Within the project “Radon mapping and radon risk assessment in Georgia”, funded by the Shota Rustaveli National Science Foundation of Georgia in 2019‒2022 (SRNSFG FN-19-22022), systematic radon (222Rn, Rn) surveys in indoor air, soil gas, and waters were carried out in Georgia. The indoor radon study included 702 locations in 11 administrative regions of Georgia. Altogether, 1338 rooms in 107 schools, 540 kindergartens, 6 city halls, and 57 homes were examined for radon all year round by exposing solid-state nuclear track detectors RSFV from Radosys Ltd. Rn concentrations ranged from 2 to 1226 Bq m3, with an annual arithmetic mean value of 84 Bq m3 for all the regions. The annual effective doses ranged from 0.2 to 3.8 mSv with an arithmetic mean value of 1.2 mSv a1
