July 16th nuclear explosion: Permanent earth displacement

July 16th nuclear explosion: Permanent earth displacement

Date: October 3, 1945
Creator: Reines, F.
Description: A measurement was made of the permanent earth movement in the neighborhood of the tower caused by the nuclear explosion at Trinity. The crater was apparently formed by a compression phenomenon and was noted to be much shallower than craters formed by ordinary high explosives. Scaling up existing information on the radius of craters, the TNT equivalence of the nuclear bomb is given as 10,000 tons to within 50 percent. Observations were made on the damage in the crater region and suggestions are given as to the nature of structure which might be expected to withstand the blast close to the gadget. It is also noted that, despite previous opinion to the contrary, it is apparently possible to reduce greatly the volume of earth blown away by the blast by suitably protecting the ground.

Studies of the hemolytic effect of radiation

Studies of the hemolytic effect of radiation

Date: July 10, 1945
Creator: Schwartz, S.; Katz, E.; Porter, L.M.; Jacobson, L.O. & Watson, C.J.
Description: These studies were aimed at elucidating affects of radiation in inducing hemolysis independent of inhibition of erythropoiesis. Research studies were conducted both on human patients and dogs. Phosphorus-32 in mc amounts were administered either intravenously or orally to patients suffering Polycythemia rubra vera. Dogs were treated with either P-32 or x-radiation. Hemoglobin metabolism was monitored in all test subjects by hematology, blood chemistry, and fecal excretion of hemoglobin catabolites.

A study of the Quartz Fiber Balance No. 1 (Information Report)

A study of the Quartz Fiber Balance No. 1 (Information Report)

Date: August 1, 1945
Creator: Haring, M.M.
Description: This article is a de-classified document produced by Monsanto Chemical Company-Unit III in Dayton, Ohio. The date of the document is August 1, 1945, and the subject is the operation of a quartz fiber microbalance. In particular, the document examines whether temperature fluctuations affect the operation of the instrument. Data was presented to show that the accuracy of the instrument was indeed affected by ambient temperature.

Questions on the toxicity and behavior of product in the body

Questions on the toxicity and behavior of product in the body

Date: December 31, 1945
Creator: English, S.G.
Description: This May 1945 report deals with how best to estimate the toxicity of ``Product`` to workers at Clinton Laboratories. Discussed are the issues of how toxic product is relative to radium, methods of analysis of product in the body, means of elimination from and distribution of product within the body, and what therapeutic measures are available. The principal concern of the author is that of protection of personnel who regularly handle in the laboratory large amounts of this material.
