Investigation of Radiation Damage in the Monazite-Type Solid Solution La_1-xCe_xPO₄.

ABSTRACT: Crystalline materials such as monazite have been considered for the storage of radionuclides due to their favorable radiation stability. Understanding their structural chemical response to radiation damage as solid solutions is a key component of determining their suitability for radionuclide immobilization. Herein, high-resolution structural studies were performed on ceramics of the monazite solid solution La_1-xCe_xPO₄ (x = 0.25, 0.5, 0.75, 1) in order to understand the role of structural chemistry on irradiation stability. Ceramic samples were irradiated with 14 MeV Au ions with 10¹⁴ ions/cm² and 10¹⁵ ions/cm² to simulate the recoil of daughter nuclei from the alpha decay of actinide radionuc
