Abstract

Ionising radiation from diagnostic procedures poses significant occupational risks to healthcare workers (HCWs), yet awareness remains suboptimal in many settings, particularly in low- and middle-income countries. This cross-sectional study assessed radiation protection knowledge and awareness among 140 HCWs from inpatient, intensive care, and emergency units in Indonesia, identifying independent predictors of awareness. Knowledge was evaluated using a validated 15-item instrument (categorized as poor, acceptable, or good), while awareness was measured as a binary outcome. Data were analyzed using Pearson’s chi-square test and multivariable binary logistic regression, adhering to STROBE guidelines. The sample was predominantly female (69.3%) with bachelor’s degrees (57.1%). Overall, 46.4% demonstrated good knowledge, 48.6% acceptable, and 5.0% poor, while 68.6% were classified as aware. Multivariable analysis revealed that knowledge level was the sole independent predictor of awareness: compared to poor knowledge, acceptable knowledge significantly increased awareness odds (aOR = 3.48; 95% CI: 1.12–10.80; p = 0.031), as did good knowledge (aOR = 8.65; 95% CI: 2.10–35.60; p = 0.003). These findings confirm that radiation protection knowledge strongly and independently drives awareness among clinical staff. Consequently, healthcare institutions must prioritize continuous, evidence-based radiation safety education—particularly for personnel in high-exposure units—as the foundational strategy to effectively bridge the knowledge–awareness gap and mitigate occupational radiation risks.

Abstract

Rising global temperatures and increasing frequency of extreme heat events have transformed thermal stress into a critical, systemic driver of cardiovascular and chronic disease burden worldwide. Despite growing recognition of heat-related health risks, substantial gaps remain regarding chronic sub-threshold exposure, morbidity outcomes, and the equity implications of adaptation strategies. This systematic review, conducted according to PRISMA 2020 guidelines, synthesizes contemporary epidemiological evidence from peer-reviewed studies published between 2020 and 2025 to characterize heat-health associations, identify vulnerability determinants, and evaluate policy implementation across diverse geographic and socioeconomic contexts. Following independent screening, quality appraisal, and data extraction, a structured narrative synthesis was performed due to significant methodological heterogeneity in exposure metrics and outcome definitions. The findings demonstrate a robust association between heat exposure and elevated risks of stroke, coronary heart disease, and accelerated progression of metabolic, respiratory, and mental health conditions, with chronic thermal stress emerging as an underrecognized contributor to long-term physiological deterioration. Vulnerability is highly stratified, disproportionately affecting older adults, women, outdoor workers, socioeconomically marginalized communities, and populations in low- and middle-income countries, particularly within urban heat island environments. Current adaptation measures exhibit limited behavioral uptake and insufficient equity-focused design. Addressing these disparities requires standardized exposure metrics, context-sensitive early warning systems, multisectoral policy integration, and targeted research on chronic thermal stress to build inclusive, climate-resilient health systems.
