Recently, serum, whole blood, and other body fluids or components were utilized as "biomarkers" to assess the levels of radioactive elements, including radon. When exposed to radioactivity, human cells' structure, function, or both, are impacted. That way, various factors are considered when analyzing radioactivity's risk and safe rates.

The research project attempted to determine hazards for radon concentration in the human body, evaluate them between blood and serum samples, and link them to high blood pressure.

To determine the levels of radon, 40 human samples were taken. 20 volunteers ten healthy, ten hypertension. Solid nuclear track detector CR-39, was utilized to record the radioactive values, while SPSS v 23 was used in statistical comparisons.

The findings demonstrated that blood samples from hypertension individuals had the greatest levels of radon concentrations, activity, and yearly effective dose with 12.19 Bq/m^3, 0.117Bq and 2.94 mSv/y respectively, compared to the rest of the samples. In contrast to the other samples, the healthy serum group had the greatest value of the work safety factor with (11.45*10-4).

Although the radon values of the samples in the air and the annual activity did not exceed the permissible global percentages, they constituted an indicator of the occurrence of diseases, and this has been proven through research that patients have the highest values. The differences in the recorded values are due to different environmental and human factors, it can be inferred from the results that blood samples were more effective in detecting radiation compared to serum.
