Abstract
The article summarizes information on the accumulation of plutonium by plants. The factors influencing the process of plutonium migration in the «soil-plant» system are considered. A review is given of plutonium transfer factors by plants as quantitative indicators of migration. It is shown that the plutonium transfer factors by plants are very variable and cover six orders of magnitude. It is noted that for a territory subject to global fallout, the transfer factors of plutonium are significantly lower than for a polluted one. For this, special publications of the IAEA, publications on the study of the accumulation of plutonium for background territories and territories subject to radioactive contamination, were considered. The data on the influx of plutonium into various agricultural crops grown at the Semipalatinsk test site are given. Transfer factors of plutonium by agricultural crops are in the range n × 10–5–n × 10–1 for the territory of the Semipalatinsk test site. Literature data on the accumulation of plutonium by wild vegetation growing in the Chernobyl fallout territory, etc. are considered. Transfer factors of plutonium by herbaceous vegetation for the territory of Chernobyl fallout are at the level of n × 10–2. The article summarizes and presents information on the plutonium transfer factors by various plants organs. In general, based on the analysis of literature data, the plutonium transfer factors are in the range n × 10–7–n × 10–1.
