A scoping review of uranium and other radioactive heavy metals in breast milk and their impact on early life health.
Review in Journal of perinatology : official journal of the California Perinatal Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundRadioactive heavy metals, including uranium, strontium-90, caesium-137, radium, thorium, and plutonium, pose potential health risks to nursing infants through breast milk transfer. Understanding the extent of contamination, transfer mechanisms, and health implications is critical for public health policy.
objectiveThis scoping review synthesises evidence on radioactive heavy metal contamination in breast milk, maternal-infant transfer mechanisms, and associated health impacts on early life development.
methodsA comprehensive scoping literature search was conducted in December 2024 across multiple electronic databases. After deduplication, 161 unique papers remained. An AI-assisted relevance scoring approach (SciSpace biomedical agent) was used to prioritize screening; final eligibility decisions and data extraction were performed by the authors. Thirty studies were included for synthesis.
resultsEvidence demonstrates measurable concentrations of strontium-90, caesium-137, uranium, and radium in breast milk following environmental contamination events (Chernobyl, Techa River, nuclear weapons testing) and in regions with naturally elevated radioactivity. Transfer rates vary by radionuclide, with strontium-90 showing significant maternal-infant transfer. Biokinetic models indicate dose-dependent accumulation in infant tissues. Limited direct evidence exists for specific health outcomes, though theoretical risk assessments suggest potential impacts on hematopoietic development, bone metabolism, and long-term cancer risk.
conclusionsWhile breast milk contamination with radioactive heavy metals is documented in specific contexts, the health benefits of breastfeeding generally outweigh risks except in acute high-exposure scenarios. Gaps remain in understanding long-term neurodevelopmental and growth impacts. Enhanced biomonitoring and longitudinal studies are needed to inform evidence-based public health guidance.
