Activity concentrations are identical to Table 1; not-detected ⁴⁰K was treated as zero. Sample IDs 30, 32, and 42 are absent because a series activity could not be quantified. Workshop sample values are reference calculations and were not used in the residential interpretation. N/A, not applicable (Distance and Depth are undefined for workshop samples). These are screening estimates under generic occupancy assumptions, not measurements of individual dose or risk.</p> <p>(XLSX)</p> 2026-10-05T17:27:38Z Dataset Dataset 10.1371/journal.pone.0348187.s002 https://figshare.com/articles/dataset/_p_Radiological_screening_indices_for_the_43_samples_with_quantifiable_sup_238_sup_U-_and_sup_232_sup_Th-series_activities_with_the_underlying_activity_concentrations_in_machine-readable_form_p_/34071559 CC BY 4.0
