Calibration of G.M. Counters For Direct Counting of Radon in the Atmosphere

Description: An experiment has been carried out for the direct calibration of a Geiger-counter immersed in a balloon containing a known concentration of radon in equilibrium with its daughters. A theory was developed for finding out the geometrical efficiency of the counter used in this way, and for checking the experimental results with theoretical efficiency. The counters calibrated in this way may be useful for the direct measurement of radon in uranium mines and may also be useful for monitoring radioac… more

Seasonal Variations of Cesium-137 In The Ground Level Air

Description: An increase in the cesium-137 content of the ground level air has been observed at Bombay during the spring seasons of the years 1957 to 1960. and a similar increase has been observed at seven other stations in India during 1960. The ratio of cesium-137 to gross beta activity have also been studied.

Cesium-137 and Strontium-90 in Milk

Description: Cesium-137 and strontium-90 levels in liquid milk samples from Bombay and 27 other stations in India, and powder milk samples from Australia, Denmark, Holland, India, U.K. and U.S.A/ have been estimated. The results of these measurements have been interpreted on the basis of the total injection of these isotopes in the atmosphere, their rate of fallout, and seasonal effects.

Local Fields With Terminating Expansions (x)

Description: "The quantum theory problem of constructing explicitly a local Lorentz invariant model field theory which has an asymptotic particle interpretation and gives rise to an S matrix different from unity is discussed. It is proved that if a local covariant field H(x) has a complete current, the S matrix associated with this field is identically equal to unity. Results show that in order to get an interaction, the current is not allowed to have a terminating expansion in terms of a free field. The ab… more

Remark on the Radiative Muon Decay in the Theory With an Intermediate Vector Meson

Description: "The problem of explaining the lack of radiative muon decay in an intermediate charged vector meson theory is discussed. A possible way of introducing the charged vector meson to the theory of weak interactions is outlined in which renormalization is retained. However, if this way is used, the anomalous magnetic moment is calculated to be large, which is in contradiction with expectation."

Investigations of Radioactive Fuel-Bearing Glasses

Description: "A series of glass compositions containing uranium oxide was investigated to determine fiberizability and physical properties of resultant fibers. The basic properties to be determined were the maximum U/sub 3/O/sub 8/ content in a fiberizable glass and the maximum service temperature of the fibers. Glasses containing 60 wt% U/sub 3/O/sib 8/ were fiberizable; the fibers had strengths of 100,000 psi at 1600 deg F. Fiber-forming equipment was installed at Moun Laboratory to produce glass fibers c… more

Fluoroscopic Crystal Investigation

Description: "An investigation was carried out on the possibility of increasing the light output of single crystals by applying an electric field throughout the crystal lattice. Pulses of frequency 2.5 x 10/sup 5/ cps were used with a voltage gradient of 10/sup 4/ volts/cm, and gamma radiation from Cs/sup 1//sup 3// sup 7/ and Co/sup 6//sup 0/ was used to excite the crystals. Tests were run on many types of scintillators. The visible light output was found to be increased by electric pulses for many of the … more
