In this study‚ three different methodologies have been employed for the determination of 226Ra by means of liquid scintillation technique. The first one (referred to as "Rn-LSC-28" hereafter and the tables and figures) is based on the method of Prichard and Gessel (1977) and Cooper et al. (1988) and also used by Escobar et al. (1996)‚ Zouridakis et al. (2002) and Aleissa et al. (2012). In this procedure‚ 8 mL of each standard solution was transferred to a high density polyethylene vial‚ covered with

CHAPTER 1 INTRODUCTION 1.1 Introduction of Research Steel-reinforced concrete is a widely used structural material. The effectiveness of the steel reinforcement depends on the bond between the steel reinforcing bar and the concrete. Reinforced concrete is a composite material in which concrete ’s relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength and ductility. The reinforcement is usually‚ though not necessarily
