Geiger readings remain elevated at capture site three decades later

The survey was conducted by an independent radiological consultant using a calibrated handheld gamma counter and a GPS-tagged grid pattern over the alleged primary capture site. The consultant ran two passes on the same day, four hours apart, and obtained consistent readings on both. A third pass two weeks later by a different operator with a different instrument reproduced the result within tolerance.

Background gamma readings across the survey area are consistent with regional baseline at every point except a discrete oval footprint of approximately sixteen square meters. Within that footprint, readings are between two and four times the surrounding baseline, with a peak near the geometric center.

The anomaly has not migrated. Comparison with an informal 2009 reading taken by a different consultant, also tagged to GPS, shows the footprint at the same location and at comparable intensity. There is no documented municipal, industrial, or medical use of the parcel during the period.

Persistent low-level gamma elevation can have many causes. The consultant is explicit that the survey establishes the anomaly and rules out routine explanations within the parcel; it does not establish the source. He recommends, in the report, that core sampling be performed by an institution with appropriate handling capacity. No institution has agreed.
