Radiation intensity at center 42 inch riser on waste storage tank (MJ-4)

Description: It is recommended that the actual intensity existing today above the liquid be measured before recommendations are made on cutting through the concrete seal. A detailed statement of work on this problem follows. The calculations have been filed. In the study of the feasibility of cutting through the concrete seal on the center riser of the waste storage tank the radiation intensity that would be encountered is critical because director operator contact would be required. The question of the rad… more

The less familiar elements in the Atomic Energy program

Description: Many factors are responsible for the rapid growth of analytical chemistry during the past ten to fifteen years (This report was written in 1953). One of the most important of these factors is the greatly increased significance to present day chemistry of many elements that in the recent past were principally chemical curiosities. Since the Atomic Energy program is concerned with many such elements, it is of interest to discuss the cause for this concern and the resulting effect on the field of … more

Summary of information for U.K. -- Information request on gamma flux monitor

Description: Summarized herein is the available information on the subject, ``Reactor Gamma Flux Monitors.`` Apparently, a misunderstanding exists between the U.K. representatives and the related information presented by Dr. Nilson at the Argonne meeting July 24 and 25th. Dr. Nilson`s reference at the US/UK meeting was to the use of gamma-compensated neutron detection chambers at Hanford. Such chambers have been designed and used in one old reactor for a short period as a prototype for a detector for the oc… more

Gamma energy analysis of the RMA Line and Recuplex

Description: Knowledge has developed steadily over the past 18 months toward defining the characteristics of the gamma and neutron radiation associated with plutonium and its compounds. Laboratory measurement have been made on plutonium samples taken from the RMA Line, film badge studies have been made in plutonium processing areas, and calculations have been made predicting dose rates and shielding requirements at higher plutonium exposure levels. As these studies continue, and more precise data is accumul… more

DETECTION AND TELEMETERING OF IONIZING RADIATION BY FREQUENCY VARIATION

Description: Three methods are discussed for detecting ionizing radiation and transitting the intelligence. All three methods make use of the reactamce variation of a frequency determining network, to vary the frequency of an R.F. transitter as a function of ionizing radiation entering an ion chamber or counter. The first method is based on the capacitance znd subsequent frequency variation of am electrometer incorporated in an ion chamber. The variation is achieved by a moving came electrometer, where the … more

Production and Decay of the K<Sup>0</Sup> Meson

Description: This paper was previously abstracted irom the original language and appears in NSA Vol. 11, as abstract No. 13429. l9565 Selection rules, which occur ln the annihilation of a found nueleon-antinucleon system were examined. The decay of neutral K mesons with allowance for the conservation of combined parity was also investigated. (auth)

HEALTH PHYSICS ASPECTS OF HANDLING URANIUM-233 FEED MATERIAL

Description: The processes of separation purification and fabrication of feed materials containing U/sup 232/, U/sup 233/, U/sup 234/, U/sup 23 and U/sup 238/ require much closer health physics supervision than do the enriched or naturally occurring mixtures of U/sup 234/, U/sup 235/, and U/sup 238/ found in natural uranium. The primary problem is the control of alpha and gamma radiation. The isotope U/sup 233/ presess only an alpha control problem; however, the daughters of U/sup 232/constitute a gamma pro… more

Ultrasonics for Radioactive Decontamination

Description: Tests have been run to determine in a preliminary fashion whether ultrasonic vibration would be effective in removing mixed radioactive deposits from the inside surface of steel pipes in a heat exchanger. Different frequencies (20 KC/S, l000 KC/S) have been used at the maximum power levels conveniently attainable. Different liquids were compared for cleaning effectiveness, with and without ultrasonics. Mild stirring of water bath at room temperature produced virtually no cleaning effect on the … more

Remote Radiological Monitoring

Description: A gamma-radiation telemetering system was utilized to measure fall-out levels at the Ncvada Test Site. Two methods of signal transmission were used: directcoupled field lines for on-site installations and commercial telephone lines for areas out to 330 miles. Graphic and tabular data cover on-site and off- site residual gamma-radiation dose rate measurements taken as a function of time after selected events. (auth)

A GAMMA-RAY ATTENUATION METHOD FOR VOID FRACTION DETERMINATIONS IN EXPERIMENTAL BOILING HEAT TRANSFER TEST FACILITIES

Description: Gamma rays emanating from a radioactive source are beamed through and are attenuated by steam --water mixtures contained in a simulated reactor flow channel. The emergent radiation is detected by a scintillation crystalphotomultiplier tube assembly. An expression is developed which yields the void fraction when the detector output with the channel empty, filled with water, and containing the mixture in question is known. The principal sources of errors inherent in the method are analyzed and th… more

Final report: Development Test No. 105-609-A: Slug rupture detection experiments at 105-C

Description: This report details the evaluation of the prototype Gamma Monitor system which demonstrated more sensitivity for rupture detection than the C Beta Monitor in agreement with earlier tests at H pile. In one instance a rupture was indicated several hours earlier by the experimental gamma installation.
