Dosimetric properties of the Institute of Nuclear Chemistry and Technology (INCT) newly-developed alanine-polymer dosimeter ALANPOL are presented. Low percentage content of the cheap racemate form of alanine (DL-a-alanine) is a characteristic feature of this rod (O=3 mm) dosimeter. An X band EPR spectrometer with a cylindrical cavity is used as analytical instrument. The length of the dosimeter is equal to the microwave cavity length. An amplitude of the first derivative of the microwave absorption curve of irradiated dosimeter is used as dosimetric signal. Dosimetric signal is stable and can be measured many times.
In this work, we present results for dosimeters with 10 and 27% of DL-a-alanine designed to the measurements within the dose range 0.5-100 kGy. ALANPOL dosimeters are water-resistant and non-sensitive for the most of contaminants. They can be used for gamma rays and high energy electron beems and can be stored many years for archieval purposes.
