Abstract—Risks evaluation of alpha particles deposition on human blood has been performed by using new exposure techniques of CR-39 NTDs. The method of distribution of alpha particles and radiation dose on the surface of CR-39 NTDs showed that human blood samples have significantly improved. Platelet (PLT), red blood cells (RBC) and white blood cells (WBC) counts were found to be relatively affected. However, the most was the PLT count, which decreased with increasing radiation dose of alpha particles. In addition, comparative study of CR-39 NTDs and the human blood samples is a new technique for in vitro studies of blood ionization. In the present exposure technique, the radon concentration reduced to around 4.915 %, and thus, around 95% of the radon concentration was saved. A ratio of the deposition of alpha particles was found to be adequate to change the PLT count in both males and females.

Index Terms—Human blood, CR-39 NTDs, Radon-222, Alpha particles.
