Radiochromic sensors, which enable express visualization of ionizing radiation by change in color or transparency, are ubiquitous in medical, scientific, and industrial applications. Most of the currently known radiochromic materials belong to organic compounds, while the potential of inorganic materials in terms of radiochromicity remains nearly unexplored. Here we report the measurements of dose sensitivity of radiochromic coloration intensity and decay kinetics of radiation-induced color centers for inorganic Ba-Sr fluoride borates with the compositions Ba7(BO3)3.5F3.5 and Ba3Sr4(BO3)4F2. Experiments with irradiation of these polycrystalline materials using broadband synchrotron radiation (5–17 keV) revealed that the Ba3Sr4(BO3)4F2 material has dose sensitivity of radiochromic coloration potentially suitable for measurements of doses from several cGy to ∼10 Gy air kerma. The Ba7(BO3)3.5F3.5 material demonstrated a slightly lower dose sensitivity of radiochromic coloration than Ba3Sr4(BO3)4F2, but also revealed the possibility of quick bleaching of the radiochromic coloration using intense visible light, which may be used in the development of reusable radiochromic sensors.
