Interaction of low-intensity nuclear radiation dose with the human blood: Using the new technique of CR-39NTDs for an in vitro study

Demonstrating a relationship between ethnics, radionuclide activity, and the element contents in the tooth samples using HPGe detector and XRF technique

This study proved a relationship between levels of natural radioactivity concentrations and element concentration (ppm) in tooth samples with the ethnic groups using high purity germanium (HPGe) detector and X-ray fluorescence spectrometers (XRF), respectively. The evaluations have been done for 60 tooth samples for different ethnic groups (Kurd, Arab, Turkman, Persian, and Christian" Chaldean Catholic") of the population living in Erbil- Iraq. The results indicated that the high and low levels of radionuclide concentration in teeth samples found in ethnic groups (Turkman and Christan), and (Kurd, Arab, and Persia), respectively. The level of element contents (Na, Ar, Kr, As, Ti, Pt, Eu, Dy, and Pm) was high in teeth samples of Turkman and Christan and zero in teeth samples of Kurd, Arab, and Persia. Response of ethnic groups of Turkman and Christain was similar each to other. Responses of Kurd, Arab, and Persia ethnic groups was similar with each other regarding the XRF results.

Influence of the static magnetic field on red blood cells parameters and platelets using tests of CBC and microscopy images

The present study was undertaken to investigate the influence of the static magnetic field (SMF) on the platelets and red blood cells counts (RBCs), haemoglobin (HGB), haematocrit (HCT), mean cell volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) in female rats (in-vitro). The results were analysed using tests of complete blood count (CBC) and microscopic images. The SMF in millitesla (mT) was generated using a fabricated electromagnetic exposure technique, and it has used for different time (minutes) of exposure. Statistical analysis for both tests investigated that the values of SMF affected the RBCs parameters and platelets for exposed Rats significantly for both tests. At 42.5 mT: RBCs counts have been affected (decreased) significantly (p < 0.05) at 30 min exposure, HCT (%) has affected (increased) significantly (p < 0.05) at 10 min and 30 min of exposure. The highest effects of SMF on the values of RBCs, HGB and HCT (%) were found at 34.8 mT after exposed to 15 min Variation of time of exposure and the values of SMF affected (p < 0.05) on the values of RBCs, HGB and HCT (%). The lowest effect of SMF was on the value of MCV (fl) at 6.4 mT at 15 min We found the effects of SMF on the platelet counts significant. Microscopy images of RBCs parameters and platelet count (PLT) support results got from the CBC test.
