| published |  | Rice is the second largest quantity staple international traded cereal and is produced in climatic areas favorable to aflatoxin production, which affects such trading. This review article is to show and explain the levels of aflatoxin contamination of rice worldwide; in general, the contamination is low and varies from country to country. However, the high daily intake of rice makes even these lower levels of concern, as aflatoxin B1 is carcinogenic and has been correlated with hepatocellular carcinoma (HCC) incidence in some countries. In addition, the analytical procedures, the permissible limits used worldwide have been reviewed and discussed. |

| نتيجة تجربة | | Zinc oxide nanoparticles is one of the most attractive nanomaterials and used on a large scale in many applications in the industry, environmental, medicine, because of availability , cheap, no health and environmental risk compared to the others nanomaterials. In this project, we are going to synthesize zinc oxide nanoparticles for use of liver cancer treatment and hepatitis prevention .This study includes a series of laboratory experiments by means of animals. Physical, chemical and morphological properties of blood and hemoglobin will be studied with emphasize on red blood cells. Moreover, histopathology, complete blood count and genetic materials will be examined. Rheometer and UV–Visible spectrophotometer will be used for blood characterization and X-ray diffraction, Fourier-transform infrared spectroscopy, Atomic force microscopy well be used for ZnO nanoparticles characterization. The project outcomes will highlight the influence of zinc oxide nanoparticles toxicity on liver cells. |

| أهمية رصد الإشعاع في مولدات التكنيشيوم المستنفد من أجل حماية العمال، والجمهور من الأخطار التي تشكلها النفايات المشعة. | | This study was carried out to survey and measure radioactivity concentration and estimate radiation dose level at the surface of spent technetium generator columns for the safe final disposal of radioactive waste. High resolution γ-spectrometry with the aid of handheld radiation survey meters has been used. The radioactivity measurements has shown that 238U, 40K and 137Cs were only measurable in one sample whereas 125Sb was found in 14 samples out of total of 20 samples with an activity concentration which ranged from 21 to 7404 with an average value of 1095 Bq/kg. The activity concentration of 125Sb is highly variable indicating that the spent 99mTc generator columns are of different origin. This investigation highlighted the importance of radiation monitoring of spent technetium generators in the country in order to protect workers, and the public from the dangers posed by radioactive waste. |
