# Log EMF measurements

> Record room-by-room EMF readings, rate them against building-biology thresholds, and include them in AI context and recommendations.

The EMF Assessment is for measured electromagnetic-field readings in the places where you spend time. It lives inside the **Environment** context card and is included in AI context, export/import, sync, and recommendations.

Use it when you have meter readings from your bedroom, office, living room, or a professional building-biology report and want those measurements to be interpreted alongside your labs, sleep, light, and symptoms.

## Where to find it

<Steps>
  <Step title="Open Manage → Context">
    Open **Insight → Manage → Context**, or add the context widget to your dashboard and open **Environment**.
  </Step>

  <Step title="Open EMF Assessment">
    In the Environment card, click **Open EMF Assessment**.
  </Step>

  <Step title="Add rooms and readings">
    Add a room, mark whether it is a sleeping area or daytime area, then enter readings from your meter or consultant report.
  </Step>
</Steps>

## What to record

| Measurement              |  Unit | Typical source                                       |
| ------------------------ | ----: | ---------------------------------------------------- |
| AC electric fields       |   V/m | wiring, ungrounded lamps, bedside cables             |
| AC magnetic fields       |    nT | transformers, panels, appliances, nearby power lines |
| RF / microwave radiation | µW/m² | WiFi, phones, cell towers, smart meters              |
| Dirty electricity        |    GS | switching power supplies, dimmers, solar inverters   |
| DC magnetic deviation    |    µT | steel beds, magnets, local magnetic-field distortion |

Each room can also include source tags, mitigation tags, notes, and photos of meter readings or room setup.

## How getbased rates readings

getbased grades each measurement against SBM-2015-style building-biology thresholds. Sleeping areas are treated more strictly than daytime rooms because you spend more recovery time there.

The rating colors are meant to help you prioritize, not to diagnose disease:

| Rating          | Meaning                                  |
| --------------- | ---------------------------------------- |
| No concern      | Nothing obvious in the reading           |
| Slight concern  | Worth watching or retesting              |
| Severe concern  | Likely worth mitigation if repeatable    |
| Extreme concern | Highest-priority exposure to investigate |

<Note>
  Meter technique matters. Distance, orientation, body shielding, background signals, and meter bandwidth can change readings. Treat one measurement as a clue; repeat measurements before making expensive changes.
</Note>

## AI interpretation

Click **Interpret** inside the EMF editor to ask the active AI provider to synthesize the room-by-room readings. The interpretation can explain likely sources, rank the rooms by priority, and suggest mitigations.

If you save multiple assessments, getbased can compare before/after readings so you can see whether a mitigation actually changed the measurement.

## Import professional reports

If you have a consultant PDF or photo report, import it from the EMF Assessment. getbased uses the same AI import/review pattern as lab reports: extract readings, review them, then save the structured snapshot.

## How EMF data affects the rest of getbased

* **AI chat** receives a summary of saved EMF assessments as part of profile context.
* **Recommendations** can suggest mitigation steps, meters, or products when your readings are high enough to warrant attention.
* **Sync/export/import** include saved assessments with the profile.
* **Environment context** still keeps the simpler high-level EMF/source fields; the assessment is for measured room-level detail.

<Warning>
  EMF recommendations are informational. getbased cannot prove that a reading caused a symptom or lab result. Use the assessment to organize measurements and decisions, and consult a qualified building-biology or electrical professional for remediation work.
