SECRET

Maxwell: We called this conference together to make certain recommendations to’ BuShips on the means and methods to decontaminate salt water piping based on experiments conducted at this Yard – using ammonium citrate solution and muriatic acid solution. We found that muriatic acid removes all the foreign matter and activity. It does a complete job. The ammonium citrate does a similar job to a lesser extent – about 90% of the activity is removed. We found a medicine that can be used – it may not be the best, etc.

Dr. Scott and Dr. Rodenbaugh, are you in a position to give us a few answers that we are after – when should we use this medicine – what standard should we use – when should we use the acid and when should we use the citrate thru the salt water system?

Rodenbaugh: You mean as to how much radiation you have in the systems? You may ask me from a medical point of view, but ask Dr. Scott about the physical aspects.

[It is important to note that the safe radiation levels at the time did not put into consideration the cancer hazard and all they were concerned about is preventing radiation sickness. All of the sailors involved in this operation were later compensated with a settlement from the United States after Congressional Hearings in the Clinton Administration, the ones still alive of course.]

PART I

DECONTAMINATION OF TARGET VESSELS

1. As a result of Test Able on 1 July, no extensive deposit of long life radioactive fission products or alpha emitters was found on the target vessels. Radioactivity existing was induced type and was of very short half-life. Within a period of twenty four hours after fission of the bomb the level of radioactivity permitted reoccupation of surviving targets, with the exception of concrete barge YO-160, without radiological hazard. Consequently no decontamination of target vessels was required. Continue reading “OPERATION CROSSROADS, RADIOLOGICAL DECONTAMINATION OF TARGET AND NON- TARGET VESSELS Part I”
