Database of meteorological and radiation measurements made in Belarus during the first three months following the Chernobyl accident

Results of all available meteorological and radiation measurements that were performed in Belarus during the first three months after the Chernobyl accident were collected from various sources and incorporated into a single database. Meteorological information such as precipitation, wind speed and direction, and temperature in localities were obtained from meteorological station facilities. Radiation measurements include gamma-exposure rate in air, daily fallout, concentration of different radionuclides in soil, grass, cow's milk and water as well as total beta-activity in cow's milk. Considerable efforts were made to evaluate the reliability of the measurements that were collected. The electronic database can be searched according to type of measurement, date, and location. The main purpose of the database is to provide reliable data that can be used in the reconstruction of thyroid doses resulting from the Chernobyl accident.

► Meteorological and radiation measurements done after the Chernobyl accident in Belarus were collected.
► Data were verified and incorporated into a single database.
► Results of this study is being used to improve the thyroid dose estimates after the Chernobyl accident.
