Description
The Radiation Sterilization Plant operated at the Institute of Nuclear Chemistry and Technology (INCT) is using the dosimetry method based on optical signal measurement at polyvinylchloride (PVC) film which is 30 years old. After so long storage time, a scrupulous revalidation of the method is necessary. In the report there were presented results of investigations dealing with physical parameters mainly. It was ascertained that PVC film used in the INCT belongs to different batches. Thickness scattering is low (±2%), but the transparency, sensitivity to radiation, repeatability of dosimetric signal and other parameters are changing to a wide extent. As a result, each scroll of the PVC film must be carefully checked and calibrated before its dosimetric use. (authors)

Dzialajaca w Instytucie Chemii i Techniki Jadrowej (IChTJ) Stacja Sterylizacji Radiacyjnej wykorzystuje metode dozymetryczna oparta na pomiarze sygnalu optycznego generowanego w folii z polichlorku winylu (PCW) zakupionej 30 lat temu. Tak dlugi okres przechowywania folii jest czynnikiem, ktory zmusza do starannej rewalidacji metody. W raporcie przedstawiono wyniki badan dotyczacych przede wszystkim parametrow fizycznych. Stwierdzono, ze posiadana przez Instytut folia PCW pochodzi z roznych transzy. Rozrzuty grubosci sa niewielkie (±2%), natomiast przezroczystosc, wrazliwosc na promieniowanie, powtarzalnosc sygnalu dozymetrycznego i inne parametry zmieniaja sie znacznie. W rezultacie kazdy krazek folii musi byc starannie sprawdzony i skalibrowany przed jego dozymetrycznym wykorzystaniem. (autorzy)Additional details
