Is our basement air safe?: home radon test.

A home in Rapid City, SD has never been tested for radon, an invisible gas that is the second-leading cause of lung cancer in the US. A simple lowest-level test gives the family a real number.

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

occupancy notes + entry-pathway photos + GPS + EPA-protocol test placement + pCi/L result + mitigation-readiness plan

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Bring

• EPA-listed radon test device (short-term charcoal / alpha-track kit or a continuous radon monitor)
• camera
• tablet/clipboard with the EPA radon protocol + 4 pCi/L action-level reference + NRPP/NRSB certified-professional lookup
• flashlight (foundation, sump, crawlspace, service penetrations)
• tape measure (test-placement height + foundation/entry-pathway mapping)

Steps

1. 1. Sit with the household first: what prompted the concern (a neighbor's result, a basement bedroom/playroom, a real-estate transaction, a known Zone 1 county)? Who spends time on the lowest lived-in level and how many hours, children, sleeping areas, and any smokers (radon + smoking multiplies lung-cancer risk)? Record any prior test and its placement. Capture their concerns in their own words.
2. 2. Map and photograph the foundation and the lowest lived-in level: slab / crawlspace / full or walk-out basement, sump pit, drain tile, floor and wall cracks, and service penetrations, the soil-gas entry pathways a mitigation system would address.
3. 3. Guide correct placement of the EPA-protocol test: lowest lived-in level, ≥20 in. above the floor, ≥3 ft from exterior walls/windows/doors, away from drafts, heat, and humidity; NEVER in a kitchen, bathroom, or laundry. For a short-term test, establish closed-house conditions (windows/exterior doors shut, normal HVAC) 12 hours before and throughout. Record the device type, start time, and duration.
4. 4. Record the radon result in pCi/L and interpret it against the EPA 4 pCi/L action level. If the result is at or above 4 pCi/L, note that the EPA recommends a confirming follow-up (a second short-term test or a long-term test) before committing to a permanent system; if a continuous monitor was used, note the hourly variability.
5. 5. Where mitigation is warranted, scope a sub-slab depressurization readiness plan as a spec for a certified installer, candidate suction-point location, sump/drain-tile tie-in, fan location and vent-stack routing above the eave/roofline, electrical availability, and the required post-mitigation re-test. This is a scope, NOT an installation; no drilling, sealing, or fan is fitted.
6. 6. Assemble the plan with the household: the current radon picture, whether action is warranted, the mitigation scope with a rough cost band, and the NRPP/NRSB-certified-professional path. Note interim risk-reduction steps (increase ventilation, avoid using the lowest level as a bedroom for vulnerable occupants) for the window before mitigation.
7. 7. Review the plan WITH the household so they own the result and the next step; enter photos, GPS/address, test placement + type + result, the action-level interpretation, and the mitigation-readiness plan; sign. The family's claim of safe air = this plan + this evidence, Real (tested and mapped), Proven (photo + GPS + result + signature), One-of-one (this home, this foundation, this occupancy).

What counts as done

• Household's radon concerns + lowest-lived-in-level occupancy recorded
• Foundation type + radon entry pathways photographed
• EPA-protocol test placement documented
• Radon result in pCi/L vs the 4 pCi/L action level
• GPS / address confirm
• Mitigation-readiness plan where warranted

Proof is measured against these, not judged by taste.
