This study investigated hematological changes, serum TNF-α and IFN-γ levels in 42 people inadvertently exposed to radium-226 in Hilla City, Iraq. The study found significantly higher levels of the pro-inflammatory cytokines TNF-α and IFN-γ in exposed individuals compared to unexposed controls. There was a negative correlation between cytokine levels and complete blood count results. The results suggest that tiny doses of radium could induce TNF-α and IFN-γ, and that these cytokines may serve as biomarkers for radium exposure. Radium exposure was found to cause changes in pro-inflammatory cytokine levels and hematological parameters.
