Dosimetric Studies on Some Chemical Materials and Its Possible Use as Radiation Monitors

Abstract

Dyed solid materials (thin films- gels), dyed solutions dosimeters and natural compounds (EPR dosimeters) have wide-spread applications in radiation processing for installation, process qualification and routine dose control for both gamma rays and electron beam irradiation. The introduction of new types of dosimeters is due to the effort of seeking for more reliable, more stable, simpler and cheaper systems as routine dosimeters and/or label dosimeters. The main objective of this work is to study the possibility of preparing some chemical materials (dyed films- dyed gels- coloured soluble complexes-dyed solutions –natural compound), and study the dosimetric properties for the prepared materials. The results obtained in this work can be summarized in the following: Chapter 1 This chapter includes two sections: Section 1: introduction about Gamma and Electron Beam Radiation Processing and Some typical radiation processing applications and Industrial irradiators for radiation processing and Radiation Dosimetry and EPR – Applications. Section 2: literature survey about interested work, film dosimetry, EPR dosimeters, complexes of Chromium, Gel dosimeters and liquid dosimeters. Chapter 2 Deals with the reagents and chemical used information and the experimental part including the preparation of the different dosimetry systems and the experimental techniques used for irradiation and measurements. And practical method used to do this work. Chapter 3 This chapter includes results and discussion related of the irradiation of the prepared dosimeters and divided into four sections:
