Preliminaries Regarding the Monitoring of the Parameters of a Separation Cascade for Isotope 18O

The paper describes the obtaining method for isotope
¹⁸
O, the reactions of isotopic exchange between nitrogen oxides and the aqueous nitric acid. Through these reactions, the isotopes of an element that differs only by the different number of neutrons within the nucleus, change places between two or more molecules. The security of the productive plant and the entire operation personnel requires monitoring on different hierarchical levels. All these justify the need of distance monitoring of its parameters of the two separation stages as well as the under pressure hydrogen supply system.
