SSTC NRS Conducted Radiation Survey of Kyiv-Ivankiv Road Segment after Russian Occupation
On 14 June 2022, SSTC NRS experts conducted radiation survey of the Kyiv-Ivankiv road segment. The radiation survey was conducted along the following route: Kyiv (35-37 V. Stusa St. (SSTC NRS Office) – Academician Palladin Avenue – Velyka Kiltseva Road) – Highway P69 – Highway R02 (Novi Petrivtsi Village – Stari Petrivtsi Village – Lyutizh Village – Demydiv Village – Dymer Village – Katyuzhanka Village – Fenevychi Village – Rudnya-Shpylivska Village – Ivankiv).
The survey was conducted with the help of the RanidSONNI radiological reconnaissance vehicle (mobile radiation survey laboratory) and portable equipment. The gamma radiation survey was supplemented by additional (every 10 km) manual measurements of the ambient equivalent dose rate (EDR) from gamma-ray spectra. Also, additional radiation survey was conducted at the sites used by the russian occupational troops for the weaponry.
No abnormal values were detected during gamma EDR measurement and the results are within the natural background values specific to this area and make 0.04 – 0.10 μSv/h.
15 June, Kyiv-Ivankiv – Dytyatky Checkpoint
On 15 June 2022, SSTC NRS experts conducted radiation survey of the Ivankiv – Dytyatky Checkpoint road segment. The radiation survey was conducted along the following route: Ivankiv – Chornobyl NPP/Dytyatky Checkpoint access road (Sukachi Village – Khocheva Village – Orane Village – Dytyatky Checkpoint) – Sukachi Village (Lenin Street – Shevchenko Street) – Ivankiv (Ivan Proskura Street – Kyivska Street).
The survey was conducted with the help of the RanidSONNI radiological reconnaissance vehicle (mobile radiation survey laboratory) and portable equipment. The gamma radiation survey was conducted along the whole route. The ambient equivalent dose rate (EDR) from gamma-ray spectra was measured for the Ivankiv – Orane Village road segment (every 5 km) and Orane Village – Dytyatky Checkpoint road segment (every 2 km) using portable equipment. Also, additional radiation survey was conducted at the sites used by the russian occupational troops for the weaponry and military assets and personnel. The survey paid special attention to the military equipment left after occupation of these territories.
No abnormal values were detected during gamma EDR measurement of the Ivankiv – Orane Village road segment and the results are within natural background values specific to this area and make 0.10 μSv/year.
Radiological abnormality with EDR of about 6 μSv/h was detected at the roadside during survey of the Orane Village – Dytyatky Checkpoint road segment. The measurement was made at a height of 5 cm from the soil surface. The abnormality was caused by 137Cs isotope. At the same time, EDR made 0.17 μSv/h at a 1 m height, which is within the range of natural background values specific to this area.
No foreign objects were detected during metal detector survey. Hence, it is assumed that contamination was caused by the so-called “hot particle” which could be transferred from the exclusion zone both after the Chornobyl disaster or by means of caterpillar tracks or vehicle wheels of the russian invaders. There are no buildings, places of permanent or temporary residence near the detected contamination site and no agricultural or cattle grazing activities, so the detected radiological abnormality does not pose a threat to human life or health.
The radiation survey is a part of the SURVEY project, intended to identify and reduce the risks of public exposure as a result of contact with radiation sources/radioactive contamination, as well as to reduce public concerns about the anticipated risks associated with the presence of invaders in the exclusion zone.
The experience gained in the course of the project will be used in future during surveys of deoccupied industrial eastern regions.
