Definitions
- the invention relates to a device for the Handling radioactive doped waste water, in particular by radionuclides in medical therapy and Diagnostics, via decay systems with intermediate storage of waste water in collection tanks and finding the approved radioactivity before being discharged into a Sewerage.
- radionuclides that are used metabolic diseases (functional diagnostics) or local defects (localization diagnostics) too diagnose or inflammation or malformation to be able to target therapy.
- the patient applied radionuclides are predominantly based on eliminated naturally.
- JOD-131 is the very low activity concentration of 7 Bq per liter.
- the necessary decay times are usually at least 16 HWZ, ie around 130 days for JOD-131.
- the decay factors have powers of 10 -5 or 10 -6 .
- the object of the invention is to provide a device generic type to improve with little Effort a relatively accurate capture of the content of To enable collection containers in a simple manner and make optimal use of a limited storage capacity, to optimize medical treatment, as well as a Compliance with the specified regulations enable.
- the waste water can be fed to a buffer tank with the interposition of a measuring tank an integrated probe for radioactivity and / or Nuclide determination in a collection tank can be emptied in batches and that the determined Measurement data of an assigned control and computing unit for volume and activity accounting of the Collecting tanks can be fed, in comparison to one set radioactivity after a in advance Calculable cooldown of the collecting tank can be emptied is.
- the measured values are compared to a subsequent one Activity measurement by many before the cooldown ends Orders of magnitude higher, the statistics of stochastic Events radioactivity is significantly better. It there are much greater measuring accuracies and skillful disposition of the chosen collection tanks higher and wastewater and activity throughputs or shorter storage times also achieved.
- An advantageous training is that several Collection tanks are arranged in parallel.
- the arranged in parallel Collection tanks each for different heights Activities and / or different nuclides arranged and can be loaded via the control and computing unit are.
- a favorable training is created in that the buffer tank is designed as part of a vacuum system is.
- the measurement data of Measuring tanks can be fed into the control and computing unit, the radioactivities and / or nuclides of the ingested Wastewater from the collection tank is balanced and after a predetermined decay time via a computer program Derivation after reaching the set values is controllable.
- the feces are considered Waste water from a toilet 30 a buffer tank 1 fed.
- the buffer tank 1 is either as Gravity tank or vacuum tank executed.
- the waste water in a measuring tank 19 transferred to an integrated measuring probe 20 for Has radioactivity determination.
- the corresponding Measured values are sent to a control and computing unit 31 fed and processed.
- the Measuring tank 19 emptied and the waste water is thus a selected collection tank 32 in batches supplied, now the required measurement before Start of storage was carried out.
- the on this Way in the collection tank 32 captured nuclides and Activities are therefore necessary Cooldown over the control and computing unit 31 in calculable in advance.
- the control and computing unit 31 is in accordance with the Preset requirements, and in a known manner becomes a necessary valve and pump control performed.
- valve positions are detected and valve controls carried out according to the program become.
- the entire system is controlled by a PLC control that simplifies handling and management switched on a PC visualization becomes.
- a buffer tank 1 is placed under vacuum.
- An in the circuit switched on ball valve 10 of the Pump line is open as well as with a Check valve 9 provided and the air is over a filter 14 and a heat exchanger 29 for Warming the air to prevent one Pumped off condensate. Possibly nevertheless emerged Condensate is returned to the buffer tank.
- the Pressure conditions in the buffer tank 1 are indicated by a Pressure switch 7 regulated.
- the resulting vacuum is indicated by a manometer 6.
- One in this Measuring line arranged solenoid valve 8 is only for Making an external connection open when the Buffer tank 1 via an open gate valve 11 is pumped out with a sewage pump 3 in total.
- the waste water reaches an open ball valve 4 an inlet 5 in the buffer tank 1, the Gate valve 11 is closed.
- the buffer tank 1 has sensors 15, 16 and 17 for the Level, the sensor 15 being used for the measurement sufficient filling indicates, the sensor 16 the lower Level and sensor 17 reports the overfill.
- the Solenoid valves 24 and 25 for filling in the Connecting lines of the measuring tank 19 opened.
- a metering pump 18 is used, if there is no natural level compensation.
- the valves 24 and 25 closed and via the measuring probe 20 the activity is determined.
- the Measuring container 19 can also with compressed air, which is introduced directly via the valve 22, in the Empty the pipeline to the collecting tank 32.
- the measuring volume of the measuring tank 19 can be smaller than the volume of the entire pipe content up to Collection tank 32, so this may occur measured volume only with the next batch in the Collection tank 32 a.
