Abstract
In this research the authors measured radon gas concentration inside Hakama homes and calculated equivalent radiation doses in the study area. The study started from 1 June 2011 to 1 September 2011. Study area was divided into four sectors (H East, H West, H North and H South). About 200 dosimeters containing highly pure CR-39 were distributed randomly among the houses of the different sectors. Two dosimeters were distributed in each house (first in the living room and the second in the guest room). The indoor dosimeters were collected after three months. The collected detectors were chemically etched using 30 % KOH for 8 hours at 70 °C. An optical microscope was used to measure the nuclear alpha track density on the detectors surfaces. The author found that the average radon concentration in the study area was ranged from 30.2 Bq/m3 in the sector H East to 25.7 Bq/m3 in the sector H South. Moreover; the average radon concentration in the living rooms in the study area was 18.8 Bq/m3 which is below that in the guest rooms 37 Bq/m3. Radon contributes in increasing of absorption radiation dose. The calculated equivalent radiation dose in the study area was 0.68. The average radon concentration in the study area was below the Jordanian national level.

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.
