Assessment of gamma and neutron shielding features of Se
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
The ternary transition-metal chalcogenide system possesses high potential in various fields of science and technology. The present report highlights a comparative study on the high-energy radiation shielding properties of transition metals as chemical modifiers in the Se80 − yTe20My (M = Fe, Co, Ni, Cu, y = 0 and 2) chalcogenide series, spanning a broad photon energy range of 15 keV to 15 MeV. The radiation shielding capability of the studied materials against high-energy radiation, such as X-rays and gamma rays, was evaluated using Phy-X/PSD software and experimentally validated. Various parameters essential for evaluating radiation shielding performance were investigated, including MFP, HVL, LAC, MAC, Zeff, Neff, Zeq, RPE, TF, EABF, EBF, and FNRCS (ΣR). Among the studied samples, the Fe incorporated sample (STFe) exhibited the most effective shielding performance. At 0.015 MeV, it recorded the highest LAC (~ 413.87 cm⁻¹) and a MAC of 87.498 cm²/g, values significantly higher than those of standard shielding materials. STFe showed the lowest HVL and MFP at 0.015 MeV, confirming its strong gamma-ray shielding. It also had the highest FNRCS (0.076 cm⁻¹), indicating excellent neutron protection. Its excellent performance arises from its higher density.
