The present work presents the status of the development of synthetic diamond devices suitable for dosimetric applications. The extraordinary characteristics of chemically vapor deposited (CVD) diamond such as tissue equivalence, radiation hardness, and lack of solubility in water and sanitizing agents, makes CVD diamond a very promising material for dosimetric applications. Recent investigations have shown that CVD techniques allowed the growing of good quality diamond films in a diversity of substrates to be used in the form of ionization chambers, thermoluminescence (TL) and optically stimulated luminescence (OSL) detectors and dosimeters. Successful results have been obtained related to gamma, beta, X-rays and UV radiation. In spite of the significant results, some problems remain dealing with dose behavior and linearity, dose rate dependence and stability. Therefore, a lot of research work is necessary to improve the synthetic material characteristics to optimize the radiation dosimeter device performances.
