Recent reports on laser excitation of the low-energy thorium-229 ($$^{229}$$Th) nuclear isomeric state in calcium fluoride single crystals render this system a promising candidate for a solid-state nuclear clock. However, experimental characterization of the microscopic ion arrangement around the doped $$^{229}$$Th and its electronic charge state, crucial for the precise control of the clock transition and assessing the solid-state clock's performance, remains an unresolved task. This study uses X-ray absorption fine structure spectroscopy of $$^{229}$$Th:CaF$$_{2}$$ to investigate the charge state and coordination environment of doped $$^{229}$$Th. The results indicate that $$^{229}$$Th is doped with a 4+ valence at the substitutional site of the Ca$$^{2+}$$ ion, with charge compensated provided by two F$$^{-}$$ ions located at interstitial sites adjacent to $$^{229}$$Th.

There are no clear criteria for standardizing mapping techniques for ambient dose equivalent rate (air dose rate) distributions in different countries. Thus, in this study, manborne, carborne, and airborne radiation surveys were conducted jointly by the Japan Atomic Energy Agency and the French Institute for Radiological Protection and Nuclear Safety in the vicinity of the Fukushima Daiichi Nuclear Power Station to confirm the effectiveness of each organization's monitoring methods. For example, in the manborne survey, the discrepancy between the air dose rates measured by the two institutions was observed depending on whether or not the contribution from radionuclides with different gamma-ray energies was considered when converting the count rates obtained by the detectors to air dose rates. As in this study, comparing mapping techniques among various countries and providing feedback to each other should help to improve the accuracy of zoning scenarios after nuclear accidents.
