# SF-001 — Transient balance changes at 7 tesla

Why this matters
This retrieval lead concerns temporary balance effects around a very strong MRI magnet. Such effects could matter to the experience of a scan and to work near scanners. The original experiment still needs review; an MRI static field is physically different from a phone or Wi-Fi signal.

Topic: Intermediate and static fields

Verification Group: Retrieval lead

Record Role: Retrieval lead

Featured: False

Exposure: Tesla-scale MRI static magnetic fields and motion through gradients.

Design: Human experiment.

Finding: Affirmative vestibular or neurobehavioural finding described in discovery dossier.

Boundary: Retained in a separate regime-specific catalogue. No inference to Wi-Fi or mobile-phone exposures.

Protection Question: How might temporary balance changes affect scanning or work near strong MRI magnets? The original experiment remains to be reviewed; this static-field lead cannot support a phone or Wi-Fi protection claim.

Access: Record verified; full text still required
