摘要： A decontamination system uses magnetic molecules having ferritin cores to selectively remove target contaminant ions from a solution. The magnetic molecules are based upon a ferritin protein structure and have a very small magnetic ferritin core and a selective ion exchange function attached to its surface. Various types of ion exchange functions can be attached to the magnetic molecules, each of which is designed to remove a specific contaminant such as radioactive ions. The ion exchange functions allow the magnetic molecules to selectively absorb the contaminant ions from a solution while being inert to other non-target ions. The magnetic properties of the magnetic molecule allow the magnetic molecules and the absorbed contaminant ions to be removed from solution by magnetic filtration.

摘要： A method for operating the LOMI decontamination process in a regenerative manner. The method incorporates an initial injection of a dilute LOMI solution (vanadous formate, picolinic acid and sodium hydroxide) into a decontamination circuit followed by operation of a small cluster of cation exchange columns during the decontamination process. The cation exchange resin is used to remove metals in the same manner as in prior decontamination processes but operation of the cation exchange resin is continued to allow picolinic acid initially bound to the cation exchange resin to be released and recycled to the LOMI solution. Operation of the cation exchange columns ceases after the picolinic acid has been released but before the metals (e.g. sodium, iron and vanadium) are released back to the LOMI solution. The cluster of cation exchange columns are operated according to a sequence wherein one column is releasing picolinic acid while another is binding picolinic acid. The method further includes continuous additions of vanadous formate and sodium hydroxide. Clean-up at the end of the method proceeds in the normal manner wherein larger cation and anion exchange columns are utilized. Because the concentration of the components is much lower than conventional LOMI processes, however, the amount of cation exchange resin required at this stage is greatly reduced.
摘要翻译：一种以再生方式操作LOMI去污工艺的方法。该方法将稀释的LOMI溶液（甲酸钒酸盐，吡啶甲酸和氢氧化钠）初始注入去污电路，然后在净化过程中操作一小群阳离子交换柱。使用阳离子交换树脂以与先前的去污处理相同的方式除去金属，但继续使阳离子交换树脂的操作使得最初与阳离子交换树脂结合的吡啶甲酸被释放并再循环到LOMI溶液中。在吡啶甲酸释放后，但金属（例如钠，铁和钒）释放回LOMI溶液之前，阳离子交换柱的操作停止。阳离子交换柱的簇根据其中一个塔释放吡啶甲酸而另一个是结合吡啶甲酸的顺序操作。该方法还包括连续加入甲酸铵和氢氧化钠。在方法结束时的清理以正常方式进行，其中使用较大的阳离子和阴离子交换柱。然而，由于组分的浓度远远低于常规的LOMI方法，所以在此阶段所需的阳离子交换树脂的量大大降低。

摘要： A system for decontamination of radioactive components includes an acidic decontamination solution which is exposed to radioactive components to remove a layer of contaminated material and an ion exchange cell which removes the radioactive contamination from the decontamination solution. The ion exchange cell has cathode, anode and central compartments. The decontamination solution flows into the central compartment and the radioactive cations in the solution are drawn towards the cathode. The acidity in the cathode chamber is controlled so that small radioactive metal particles are deposited on the cathode. A cathode solution flows over the cathode which removes the deposited radioactive particles. The cathode solution and small particles flow into a waste collection container where the metal particles settle to the bottom of the container where they are easily separated from the solution. The only waste product produced by the system are the small radioactive metal particles which are easily disposed of. All liquids used in the decontamination process may be recycled.

摘要： An embodiment of a scanning system is described including optical elements that direct an excitation beam at a probe array, detectors that receive reflected intensity data responsive to the excitation beam, where the reflected intensity data is responsive to a focusing distance between an optical element and the probe array, a transport frame that adjusts the focusing distance in a direction with respect to the probe array, an auto-focuser that determines a best plane of focus based upon characteristics of the reflected intensity data of at least two focusing distances where the detectors further receive pixel intensity values based upon detected emissions from a plurality of probe features disposed on the probe array at the best plane of focus, and an image generator that associates each of the pixel intensity values with at least one image pixel position of a probe array based upon one or more position correction values.
