Series note: July 2026 report series, Fylde Papers archive

This archive accompanies the technical note Comparative Review of Time-Resolved Gamma Survey Data Along the Preston New Road Corridor. It preserves native RadiaCode-103 measurements collected during February and July 2026, together with contextual measurements from additional survey dates. The deposit contains 13 accumulated XML spectra, seven GPS count-rate tracks, two master time-resolved spectrograms, a master measurement register, the final technical note, a README, citation metadata, licence information and a SHA-256 file manifest. The same detector, a RadiaCode-103 with serial number RC-103-010950, and the same energy calibration were used throughout. The February elevated-verge point and the July access-cover point are different locations. The archive therefore does not demonstrate persistence of a single hotspot through time. It documents sustained local count-rate variation at two separate points, with moving-track data providing wider spatial context. In February, the principal near-surface accumulation averaged approximately 9.13 counts per second, compared with 4.36 counts per second at a nearby baseline and 6.35 counts per second at a raised comparison. In July, the access-cover measurement averaged approximately 6.09 counts per second near the surface and 5.66 counts per second at approximately waist height. Three other fixed July measurements averaged approximately 5.19 counts per second, while a local-low control averaged approximately 3.45 counts per second. The XML accumulations, GPS tracks and time-resolved spectrograms agree closely and show that the principal elevations were sustained across their measurement periods rather than arising from isolated transient spikes. The spectra show broad increases in count density and modest changes in spectral hardness, but no securely resolved diagnostic photopeak. The data do not establish radioactive contamination, radionuclide identity, harmful exposure, source, mechanism or attribution to hydrocarbon operations. Their purpose is to preserve an auditable screening record and support consideration of a professional calibrated verification and characterisation survey. This record forms part of the July 2026 report series within the wider Fylde Papers archive.
