The Hematological Effects of Ionizing Radiations

Description: This report follows the hematological studies conducted on the Plutonium Project. The studies focus on the internal and external effects of plutonium radiation on biological features, applying these effects toward the protection of individuals who worked in the Project, and using the findings generally for the protection of the public which was potentially in danger of exposure to these physical hazards.

''Cutie Pie,'' A portable radiation instrument

Description: A portable beta and gamma radiation meter of exceedingly small dimensions and weight has been developed. User acceptance has been more enthusiastic than any previous instrument of its type. The circuit, using one Victoreen V-32 tube, is the simplest electronic circuit possible for radiation work and gives high sensitivity. Stability exceeds anything of comparable sensitivity which has come to our attention. The short term stability is due to a circuit which prevents emission before the cathode … more

Effect of single dose x-ray to the nail fold area of human subjects

Description: In order to further understand the nature of changes which occur in the fingers of persons occupationally exposed to radiation a series of experiments were performed on human subjects generally using x-rays at 130 KV potential, 20 ma and at a distance of 10 cm. Doses ranged from 200-600 r. Fourteen subjects were patients being treated by x-rays or radium for other purposes. The other subject was a staff member who occasionally prepared radium plaques containing 130 mgm of radium. Counts were ma… more

A study of the hands of radiologists

Description: A group of radiologists were studied for evidences of radiation damage to the skin of their hands. The technics used were the same as those used for routine hand studies of Argonne National Laboratory personnel and consist of examination of wax impressions of the finger ridges and examination of photographs of the vessels and Papillae in the nail fold. Of the 323 radiologists examined by the first method 48% were found to have ridge abnormalities. The incidence of abnormality increased with yea… more

Blood changes in humans following total body irradiation

Description: A major problem encountered in the Manhattan Project was the protection of workers against damage resulting from acute or chronic exposure to external radiation. The problem of how to detect evidence of damage following exposure to total body radiation led to this study. These studies were conducted between January, 1942 and November, 1945. Three groups of persons were employed in this study. The first group of eight individuals harboring incurable neoplasms which was not extensive enough to in… more

Preliminary Investigation of Effects of Gamma Radiation on Age-Hardening Rate of an Aluminum-Copper Alloy

Description: "A preliminary investigation was made to determine the effects of gamma radiation on the age-hardening rate of an aluminum-copper alloy at temperatures of 32 and 70 degrees Fahrenheit. The gamma radiation from a 100-milligram radium source appeared to have no significant effect on the age-hardening rate of the alloy. A metallographic examination of the test specimens showed no microstructural changes that could be attributed to gamma radiation" (p. 1).

Preliminary Investigation of Effects of Alpha-Particle Bombardment on the Creep Rate of Aluminum

Description: Memorandum presenting a preliminary investigation to determine the effects of alpha-particle bombardment on the creep rate of aluminum wire at 400 degrees Fahrenheit. The alpha radiation from an 85-millicurie polonium source appeared to decrease slightly the creep rate of the aluminum.

Biochemical studies relating to the effects of radiation and metals

Description: Various biochemical effects of radiation have been studied in 10 patients given total body x-ray in total doses of 75 to 310 r (skin), in 5 patients given 20 to 36 mc. P{sup 32}, and in 5 project personnel accidentally exposed to excessive doses of external radiations. Similar studies have also been made of several hundred Plutonium Project personnel exposed in most instances to relatively small amounts of uranium, lead and other metals, and to chemicals and radioactive sources. These studies i… more

Process Monitor Analysis Victoreen Model 350

Description: Abstract: An analysis of the improved Model Number 350 Process Monitor was made so that it could be determined if this instrument would fulfill the need for gamma radiation detection instruments in the production buildings of Y-12. The results of these tests indicated the possibility of marked improvement in the monitor characteristics with minor redesigns. After these improvements have been made, this instrument will be a satisfactory monitor for this area.

Effects of Total Body Z Irradiation of Rats. Part I, Lethal Action of Single, Paired, and Periodic Doses

Description: Abstract: Exposure of Sprague Dawley white rats to single doses of 900 kvp X radiation demonstrated a medium lethal dose of 600 r which was not markedly dependent upon sex, weight, or, in the case of females, stage of the estrous cycle at the time of irradiation. Deaths within 30 days were most frequent between the fourth and eighth, and between the tenth and fifteenth post- irradiation days, indicating the existence of at least two processes leading to death in the "acute" period.

Physiological Observations on Rabbits Exposed to Single Doses of X-Rays

Description: Abstract: Most of the acute deaths among rabbits after single total-body x radiation occur in the first two days or at 10-15 days after irradiation. Signs of clinical depression are seen in survivors of sub lethal doses during each of these periods, termed the initial shock period and the principal acute radiation period.
