| Research Abstract |
Various foods including farm products, fishes and dairy products collected in the contaminated areas in Bangladesh and Mongolia have been analyzed. As a result, it becomes possible to evaluate the actual condition of contamination, to presume the pathways of exposure and to estimate total intakes of toxic elements for the people considering their eating habits. Also, a two-detector measurement system, consisting of two Si(Li) detectors with a vacuum cap and an X-ray absorbers, has been established in in-air PIXE system, and the method of quantitative analysis has been developed. Furthermore, the new method of quantitative analysis of living plants has been developed, and it became possible to observe movement of certain toxic elements in living plants.
