PLANT FOR AUTOMATIC PREPARATION AND PROPORTIONING WATER CONCENTRATE OF RADON Russian patent published in 2009 - IPC G01F13/00 A61H33/06 

FIELD: physics, nuclear physics.

SUBSTANCE: invention relates to medical equipment and is intended for decreasing dosage load on personnel and radon less in pouring radon into portion vessels, thus adding to radiation safety. To this end, in compliance with the proposed invention, the plant comprises a mixing tank incorporating centrifugal pimp designed to dissolve radon in water, switching valves and electronic proportioner. Note here that aforesaid electronic proportioner consists of a solenoid valve incorporating AC choke, time counter to set the required solenoid valve opening time, when the valve allows the preset portion of proportioned radon volume to pass through, and power supply. The plant includes also the switching valve for the air-radon mix to pass through from the radon generator into aforesaid mixing tank, and the switching valve to pass the obtained radon concentrate solution to proportioner.

EFFECT: reduced dosage load on personnel, lower loss of radon in pouting in pouring it into portion vessels which adds to radiation safety.
