The radioecological subsystem of the RGMDR - REKOR collects and processes information on the radiation and non-radiation factors that act on the contaminated territories as a result of the Chernobyl NPP accident. In particular, one of the main functions of REKOR is the reconstruction of absorbed doses of external and internal exposure of various groups of the population. The appropriate methodology for the reconstruction of absorbed external doses is described in Section 3 of this issue of the Bulletin. For its implementation, it is necessary to know the radionuclide composition (RNC) of depositions in populated areas from the zone of radioactive contamination. Knowledge of radionuclide composition deposition is also important when assessing absorbed doses of internal exposure of the population. The technique for reconstructing radionuclide composition fallout is described in detail in the previous issue of the Bulletin. Continuing the tradition of publishing a large number of factual data of various kinds related to the implementation of the goals of the Russian National Medical Dosimetry Registry, the tables below contain data on the reconstruction of radionuclide composition fallouts and estimates of absorbed doses for a number of settlements in the Ulyanovsk, Khvastovichsky and Zhizdrinsky districts of the Kaluga region.

Key words
Reconstruaction of absorbed doses, external irradiation, internal irradiation, radionuclide composition, radioactive contamination zone, population, Russian National Medical Dosimetry Registry.
