The object of research is radiation doses to residents of reference settlements (S) of radioactively contaminated territories (RCT) due to contamination of these territories as a result of the Chornobyl Nuclear Power Plant (ChNPP) accident. The purpose of the work is to determine the main radiation and hygienic factors of the formation of radiation doses to the population of RCT of the Kyiv region in 2022-2024 and to study their dynamics on the basis of our own experimental studies in the reference S in 2010-2024. Research methods - dosimetric, radiochemical, mathematical, statistical. The comprehensive radiation and hygienic monitoring carried out in 2022 in 8 RCT settlements of the Kyiv region showed that the annual effective doses to the population in the surveyed settlements at the current stage of the accident are formed due to internal doses that do not exceed 0.05 mSv year-1 in Ivankivska OTC and 0.20 mSv ∙ year-1 in Poliska OTC with the RCT criterion of 1 mSv year-1. A 1.7-fold decrease in annual internal doses was registered in the surveyed Polissia OTC (0.030 mSv year-1 in 2019 and 0.018 mSv year-1 in 2022), in Ivankiv OTC (1.1-fold) (0.018 mSv year-1 in 2016 and 0.016 mSv year-1 in 2019). It was established that the main factor that forms the internal exposure dose of the residents of the surveyed communities of the Kyiv region is the intake of 137Cs in the body with forest products, the content of 137Cs in which, as in previous years, significantly exceeds the permissible level (dried mushrooms by 80 times, dried berries by 12 times). The content of 137Cs in milk and potatoes is much lower than the permissible level and the consumption of these food products cannot significantly affect the formation of internal dose. The values of annual effective doses of external exposure to the population in the surveyed S are 269-317 μSv - year-1, which is slightly higher than in previous studies in 2019 (242-307 μSv - year-1), mainly due to the Polissia S.

Saving a scientific data set occurs in two stages:
1.) Creating a data set
Enter the name of the set, a brief description of the set (annotation), and click the “Create set” button. After that, a draft data set will be automatically created, which you can save for further work with the set. The system will redirect you to the “Data set information” page.
2.) Filling in the data
On the “Data set information” page, you need to fill in all the fields related to the data set and upload the files.
Please note! Each file is uploaded separately. This is done to ensure the stable operation of the system.
Once you have filled in the information about the scientific data set and added the necessary files, you can save the draft or send the data to the system.
Please note! Once the data has been sent, you cannot change it.
Drafts are necessary for storing the data set and editing it before sending.
All accounts on the NRA website go through a standard registration procedure and are verified. However, in order to obtain additional features, such as publishing open reviews of academic texts, verification by affiliation is required.
To obtain the status “verified”, you must change your primary email address to a corporate one, which is tied to a scientific or educational institution.
For example: user@ukrintei.ua, user@nas.gov.ua
After confirming your corporate email address, your account will be automatically verified by affiliation.
If your email address is corporate, but your account does not have a verification mark, you need to write to us at the email address NRAT@ukrintei.ua. After verification, we will add your address to the database, and your account will be verified.
After completing the verification procedure for affiliation, you can change the primary email address to a convenient one for you, without losing your status during the current verification.
You only need to verify for affiliation once.
* We use corporate addresses from the Unified State Database on Education and the State Register of Scientific Institutions Supported by the State
To search for news published on the official website of NRАT in the “News” section, you need to enter one word, several words, or an exact phrase in the search field. Different terms are separated by spaces.
The search is performed everywhere – in the title and the news text.
For a more comprehensive result, it is recommended to use word stems (parts of words without endings).
When using multiple words for the search, they are combined using one of the logical methods described below.
By default, the logical connector “and” is used. In this case, search results will include all news releases that contain the specified words, even if they are located separately from each other and are in different parts of the text.
Example: Search phrase: OECD report. Search result: all news containing the words “report” and “OECD” in the text and in the title, both together and separately.
If a phrase or phrase is enclosed in quotation marks (“), the results will include all publications where this exact phrase or phrase is found.
Example: Search phrase: “OECD report.” Search result: all news containing the exact phrase “OECD report.”
If you know the publication date of the news or are interested in a specific time frame in which they were published on the website, you can select such a date or date range in the additional field that looks like a calendar. The date is entered in the format year-month-day and confirmed by clicking on the corresponding date in the calendar dropdown. You can enter a date or choose one by browsing through the calendar by months and years. By default, the interval starts from the oldest date (2018-01-23) and ends with the current date.
You can also use one or more hashtags, which are located under the search field on the right side of the “News” page.
Please note: The search for academic texts is carried out in a separate search window at the following link https://nrat.ukrintei.ua/searchdb.
