A GIS Approach to Produce a Map of the Potential for Radon in Indoor Air in Nova Scotia
Bibliographic record
Abstract
The Mineral Resources Branch initiated a project in 2007 utilizing a GIS-based approach to produce a map of the province showing the potential for radon in indoor air (O’Reilly et al., 2010). Radon is a naturally occurring, radioactive gas produced from the radioactive decay of uranium, and is the second leading cause of lung cancer after smoking and is the leading cause of lung cancer in non-smokers. There have been studies in the past (e.g. Jackson, 1990) that clearly demonstrate certain geological regions of the province are prone to having homes exceeding the Health Canada established guideline of 200 mBq/m for radon in indoor air. In some cases, homes as high as 20 times the guideline have been reported. No region in the province is devoid of homes exceeding the Health Canada guideline, which leads government to recommend that all homeowners should test their home for radon. However, it is thought that a map showing regions where there is a higher likelihood of having homes in exceedence would be useful to other government agencies, land-use planners, real estate agents and the general public.

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.
