摘要

基于多年的监测观察，确定了切尔诺贝利事故后30年间苏格兰松(Pinus sylvestris L.)地上生物量主要组织和器官对137Сs的吸收动态及其放射性污染的特性。采用了经验(观察)、放射生态学和统计学方法。结果表明:1991 ~ 2002年木材的传递因子值呈上升趋势，到2020年呈单调下降趋势;内部树皮、1年嫩枝、2年嫩枝、1年针叶、2年针叶、细枝粗枝和细枝粗枝的多年动态相似，转移因子在1991 ~ 2002年呈增加趋势，到2020年呈下降趋势。在1991 ~ 2020年的整个观测期内，地表传递因子的值呈单调下降趋势。

Dynamics of 137Сs content in tissues and organs of scots pine (Pinus sylvestris L.) in moist fairly infertile pine type of Polissya of Ukraine after Chornobyl accident

Based on multiyear monitoring observations, dynamics of 137Сs intake into the main tissues and organs of aboveground phytomass of Scots pine (Pinus sylvestris L.) during 30 years from the Chornobyl accident was determined as well peculiarities of their radioactive contamination. Empirical (observations), radioecological and statistical methods were used. It was found that for the wood increase of values of transfer factor was observed between 1991 and 2002 yrs with the further monotonous decrease of this value up to 2020; in internal bark, 1-year shoots, 2-year shoots, 1-year needles, 2-year needles, twigs thick and twigs thin multiyear dynamics was similar – an increase of values of transfer factor in the period of 1991 - 2002 yrs with further decrease of it up to 2020. At external bark, monotonous decrease of values of transfer factor was found during the whole observation period 1991 - 2020.
