Dosimetry Gamma

Dosimetry is the measurement of the absorbed dose calculated with the help of dosimeters.
Correct understanding and utilisation of this technique are essential for validation, commissioning tests and control of this process.

The dosimetric system includes:

  • Red Perspex" or "FWT 60" type dosimeters,

  • a spectrophotometer to measure the optical density of the dosimeter being processed,

  • a micrometer to measure the thickness of the dosimeter being processed.

  • Calibration of each batch of routine dosimeters is done in accordance with international standards.
    The period of validity of the calibration is indicated, and justified.
    The same instruments are used to draw up calibration curves and routine dosimeters.
