This method first uses γ-ray irradiation sterilization to improve the anti-washout ability of CPC directly. 
γ-ray irradiation sterilization
Therefore, we propose a method for the preparation of a sodium polyacrylate solution through irradiation polymerization as curing solution for CPC.  It not only avoids the adverse effects of γ-rays on anti-washout agents, but also the CPC blended using this sodium polyacrylate solution had good biological properties and injectability.

A novel anti-washout curing solution of calcium phosphate cement prepared via irradiation polymerization.The anti-washout ability of calcium phosphate cement (CPC) determines its effectiveness in clinical application.  Therefore, we propose a method for the preparation of a sodium polyacrylate solution through irradiation polymerization as curing solution for CPC.
