘要 | The paper reports on the analysis for the calibration to get an experimental curve which gives the relation between C/C concentration ratio and the ratio of track density on CR-39 to that on LR-115. A group of homogeneous mixtures in different known mixing ratios of monazite and zirconia were prepared. The mixed samples in the form of pellets were irradiated in close contact with small pieces of chemically pre-etched CR-39 detectors on one side and LR-115 on the other side of each test sample. The relation between thorium to uranium concentration ratios C/C versus the ratio of track densities of CR-39 to LR-115 detectors has been obtained as an experimental curve. The obtained experimental curve shows a limited agreement with the calculated curve. A good agreement has been extended until C/C ∼8. Present work was applied on two mixtures of soil and coal fly ash to get the component mixing-ratios in a reasonable accuracy. |
