The Characteristics of Spatial Distribution of the Radionuclides Pu in Soils and Lake Sediments in China
Bibliographic record
Abstract
Nowadays,environmental pollution is one of the most serious problems and radionuclide pollutions are particularly serious in environment.According to sources,activity and spatial distribution of radionuclides Pu,summary and review were made by previous study in different environment mediums,such as soils and lake sediments.It is vital difference for the changes of the activity of 240 + 239Pu in surface soils from different areas of China,but typically less than 1mBq/g.Pu inventories are less than 60Bq/m2 in soils,it was demonstrated that no influence from Chinese Nuclear Test Site has occurred to these areas,but from global fallout.Pu inventories and 240Pu/239Pu atom ratios are both similar with global fallout.There were significant differences of the activity of 240 + 239Pu in lake sediments and 240Pu/239 Pu atom ratios are also similar with global fallout.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
