Measurements of Uranium radon and radium concentrations by using SSNTDs.
How can we use XRF technique to measure the elements of a cancer samples, taken from ill persons?
To specifically measure the uranium concentration in a sample, you have to use a alpha spectroscopic method that can distinguish the 4.26 MeV alpha decay of U238 from all other daughter product or other nuclides. Unless you already know a-priory that your samples contains mainly U238, SSNTDs will show you tracks from a lot of other isotopes apart from U238. Also, since U238 has such a long T1/2, I think you will have to be very very patient to ever get a track from a U238 decay. it is more promising to try liquid scintilation counting. Here, you can accumulate the alpha decays over a long time, and you should get a good signal for U238.

Dear Dr. Abd,
you can follow the procedure given in attached article for analysis of cancer tissues
