Aim of the thesis: Development of a new method for determining concentration of the radionuclides in enviromental samples by mean of gamma spectroscopy. Establishing a data set of the soil-plant transfer factor (TF) of radionuclides 238U, 232Th and 40K for some vegetables in Truong Sa island and that of 238U, 232Th, 40K and 137Cs for tea tree from Luong My farm, Hoa Binh province, Vietnam and evaluate the influence of natural radionuclide concentration to the soil-plant transfer process of artificial radionuclide 137Cs.

In this thesis, the author focussed on providing an application framework to be used in brain segmentation - the process of tumor detection. This constitutes setting up software bundled into a Window machine which is easily distributable. Moreover, a segmentation algorithm was implemented and tested using the provided software. In order to test the bundled software by implementing specific brain segmentation from the literature, the author used CT scans freely available from the database of 108 Central Military Hospital.
