Preliminary results of investigation of some sugars (maltose, saccharose, commercial sugar) as sensor
materials for a high dose dosimetry of ionizing radiation are presented.
An advantage of using sugars consists in fact that ionizing radiation creates in them two kind of signals:
colour centra (spectrophotometric read-out) and paramagnetc centra (read-out by EPR method). This allows
to choose more convenient – in particular conditions – a method of analysis and more exactly to estimate
uncertainties connected with analytical procedures.
The results indicate saccharose as better than others dosimetric material with a treshold at ~100 Gy
for the EPR method and ~5 kGy for the optical one.
The investigation reveals a high discrepancy of physicochemical parameters and generally a low quality
of Polish grocery sugar.
