Updating of currently used techniques for reconstruction of internal radiation doses to the thyroid and a whole body in residents of the Russian Federation inhabitants, exposed to radioactive fallout following the Chernobyl accident in 1986 Part 4. Updating technique for standardization of thyroid and a whole body internal radiation doses got by residents of settlements the Russian Federation contaminated with radionuclides in the first year after the Chernobyl accident
New approach to calculation of modified standard internal doses to thyroid and a whole body of residents of contaminated settlements based on radiometry data of 1986 is presented. The approach was used for calculation of modified standard doses for all residents added to the joint data base of the NRER and the Institute of Radiation Hygiene of St.-Petersburg. Power regressions of averaged standard doses with regard to a settlement and density of contamination with <sup>137</sup>Cs were practically affected neither by a region of residence nor a settlement type. Compound error of calculation of standard doses by regression dependence is 1.6-1.7. Compound error of calculation of standard doses with regard to a settlement is 2.0-2.3.
