Popis: The article briefly describes the procedure of reconstruction of integral iodine-131 fallouts using fragmentary data on iodine-131 fallouts in May-June 1986, as well as results of determination (in the late period after the accident) of iodine-129 concentration in the soil and values of integral fallouts of cesium-137 in the settlements of the Bryansk region of Russia. Results of estimation of integral iodine-131 fallouts (in the area of 32 soil sampling points) are presented in the table form. Regularities of ratio (131I/137Cs)II change in the integral radionuclide fallouts are being determined and values of integral iodine-131 fallouts are being estimatedfor the other settlements of the region with the known values of integral cesium-137 fallouts. It is shown that variability of the average for settlements values of integral iodine-131 fallouts is 70 times less then variability of corresponding integral cesium-137 fallouts.
