Issues of Novaya Zemlia Bay Rehabilitation Due to the Dumping of Radiation-Dangerous Facilities

Abstract

Present-day quantitative radioecology allows for ranking unresolved radiation-related tasks depending on their potential environmental hazard. Successive stages of such assessments are widely known. They comprise estimates of:

• source term activity and radionuclide composition;

• radionuclide release rate from the source term;

• radionuclide transfer and spreading in the environment;

• radionuclide impact on the anthroposphere;

• radionuclide intake by human beings with air, water and food;

• exposure doses with respect to critical population groups;

• comparison of the above doses with admissible levels of radiation impact.
