Evaluation of natural radioactivity and radiological hazards in concrete aggregates for radiation shielding applications.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study assessed the natural radioactivity and associated radiological hazards in selected concrete aggregates barite, magnetite, hematite, river sand, and Dangote cement intended for radiation shielding applications. The activity concentrations of ²²⁶Ra, ²³²Th, and ⁴⁰K were measured using a NaI (Tl) gamma-ray spectrometer at the Centre for Energy Research and Training, Ahmadu Bello University, Zaria. The corresponding radiological hazard indices were subsequently evaluated using standard models. The mean activity concentrations ranged from 15.8 ± 0.3 to 217.5 ± 2.8 Bq kg⁻¹ for ²²⁶Ra, 27.2 ± 4.5 to 101.4 ± 1.0 Bq kg⁻¹ for ²³²Th, and 46.9 ± 0.4 to 334.5 ± 6.6 Bq kg⁻¹ for ⁴⁰K. The highest ²²⁶Ra and ²³²Th activities were recorded in magnetite (217.5 ± 2.8 Bq kg⁻¹ and 101.4 ± 1.0 Bq kg⁻¹, respectively), while the maximum ⁴⁰K concentration (334.5 ± 6.6 Bq kg⁻¹) occurred in river sand. These values generally fall within or below global averages of 32 Bqkg
