چکیده

مطالعات بسیاری در ارتباط با عوامل مؤثر بر خروج گاز رادن به‌عنوان پیش‌نشانگر زلزله انجام شده است. در این مطالعه، اثر میدان مغناطیسی مورد توجه قرار گرفته است. برای این منظور، تأثیر میدان‌های مغناطیسی ضعیف (حداکثر 40 گوس) از سد صافی‌های نازک از جنس کاغذ و آلومینیوم مورد آزمایش قرار گرفته است؛ به‌طوری‌که هنگام استفاده از صافی کاغذی در رطوبت کمتر از 10%، ضریب نفوذ رادن از مقدار برای میدان مغناطیسی صفر تا مقدار برای میدان مغناطیسی 5/39 گوس و هنگام استفاده از صافی آلومینیومی در رطوبت کمتر از 10% از مقدار برای میدان مغناطیسی صفر تا مقدار برای میدان مغناطیسی 5/39 گوس به‌دست آمد.

چکیده [English]

Various studies have been done on the effective factors that cause the emanation of radon gas as the earthquake forecast from the earth. In this study, Magnetic field is examined and the effect of weak magnetic fields of up to 40 gauss applied to paper and aluminum membranes is measured. The results indicate an increase in the diffusion coefficient versus the increase of the applied magnetic field. It is revealed that by using a paper membrane at moistures lower than 10%, the diffusion coefficient of radon is in the absence of the magnetic field and is for a magnetic field of 39.5 G, and when using an aluminum membrane at moistures lower than 10%, it is in the absence of the magnetic field and is for a magnetic field of 39.5 G.
