“…Отметим, что значения удельных активностей радиону-клидов, указанные в Приложении 3 к ОСПОРБ 99/2010, со-ответствуют значению годовой граничной дозы 10 мкЗв/ год или уровню пожизненного риска около 10 -6 . Данные литературы [2,4,5,7] показывают, что наибо-лее часто остаточное радиоактивное загрязнение почвы связано со следующими радионуклидами: H-3, C-14, Cs-137, Co-60, Sr-90, Ra-226, изотопами урана и трансурано-выми элементами. При этом такие мобильные элементы, как углерод и стронций, встречаются как в почве, так и в воде, а очень мобильный тритий -преимущественно в воде.…”

Выбирались радионуклиды или цепочки радио-нуклидов с периодом полураспада материнского ра-дионуклида, как правило, более 5 лет.…”

“…В рамках реализации ФЦП ЯРБ-2 предусмотрена разработка и обоснование радиационно-гигиенических требований к реабилитации объектов и территорий, подвергшихся радиоактивному загрязнению в результате прошлой деятельности», в виде одних санитарных правил и трех методических указаний. В предыдущих публикациях нами представлены предложения по выбору радиационно-гигиенических критериев безопасности дезактивированных участков территории, зданий и сооружений; обоснования методологических и методических подходов к обследованию реабилитированных участков территорий; оценке доз облучения населения, проживающего в зоне влияния объектов ядерного и радиационного наследия [8][9][10][11][12][13]. Радиационно-гигиенические критерии безопасности дезактивированных участков территории, зданий и сооружений одобрены Российской научной комиссией по радиологической защите (РНКРЗ), на заседаниях которой данный вопрос обсуждался дважды [14,15].…”

For the provision of the radiation safety of the public during the termination of the nuclear and radiation legacy within the boundaries of the Federal Targeted Program “Provision of the nuclear and radiation safety for 2016-2020 and up to 2030”, the following documents were developed: draft of the sanitary rules “Hygienic requirements for the remediation of the facilities and territories contaminated by man-made and natural radionuclides due to the past activities of the facilities of nuclear and non-nuclear branches of industry” and three methodical guidelines on the survey of the remediated territories, buildings and structures and assessment of the doses of the public residing in the zone of influence of the nuclear legacy facilities. The sanitary rules were based on the directions of the future use of the remediated territories, buildings and structures as well as on the radiation-hygienic safety criteria. It was assumed that dose criteria for the public considering the quota (0.3 mSv/year) is applied for remediated sites of the nuclear facilities (radiation facilities). The remediation of the radioactively contaminated areas with the residing public is based on the requirements of the Federal Law № 1244-1, 15.05.1991 “On the social protection of the citizens exposed due to the Chernobyl NPP accident”. Originally the drafts of documents were developed considering the approval in 2019 of the new Norms of the Radiation Safety – 2019, harmonized with the international recommendations and standards. Due to prolongation of the existing Norms of the Radiation Safety 99//2009 for the extra five years, the drafts of the regulations are adapted to the existing NRB 99/2009 and OSPORB 99/2010.

The article provides data on the radiation situation on the research of the year 2018 territory adjacent to the site of the peaceful nuclear explosion “Globus-1” after carrying out rehabilitation works (2014-2015), made with the purpose of removal accidental contamination. We analyzed the dynamics of radiation situation during the period from 2008 to 2018 year and assessed the effectiveness of rehabilitation works on basic indicators: the values of the dose of technogenic radionuclides content in soil, water and other objects the environment. According to the results of comparing the number of measurements exceeding the dose rate of 50 nSv/h (background value for outside contamination 2014 years) in samples of 2014 and 2018 years found that 80% of exceedances, enshrined in the year 2014, percentage of exceedances in 2018 year amounted to only 3%. Another performance indicator associated with the feature to the rehabilitation of this object. A large number of low level activity in soil was inappropriate to remove the burial and the decision to use the ground as a lower layer of reclamation was justified. Research has shown that in the spectral composition of gamma background rehabilitated territory intensity peaks of caesium-137 is many times greater than background levels. In selected soil samples recorded elevated levels of cesium-137 (up to 32500 Bq/kg on wet weight), and collected on such soil samples of herbs have elevated concentrations of cesium-137 (up to 2000 Bq/kg) and strontium-90 (up to 400 Bq/kg)on the dry weight basis. All elevated levels of activity concentration of cesium-137 were found in local areas, within the path of radioactive contamination, selected in year 2014. After carrying out rehabilitation work there has been a significant decrease in the levels of external radiation man-made radionuclides and on formal grounds completed rehabilitation work provided the requirement of Russian Safety Norms 2.6.1. 2819-10 and radiation dose does not exceed 0.3 mSv/year, however, high dose rate recorded in separate locations on the recultivated territories indicate incomplete and insufficient as completed rehabilitation.
