The metabolism of curium in the rat by Kenneth Gordon Scott( )

2 editions published in 1948 in English and held by 24 WorldCat member libraries worldwide

The heaviest of the known elements is curium, which was recently discovered by Seaborg and his associates. This new element can be produced by the alpha particle transmutation of plutonium by the following reaction: ₉₄Pu²³⁹ + ₂He⁴ --> ₉₆Cm²⁴² + ₀N¹ This isotope of curium is radioactive and decays by the emission of an alpha particle to form plutonium 238 which, in turn, is also radioactive. Curium 242 has a half-life of 150 days, and its radioactive daughter, plutonium 238, has a half-life of 50 years. This isotope of plutonium decays by the emission of an alpha particle to form uranium 234 which has a half-life of 233,000 years. Shortly after the organization of the Atomic Energy Project, it became apparent that formidable problems would be presented as the result of the release of nuclear energy. One of the most urgent of these was the hazard presented by the production of large quantities of the radio-elements created by the fission of uranium and the coincidental formation of neptunium and plutonium. In an attempt to evaluate the potential danger presented by these radio-elements from the chain reacting pile, a large series of metabolic studies with experimental animals were undertaken in a number of laboratories working upon the Atomic Energy program. These studies, which have been briefly summarized elsewhere, included a series of investigations on the metabolism in the rat of the more important members of the fission products in the carrier-free state, as well as most of the heaviest elements at the end of the periodic table. These studies made it possible to predict on a semi-quantitative basis the potential hazards that this large number of radioactive elements might present should they gain entry into the body
Acceleration of stripped C¹² and C¹³ nuclei in the cyclotron by J. F Miller( )

2 editions published in 1950 in English and held by 22 WorldCat member libraries worldwide

The metabolic properties of the fission products and actinide elements by J. G Hamilton( )

2 editions published in 1949 in English and held by 22 WorldCat member libraries worldwide

An investigation of the assimilation, distribution, retention, an excretion of the fission products and actinide elements in the rat has been conducted at the Crocker Radiation Laboratory, University of California, Berkeley, California. These studies were initiated October 15, 1942, and are continuing at the present time. An extensive survey has been made of the metabolism of twenty-two different radio elements in the rat
Summary of metabolism of carrier-free fission products in the rat by J. G Hamilton( )

The metabolism of americium in the rat( )

Reduction of carbon dioxide in aqueous solutions by ionizing radiation( )

2 editions published in 1951 in English and held by 20 WorldCat member libraries worldwide

The question of the conditions under which living matter originated on the surface of the earth is still a subject limited largely to speculation. The speculation has a greater chance of approaching the truth insofar as it includes and is based upon the ever wider variety of established scientific fact. One of the purposes of the herein reported observation was to add another fact to the ever increasing information which might have any bearing upon this most interesting question. It is not our purpose in the present communication to discuss the various proposals or the arguments which have been adduced for and against them. One of the most popular current conceptions is that life originated in an organic milieu on the surface of the earth, (1,2,3,4,5). The problem to which we are addressed is the origin of that organic milieu in the absence of any life. It appeared to us that one source, if not the only source, of reduced carbon compounds in complex arrangements might be the interaction of various high energy radiations with aqueous solutions of inorganic materials, particularly carbon dioxide, and nitrogenous compounds such as ammonia and nitrogen, since it appears that these compounds were the commoner forms in which the essential elements found themselves on the primordial earth. While it has long been known that high energy radiations can cause organic decomposition and oxidation, it seemed useful to us to demonstrate that conditions could be found in which high energy radiations could induce the reduction with water of carbon dioxide and the ultimate creation of polyatomic molecules (other than simple polymerization of monomers) of carbon, oxygen, hydrogen and nitrogen
Summary of iodine physiology and metabolic studies using radioactive isotopes of iodine by J. G Hamilton( )

Technical progress report on the metabolic studies of fission products by J. G Hamilton( )

3 editions published between 1944 and 1947 in English and held by 20 WorldCat member libraries worldwide

Incomplete tracer studies with product indicate that less than 0.05% of this element is absorbed from the digestive tract in any of the three valence states. The behaviour of plus 4 product following intramuscular and intrapulmonary administration is very similar to that of zirconium. The metabolic properties of plus 3 and plus 6 product are very similar to those of yttrium and plus 3 pre product
