In April and August 2015, a massive fire occurred in the Chernobyl Exclusion zone. The fire spread to neighboring areas due to the prevailing strong winds. In this paper, we analyze the peat fires as a unique source of radioactive contamination. After an expedition directly to the peat fire site (the evacuation zone of the Bryansk region), we collected a number of aerosol samples. We came to the conclusion that peat fires cannot be the reason for radioactive particle transport in the Bryansk region as well as in the Chernobyl evacuation zone. During the peat fire, radioactive contamination was not transferred by aerosols beyond 500 m. The 137Cs concentration in the aerosol filters varied between 0.55 and 0.64 Bq/m3, and that at the same distance from the fire seat and peat edge was 4.4∙10-3 Bq/m3; the activity values in the peat bog and in the nearest inhabited locality did not exceed the background values. Strontium-90 was not found in aerosol samples. The soil-to-air transport rate of 137Cs was 2.7∙10-6. After the Chernobyl accident, the majority of the 137Cs was incorporated into the structure of clay minerals, and these did not change during the peat fire. The mobility of 137Cs in the flight peat material particles was established. To confirm the territory status of the evacuation zone, we also collected some food samples. Berries and mushrooms consumed at the assumed rate for dose estimation would result in doses that exceed the public dose limit by approximately a factor of five.

与泥炭燃烧有关的气溶胶活性测量值（布良斯克州的疏散区）。

2015年4月和2015年8月，切尔诺贝利禁区发生了大火。由于盛行强风，大火蔓延至邻近地区。在本文中，我们将泥炭火灾分析为唯一的放射性污染源。在直接考察了泥炭火灾现场（布良斯克地区的疏散区）之后，我们收集了许多气溶胶样品。我们得出的结论是，泥炭大火不能成为Bryansk地区以及切尔诺贝利疏散区放射性粒子运输的原因。在泥炭火灾中，超过500 m的气溶胶不会转移放射性污染物。气溶胶过滤器中的137 Cs浓度在0.55至0.64 Bq / m3之间变化，而距火席和泥炭边缘相同距离的浓度为4.4∙10-3 Bq / m3；泥炭沼泽和最近居住地区的活动值未超过背景值。在气溶胶样品中未发现锶90。137Cs的土壤对空气迁移率为2.7∙10-6。切尔诺贝利事故后，大多数137Cs被掺入粘土矿物的结构中，并且在泥炭火灾中这些元素没有改变。建立了137Cs在飞行泥炭材料颗粒中的迁移率。为了确认疏散区的领土状况，我们还收集了一些食物样本。以假定的剂量估算速率消耗的浆果和蘑菇将导致剂量超出公共剂量极限约五倍。7∙10-6。切尔诺贝利事故发生后，大多数137Cs被掺入粘土矿物结构中，并且在泥炭火灾中这些元素没有改变。建立了137Cs在飞行泥炭材料颗粒中的迁移率。为了确认疏散区的领土状况，我们还收集了一些食物样本。以假定的剂量估算速率消费的浆果和蘑菇将导致剂量超出公共剂量极限约五倍。7∙10-6。切尔诺贝利事故发生后，大多数137Cs被掺入粘土矿物结构中，并且在泥炭火灾中这些元素没有改变。建立了137Cs在飞行泥炭材料颗粒中的迁移率。为了确认疏散区的领土状况，我们还收集了一些食物样本。以假定的剂量估算速率消费的浆果和蘑菇将导致剂量超出公共剂量极限约五倍。
