Process for the removal of radioactive iodine from a liquid, especially urine, and apparatus to carry out the process

An apparatus for the removal of radioactive iodine from a patient's urine comprising:

• (A) means in a lavatory for collecting the patient's urine said means being provided with an outlet line arranged for removing the urine free from solids;
• (B) a reaction chamber having an inlet line and an outlet line;
• (C) a pump and a first magnetic valve connected in series between the outlet line of said collecting means and the inlet line of said reaction chamber;
• (D) a level sensor for said reaction chamber;
• (E) at least two containers for reaction solutions having means for supplying a dosed quantity of said reaction solutions to said reaction chamber, said means including an electrically operating metering pump in an outlet line of each container;
• (F) a mixing apparatus in said reaction chamber for mixing of said urine and said quantities of reaction solutions;
• (G) a pressure pump in said reaction chamber for the conveyance of the mixed liquid from said reaction chamber through its outlet line;
• (H) a filtration unit connected releasably to said outlet line of said reaction chamber via a second magnetic valve, said filtration unit having at least one outlet line;
• (I) a catch container having an inlet line releasably connected to said one outlet line of said filtration unit and having at least one outlet line, said one outlet line of said catch container being connectable via a third magnetic valve with a canalization system;
• (J) an electric control unit having at least one control inut connected with said level sensor in said reaction chamber and a plurality of control outputs connected with, respectively, with said pump in said outlet line of said collecting means, said first, second and third magnetic valves, said metering pumps, said mixing apparatus and said pressure pump in said reaction chamber;
• and
• (K) a radioactive radiation detector disposed on said catch container with a control monitor connector thereto, said control monitor being adapted to open said third magnetic valve according to the quantity of liquid in said catch container and to close said third magnetic valve in case of a rise of the measured radioactivity of said quantity of liquid in said catch container beyond a certain permissible value.
