Abstract:
Yttrium-90 glass microspheres are used in the treatment of liver cancer. Activity calibrations are linked to a series of experiments performed with 90Y solution surrounding non-radioactive microspheres. Through a series of measurements and Monte Carlo simulations, we have tested that experimental model, finding it to be valid. New ionization chamber measurements provide links to earlier work.
