Original datasets, with their methodology attached
8 published datasets, 1,467 rows, every one with its provenance, field schema, limitations, and a downloadable CSV and JSON. Plus 3 collection instruments published before the data exists.
That last part is the unusual one, so it is stated plainly rather than buried: this platform has collected zero quotes and zero contractor interactions to date. The datasets that would require those observations carry N = 0 and a published methodology, rather than a modelled figure presented as a measurement. Our editorial policy forbids the alternative.
Published datasets
Each of these has rows today. Provenance says where a row comes from — derived from the platform’s own registries, or an original classification we authored.
| Dataset | Rows | Provenance |
|---|---|---|
| State Radon Regulatory Index Ten states, one table: regime, agency, disclosure mechanism, and what is actually required. | 10 | Derived from the platform registry |
| Radon Connect Coverage Index Every market, territory, and city page this platform publishes, as one table. | 35 | Derived from the platform registry |
| Radon Mitigation Cost Driver Index The variables that move a quote, their direction, and their relative magnitude — no invented dollar figures. | 18 | Original editorial taxonomy |
| Mitigation System Component and Service-Life Dataset What each part does, how it fails, and whether you would notice. | 10 | Original editorial taxonomy |
| Radon Testing Method Comparison Dataset Which method answers which question — and which decisions each one cannot carry. | 5 | Original editorial taxonomy |
| Home-Sale Radon Negotiation Outcome Taxonomy Four outcomes, what drives each, and who carries the risk afterward. | 4 | Original editorial taxonomy |
| Radon Terminology Dataset Controlled vocabulary with the misreading each term reliably attracts. | 22 | Original editorial taxonomy |
| Radon FAQ Corpus 1363 hand-written question-answer pairs, structured and downloadable. | 1,363 | Derived from the platform registry |
Collection instruments
Methodology, field schema, and release threshold published in advance. Fixing the definitions before the answer is known is what makes the first release trustworthy — and it is why we will not ship an estimate in the meantime.
| Instrument | Observations | First release at |
|---|---|---|
| Radon Quote Line-Item Comparison Dataset Instrument published, N = 0. What we will collect, and why we will not estimate first. | 0 | 250 |
| Contractor Response Time Dataset Instrument published, N = 0. Measured from real routed requests once intake is live. | 0 | 500 |
| Home-Sale Negotiation Outcome Frequency Dataset Instrument published, N = 0. The taxonomy exists; the distribution does not yet. | 0 | 300 |
