Effect of the Concentration of Depleted Uranium in Soil on Its Uptake by Tomato Plant
Bibliographic record
Abstract
Depleted Uranium (dU) is usually used in the weapon to increase its destruction power inflected to the target. Therefore, this study was conducted to detrmine the effect of of a range of dU concentration in the soil an incident of the desrruction of military tank in southern part of Iraq on radioisotope content in soil and in tomato plant grown in the area. The dU concentration in the incident spots located in Safwan destrict close to Jabel Sanam, north of Rumala oil field was 4000 mg Kg-1 in the soil. The soil also was found to contain a considerable level of 234Th, 226Ra and 40K. Tomato growth was reduced with the increase of dU concentration compared to those grown in same soil of no dU content. It even has failed to grow in the soil with high level of dU. Tomato plant uptake of 238U as determined by radioactivity of its direct daughter 234Th was found to increase with the increase of dU concentration in soil. The dU concentration higher than 500 mg kg-1 soil was lethal to tomato plant.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
