10. 1 2006 A New Automatic EVaporation System for Fallout Measurement Masaaki Saito Norio Kato A continuous evaporation system was developed Sample water was continuously supplied to rotary evaporator with a tube pump The tube pump was controlled by a water level sensor placed in a sample flask A condenser was turned upside down and droplets of water were continuously removed by an aspirator The merits of the system are as follows 1 labor saving with continuous day and night unmanned operation 2 no generation of water vapor In a room 3 very safe with only 60 C heating temperature 4 20L of sample water per day can be evaporated Keywords Automatic evaporator Rain Fallout Environmental radioactivity 1
