Title: Nuclear physics and method of microanalysis of elements

Lecturer :Doan thu Phong

Objective : Use of portable radioactive sources for themicroanalysis of elements ( small budget ); use of simple detectors at normal temperature . Perspective : creation of a microanalysis center.

Subjects :

1.  - Reminders of some notions of nuclear physics necessary for the microanalysis
    - nuclear reactions
    -   Elactic sacattering, Rutherford scattering
    - beta+ and beta- decay
   
- electron capture
    - radioactivity alpha

2. - Interaction radiation-matter

    - energy loss
    - reminder of X-ray emission mechanism
    - X-ray in radioactive decay

3. - Radioactive sources

    - of neutrons, alpha, X and gamma rays
    - Use of portable radioactive sources for the microanalysis of elements

4. - Back scattering

    - analysis by the method of back scattering

5. - Activation method . Radiative capture ( proton, gamma ), ( neutron, gamma )

6. - XRF ( X ray fluorescence )

    - method Pixe ( particle induced X-ray emission )
    - experimental setup

Domain of applications :

    - medecine : biomedical sample
    - alimentation
    - environment :pollution
    - geology , archeology
    - electronic components
    - production : ( metellurgy, cimentary, petrolium ...)
    - art : painting

In connection with this program, one may associate other subjects such as : logic of application, data treatment
