This study investigated the long-term health effects on 675 individuals exposed to ionizing radiation at Semipalatinsk and Chornobyl, and those involved in the Soviet–Afghan war. Results showed a higher prevalence of cardiovascular diseases, notably hypertension (55%) and cardiac ischemia (32.9%), compared to the general population. The findings highlight the need for early detection of cardiovascular and central nervous system disorders in these groups, emphasizing tailored treatment and prevention strategies.
