To use radioactive Ar-clathrate in industrial field, a shielding and transportationcontainers have been fabricated that can recover Ar gas with alcohol and inject it into industrialprocesses. For evaluating the shielding suitability of the transport container, a Monte Carlosimulation was performed. When 41Ar 100 mCi was transported using the container, it was lessthan 0.4 mSv·h-1 at the point where the surface dose rate was highest. In addition, as a resultof calculating the internal temperature of the Ar-clathrate during irradiating neutrons, whenirradiated at the point where the thermal neutron flux of the HANARO reactor is highest, it is77℃, so that radioactive argon gas can be stably produced without decomposition or melting ofAr-clathrate.
