Determination of radon concentration level and its progenies in breast cancer using Cr-39 NTD

Background: Alpha particle is massive and causes a great lot of ionization when it gets into contact with a body or ingested, and causes single strand and double strand DNA breaks. Two of the alpha emitting decay products, namely 218Po, 214Po, deliver the majority of the radiogenic dose and have been identified as the primary cause of radon-induced cancer. Objectives: This study aims to measure the concentration of radon in powdered blood samples of human have problem with breast cancer in Kurdistan Iraqi region Methods: This study was carried out to detect and measure the concentration of radon in powdered blood samples from the human have problem with breast cancer in Kurdistan Iraqi region from (Sulaymania and Erbil) by using CR-39 NTD (passive method). Results: The activity concentrations of radon of blood human suffer breast cancer ranged from highest value (27.832) Bq.m-3 in (CP3- Taslwja town) to lowest value (13.961) Bq.m-3 in (CP4- Barda qaraman town) with average value of activity concentrations of radon (24.076) Bq.m-3 in Sulamania governorate (Hewa center for cancer). Also the results showed that the activity concentrations of radon ranged from highest value (39.591) Bq.m-3 in (CP73- Taqtaq town) to lowest value (10.251) Bq.m-3 in (CP74- Kasnazan town) with average value of activity concentrations of radon (22.045) Bq.m-3 in Erbil governorate (Nana kaly center for cancer). The results showed that the radon concentration in powdered blood samples were lower than the global permissibility limiting of exposure to radon 200 Bq.m−3. Conclusions: The variation in concentrations of radon in different locations may be arisen due to the difference in the nature of blood samples and nuclei content in this samples, also depending on the allergic reaction of the body to radiation. The issues in this research are very important in strengthening the link between radon, radon progeny, and blood for human have problem with cancer in Kurdistan Iraqi region
