چکیده

در این مطالعه با استفاده از نرم‌افزار PHAST نمودارهای غلظت برحسب زمان در فواصل و ارتفاع‌های مختلف از محل آلودگی اولیه عامل HCN در چند سناریوی مختلف استخراج گردیدند. در فاصله‌های مختلف از محل آلودگی اولیه و ارتفاع 2 متری از سطح زمین، حداکثر میزان غلظت HCN مربوط به شرایط جوی خنثی است. با افزایش فاصله از محل آلودگی اولیه در ارتفاع 2 متری از سطح زمین، غلظت HCN کاهش یافته درحالی‌که مدت زمان آلودگی منطقه افزایش پیدا کرده است. در یک فاصله خاص از محل آلودگی اولیه، با افزایش ارتفاع از سطح زمین، غلظت HCN افزایش یافته است. نتایج این مطالعه نشان می‌دهند که وضعیت جوی خنثی، بدترین وضعیت برای اقدامات حفاظتی و پدافندی است چرا که غلظت بیشتری از HCN در منطقه وجود داشته و مدت زمان آلودگی نیز بیشتر است.

چکیده [English]

The aim of this study is construction of graphs of concentration versus time at different distances from the primary pollution place of the HCN agent and also the production of well tabulated data for the amount of HCN released at different distances and heights from the location of primary pollution using the PHAST software. At different distances from the primary pollution place and 2 meters height from the ground, the maximum concentration of HCN was due to neutral weather condition. With increasing the distance from 2 meters above the ground, the concentration of HCN decreased while the duration of contamination in area increased. At a certain distance from the primary pollution place, with increasing the height, the concentration of HCN increased. The results of this study indicate that the neutral weather condition is the worst condition for defensive protection actions, because there was a higher concentration of HCN in the region, and the duration of contamination has also been higher.
