AB  - The paper considers the application of nuclear magnetic resonance for measurement of fluid-flow. The paper is of an experimental nature. Flowmeter based on nuclear magnetic resonance is extremely precise. The combined measurement uncertainty can be 0.1 %. Such a value of measurement uncertainty indicates that it is a matter of a deterministic and not of a stochastic quantity. This high degree of reliability of the method is theoretically and mathematically described. The paper presents a measurement scheme for flow measurement. Water flow measurement was performed on the principle of nuclear magnetic resonance and on the basis of tritiated water (which is considered to be the most accurate classical method). The obtained results show that the measurement of flow based on nuclear magnetic resonance is more accurate (especially at higher flow). This is explained by the higher inertial mass of HTO tritiated water molecules than the standard H2 O mass and the possible transition of tritiated water to H3HeO. In this way, it has been proven that tracing water based on nuclear magnetic resonance is the only real tracing of water by water. The obtained results show that tracing water with tritiated or heavy water is not tracing water by water which is explained by different inertial masses.

AB  - Quantum mechanics consideration, supported by a concrete example, yielded standard sources of di rect volt age mea sured by frequency (which is the most ac cu rate measur able phys-ical quantity) and extremely sensitive instrument for measuring magnetic induction SQUID (which is an ac ro nym based on the term Supercon duct ing Quan tum Inter fer ence Device). The pos sibility of these mea sure ments is based on the Josephson junc tion. In this paper, the in flu ence of gamma ra diation on the mea sure ment un cer tainty Type A, of a com mercial Josephson compound, is investi gated. The conclu sion is that both dy namic gamma radiation and the dose of gamma ra di ation, un der the con ditions of the ex per iment, have a neg ligible ef-fect on the mea sure ment uncer tainty of the Josephson junc tion. Based on the ob tained re sult, it was con cluded that in the primary metrological con di tions, the mea sure ment un cer tainty type A of the Josephson junc tion is neg ligible, i. e., that the secondary cosmic radiation does not af fect the stan dard of the DC volt age source. © 2021, Vinca Inst Nuclear Sci.

AB  - In nuclear physics experiments, it is very important to isolate the measured quantities from electromagnetic noise. Without this possibility, it is impossible to obtain usable experimental results since natural electromagnetic noise can be several orders of magnitude larger than the measured magnitude. In order to enable such measurements, it is necessary to eliminate electromagnetic noise from the experimental procedure. This is achieved by shielding against electromagnetic radiation. In this paper, experiments were performed to protect a room from electromagnetic noise. By applying all known methods of shielding against electromagnetic radiation, it was concluded that the room can be protected from the electrical component, but it is impossible to protect it from the magnetic component of electromagnetic radiation.
