Плотность загрязнения территории 137Cs в Беларуси

2016

2046

Ожидается сокращение загрязненной территории к 2016 году в 1.5 раза, а к 2046 году в 2.4 раза по сравнению с 1986 годом

Social protection, medical maintenance and regular health improvement provided to the affected population.

Radiation protection and direct target-oriented implementation of protective measures.

Design and implementation of specific projects to facilitate modernization and efficient utilization of production capacities, natural, primary and labour recourses, social development, human capacity building.

Improvement of public outreach policy on the problems related to mitigation of the Chernobyl accident consequences, including outreach to the population, information sharing and dissemination etc.

В сфере радиационной защиты и адресного применения защитных мероприятий

In the framework of radiation protection and target-

oriented implementation of protective measures

Category 1: Residents of contaminated areas who consume foodstuffs of local production

Reduction of individual effective doses received through the consumption of local contaminated foodstuffs

Category 2: People who live in clean areas, but may consume foodstuffs produced in contaminated areas

Reduction of the collective radiation dose associated with export of foodstuffs produced in contaminated areas

Assess the radiation situation and determine

the levels of ionizing radiation exposure

Exclude production and storage of foodstuffs and raw materials with radionuclide concentration levels

above the specified limits

Evaluate the effectiveness of protective measures, provide their optimal and targeted implementation

Develop a sound strategy of recovery actions
