[ 1 ] - تولید آشکارساز سوسوزن سولفید روی آلاییده با نقره[ZnS(Ag)] برای شمارش ذرات آلفا
In this research, Zinc Sulfide doped with Silver (ZnS:Ag) powders were synthesised on Nitrogen atmosphere for detection of alpha particles by chemical Co-precipitation method. Different concentrations of Silver ions were investigated to optimize impurities amount for achive best alpha counting efficiency. Optical and structural characteristics of the synthesized powder using Photoluminescence S...
[ 2 ] - The feasibility of using microstrip gas detector as radon detector for earthquake prediction
In the last decade, several studies have concluded that elevated concentrations of radon gas in soil or groundwater could be the sign of an imminent earthquake. It is believed that in case of sudden movement of rocks before earthquake, radon is released from the depth of ground and reached the surface. In this way, by measuring Radon concentration change, earthquake prediction is possible. In t...
