During the operational history of the Savannah River Site (SRS), many different radionuclides have been released from site facilities into the SRS environment. However, only a relatively small number of pathways, most importantly (137)Cs in fish and deer, have contributed significantly to doses and risks to the public. The "effective" half-lives (Te) of (137)Cs (which include both physical deca...

پراکندگی فوتون های گاما به سمت عقب از سطح یک ماده را پس پراکندگی پرتوهای گاما می گویند. در این پژوهش حفاظ های سربی، آلومینیومی و آهنی به شکل دیسک به ضخامت تقریباً 1/0 سانتی متر و قطر 18 سانتی متر ، به منظور بررسی پس پراکندگی تهیه شدند. همچنین یک چشمه ی سزیم 137 بین حفاظ و آشکارساز یدورسدیم قرار داده شد و طیف گامای چشمه ثبت گردید. به منظور بررسی تأثیر ضخامت حفاظ در میزان پس پراکندگی گاما، در هر م...
background: two of the important radionuclides which are entered to environment and human diet are radium-226 (226ra) and cesium-137 (137cs). it is clear that the methods for preparation of foods such as peeling, washing, cooking or frying can affect the dose which is received by human due the to consumption of foodstuffs. an experiment has been performed at the environmental monitoring section...

Schizophrenia is a complex genetic disease and characterized by affective, cognitive, neuromorphological, and molecular abnormalities that may have a neurodevelopmental origin. MicroRNAs (miRNAs) are critical to neurodevelopment and adult neuronal processes by modulating the activity of multiple genes within biological networks. MiR-137 as a brain-enriched microRNA, plays important roles in reg...
