  "name": "Sleeping-area assessment (full four-quantity survey)",
  "summary": "The combined survey building-biology practice applies to a bedroom: RF power density, AC magnetic field, AC electric field and body voltage, each graded against its own band.",
  "status": "verified",
  "lastVerified": "2026-08-12",
  "data": {
    "aliases": [
      "bedroom EMF survey",
      "sleeping area survey"
    ],
    "goal": "Produce a single defensible picture of a sleeping area across all four exposure quantities, with mitigation ordered by measured contribution.",
    "quantity": "power-density",
    "equipment": [
      "broadband-rf-meter",
      "elf-gaussmeter",
      "ac-electric-field-meter",
      "body-voltage-kit",
      "data-logger"
    ],
    "steps": [
      "Run the RF room survey, the ELF magnetic survey and the body-voltage measurement in that order, at the pillow position.",
      "Grade each result against the corresponding SBM-2024 band, and separately against the applicable regulatory limit, and report both.",
      "Rank the four quantities by how far each sits into its own precautionary band — this ranking, not intuition, determines what to fix first.",
      "Apply one mitigation at a time and re-measure only the affected quantity before proceeding.",
      "Re-run the full survey after all mitigations and archive both datasets with dates."
    ],
    "pitfalls": [
      "Buying shielding before measuring, which is the most common and most expensive mistake",
      "Fixing the most-discussed source rather than the largest measured one",
      "Treating SBM precautionary bands as legal limits, or regulatory limits as safety targets — they answer different questions",
      "Changing several things at once, leaving no way to attribute the improvement"
