Imaging Plate Technology Used in Measurement of Irradiation Tracks

The imaging plat (IP) responsivity to irradiation tracks was theoretically studied in the present work. The results show that the IP responsivity to different irradiation tracks has the following relationship: α track＞β track＞γ track. The theoretical calculation is experimentally proved to be reliable. The possibility to measure only one kind of tracks in a mixed irradiation field (α, βand γ-ray), interference of one to another and shielding method were explored. The IP technology used in the field of phytoremediation of radionuclide contaminated soil was introduced.
