Abstract: The estimation of (²²²Rn, ²²⁶Ra, and ²³⁸U concentrations in human blood is very important to assess the radiation exposure. The fission track method is used to detect alpha emitters in the blood of patients with kidney failure in Najaf, Iraq. The study found that uranium concentrations in renal failure blood tests ranged from 1.507 ± 0.24 ppb to 0.104 ± 0.41 ppb in non-smokers, while radon concentrations ranged from 8.763 ± 0.00246 Bq/m³ to 0.61 ± 0.0606 Bq/m³, and radium concentrations from 0.353 Bq/m³ to 0.024 Bq/m³. In contrast, healthy non-smokers had uranium concentrations between 1.014 ± 0.23 ppb to 0.078 ± 0.36 ppb, radon concentrations between 5.897 ± 0.012 Bq/m³ to 0.457 ± 0.071 Bq/m³, and radium concentrations between 0.237 Bq/m³ to 0.018 Bq/m³. The study found that individuals with renal failure have higher alpha emitter levels, 1.5 times higher than the healthy group, and these levels increase with age and are higher in women.
