Medical dosimetry with alanine

Research and development are carried out within the field of medical reference dosimetry using EPR (electron spin ressonance) of alanine. The current research focusses on applications in external beam radiotherapy (MV photons with or without strong magnetic fields). Applications include dosimetry in the context of animal irradiations.  

Three alanine pellets are placed in a special water-tight holder as shown below.
