Abstract: In May 1950, 350 miles of road was traversed in the vicinity of a torbernite locality in New Jersey. The radioactivity of the area traversed was two to three times above normal, averaging 0.003 percent equivalent uranium. It is estimated that there is 1,000 tons of rock averaging 0.009 percent uranium at the torbernite locality. The presence of this area of above-normal radioactivity suggests that further study is needed in the Piedmont belt and the flanking sediments, which may contain economic deposits of uranium minerals.

From abstract: A deposit of rare-earth minerals in the Scrub Oaks iron mine, Morris County, N. J., was mapped and sampled in 1955. The rare-earth minerals are mainly in coarse-grained magnetite ore and in pegmatite adjacent to it. Discrete bodies of rare-earth-bearing magnetite ore apparently follow the plunge of the main magnetite ore body at the north end of the mine. Radioactivity of the ore containing rare earths is about 0.2 to 0.6 milliroentgens per hour.

Report discussing the U.S. Geological Survey's investigation of uranium occurrences, which were discovered after submission of a sample containing 0.068 percent uranium, at Clinton, New Jersey. Information produced from sampling, mapping and radioactivity testing is included.

The following report covers a reconnaissance for radioactive materials that was made in parts of Maine, New York, New Jersey, and Pennsylvania. It's primary objective was to examine the iron ore deposits and associated rocks in Adirondack Mountains of New York and the Highlands of New Jersey. Additionally, several deposits known or reported to contain radioactive minerals were examined to delimit their extent. However, most of the deposits examined are not significant as possible sources of radioactive elements and the data pertaining to them are summarized in tables provided.

From Abstract: "The primary objective was to examine the iron ore deposits and associated rocks in the Adirondack Mountains of New York and the Highlands of New Jersey."

Report discussing a study in which "a suite of alkalic rocks from the Beemerville, NJ, intrusive body was separated and the percentages of their accessory minerals were determined."

Report discussing an investigation of intrusive igneous rocks for radioactivity in New Jersey, New York, and New England during August and September 1951. This was aimed at finding uranium contents of economic significance in these rocks and determining the geological cause for any radioactivity. Results of the investigation are given by region, and a summary is included.

The following report studies a rare-earth deposit in the Scrub Oaks iron mine, Morris County, New Jersey, that was mapped and sampled in the 1955.

This report describes a summary of information available on substation in New Jersey with their locations,elevations,exposures and many from date station established to 1955.

Chemistry of Feed Materials. Studies were made of the first step in the reduction of UO/sub 3/ to UO/sub 2/. The rates of reduction of pelleted- hydrated and pelleted-dehydrated UO/sub 3/ to U/sub 3/O/sub 8/ in steam were determined. The rates of reduction of pelleted U/sub 3/O/sub 8/ to UO/sub 2/ in 1-to-1 ammonia-steam were determined. Some preliminary measurements were made on the thermal conductivities of hydrated and dehydrated UO/sub 3/ wafers. Purification of Th(NO/sub 3/)/sub 4/ for spectrographic standards is described. Uranium was extracted from MgF/sub 2/ slag with an aqueous solution of sodium carbonate --bicarbonate using 0/sub 2/ at 30 psi as an oxidant. The conversion of thorium benzoate to ThCl/sub 4/ was carried out with HCl in ether. Dimethyl ether was prepared by the catalytic dehydration of methanol. The processing of UO/sub 3/ containing As contamination is described. Metallurgical Investigations. A process for stripping Af and Ni coatings from flat plates is described. Analytical Chemistry. The spectrographic determination of dysprosium and gadolinium in lanthanum oxide matrix--rare earth concentrate is described. (W.L.H.)

Abstract: "The NYX testing of the component disassembly equipment comprised repeated operation of both the quatrefoil disassembly machine and the foil press and shear to evaluate the suitability of these machines to perform their design function with reliability and convenience of operation. During testing, both design and operational deficiencies were found and corrected in the NYX equipment. In general, both machines operated satisfactorily after modification."

From Summary: "To obtain a reliable picture of the anthracite-mine-water problem and to solve that problem, it is necessary to have factual data on the volume and the quality and character of mine water handled by pumping plants in the anthracite region, as well as kinds of pumps utilized and problems concerning their operation. The main conclusion that be drawn from an investigation of drainage practices in the anthracite region is that, although efficient pumping layouts, tunnels for draining active mines, and large-scale surface-drainage facilities for keeping water out of mines are in use, the anthracite industry still is threatened with curtailment, to a major degree, and premature extinction because of the encroachment of water, unless remedial action is undertaken in the vary near future by all interests concerned."

From Abstract: "This report up-dates certain sections of HASL-42, "Environmental Contamination from Weapon Tests". In particular, the levels of Strontium-90 in fallout, milk, tap water, air, and soil are included for data available up to November 1, 1958."

From Abstract: "This report is one of a sequence of quarterly reports, each designed to up-date its predecessor beginning with HASL-42, "Environmental Contamination from Weapon Tests". Herein are presented data which have accrued since HASL-55. Levels of strontinum-90 in fallout, milk, air, water, vegetation, foods, and bone are given, based on data available from February 1, 1959 to May 20, 1959."
