The equilibrium between the two forms of BCPB indicator is represented as follow in equation 1:
The concentration of acid formed due to irradiation of BCPB /PVA films to a dose D is given by the sum of hydrogen reacting with BCPB-, [H BCPB]D, and the free hydrogen percent in the medium, [H+]D [9] , to maintain the equilibrium given by equation 1, [Total acid formed]D=[HBCPB]D+ [H+]D (2) Where, [HBCPB]D is the concentration of changed BCPB due to the irradiation to a dose D, and [H+]D is the concentration of free acid present in equilibrium after irradiation to a dose D.
cm-3), the concentration of BCPB before irradiation in the films containing 106.
The radiation chemical yield of [H+] in BCPB /PVA films containing chloral hydrate is calculated as follows:
