Resumo
Nowadays, the three dimensional (3D) dosimetry has been studied by many
researchers for application in radiotherapy and radiosurgery treatments, because this kind of
dosimeter enable to evaluate the 3D dose distribution. The alanine gel dosimeter was
developed at IPEN to be applied to 3D dose evaluations using magnetic resonance imaging.
This dosimeter is a gel material based on the transformation of the ferrous ions in ferric ions,
which presents significant improvement on previous alanine systems developed by Costa
(1994). The DL-Alanine (C3H7NO2) is an amino acid tissue equivalent that improves the
production of ferric ions in the solution. The ferric ions concentration can be measured by
spectrophometry technique. This work aims to analyse the stability and influence of the dose
rate in the optical signal response of alanine gel dosimeter, since these two properties are very
important for characterization and standardization of any dosimeter.
