USNRDL-TR-256 PROTECTING AND CLEANING HANDS CONTAMINATED BY SYNTHETIC FALLOUT UNDER FIELD CONDITIONS

Purposely contaminating hands to see what damage it would do and to figure out how to protect hands during radiation tests. Also this shows how they lay out radiation tests with the names of the mailing lists. At the time of publication this was secret information so they kept track of who got which report. Note “* number” is the citation number. La140 is Lanthanum 140 a radioactive isotope which is a daughter product of Barium 140 and due to its use this means that at Camp Stoneman had a hot cell on hand to mix the radioactive materials into the sand so workers deposited the radiation using lawn fertilizer spreaders onto roofs, yards and roads in what is now modern day Pittsburg California.

This article is the result of the staff being contaminated by spreading radioactive materials all over buildings, streets and roads of what is present day Pittsburg California and was the second Camp Stoneman radiation test published in 1958. Previous studies had been conducted using more damaging long lasting radiological isotopes and they wanted to make sure that they were cleaning up with sufficient means to protect themselves from the radiation.

ABSTRACT Hands of field test personnel became radioactively con- taminated with (a) dust slurry synthetic fallouts containing La140 tracer, and (b) La140 in acid solution. Two protective creams and several cleaning materials were used in an attempt to reduce adherance of contaminant and to facilitate decontamination. The protective creams were not found to be advantageous. Three experimental cleaning solutions (isotonic neutral solution of a complexing agent plus a detergent and germicide; an isotonic saline solution at pH 2.0 plus detergent and germicide; and a 3% citric acid solution) were found to decontaminate skin more readily than soap and water. A waterless mechanic’s hand cleaner was found to clean hands with the same effectiveness as soap and water.

Pittsburg California Radiation Experiments covering half of the City

Spreading 10,000 rads of radiation onto the ground, roofs and lawns and how they cleaned it up. Note that the exposure to the personnel is only for the theoretical amount that future people would be exposed to while in this case, they were using lawn spreaders to put down 1000 and 10,000 rads of radiation. They also thought that these people were standing on clean ground, extending the brushes onto the contaminated ground. What happened to the people depicted in these photographs?

This article supplements my article with photographs and report text. “Pittsburg California Radiation Experiments, spreading radioactive sand onto barracks, lawns and streets of the former Camp Stoneman Base to train Sailors how to clean up after an atomic strike.”

Pittsburg California Radiation Experiments, spreading radioactive sand onto barracks, lawns and streets of the former Camp Stoneman Base to train Sailors how to clean up after an atomic strike.

This article will be added onto as I post the supporting links. It is a huge story explaining how they spread radioactive contaminant how they mixed it using radioactive materials to create a situation where the radiation levels were at 10,000 rads per hour to simulate the effect of one hour after a nuclear blast.

The problem here, is that the radiation levels were set artificially to be extremely high requiring crews to shift every few minutes in order to clean up the site but if you look at the maps, the areas involved are enormous. So the number of crews necessary to clean the site are in the hundreds. These tests were national events encompassing military personnel from many different services.

North Hollywood High School Nuclear Radiation Test to see how far gamma rays penetrates a school which is still in use to this day!

EXPERIMENTAL EVALUATION OF THE FALLOUT-RADIATION PROTECTION PROVIDED BY SELECTED STRUCTURES IN THE LOS ANGELES AREA February 26, 1963

“An experimental study designed to provide a basis for estimating protection against fallout
radiation was conducted on four diversified structures in the Los Angeles, Calif., area. This
study was sponsored by the Civil Effects Test Operations (CETO), Division of Biology and
Medicine, U. S. Atomic Energy Commission. The four buildings studied were (1) the Laboratory of Nuclear Medicine and Radiation Biology at the University of California at Los Angeles
(UCLA); (2) a family fallout shelter; (3) the communications section of the Los Angeles Police
Department building; and (4) a typical classroom located at North Hollywood High School.

A fallout radiation field was simulated by the Mobile Radiological Measuring Unit. The
unit employed a single radioactive Co 60 source, which was pumped at a uniform speed through
a long length of tubing evenly distributed over the area of interest. Measurements of the radiation levels at selected points inside the structures were made with highly sensitive ionization chamber detectors. Protection factors ranged from 10 to 2000 in the UCLA building, up to 10,000 in the family fallout shelter, from 50 to 150 in the communications section of the police
building, and from less than 10 to approximately 20 in the high school classroom.”

Editors note: Here is an example of a crime against Humanity.

Here are a bunch of enthusiastic trusting people allowing themselves to be needlessly exposed to gamma radiation from this device that was used to spread the radiation by having a capsule of Cobalt 60 in a large length of firehose with 120 gallons of water pushing the radioactive capsule through the firehose. Later in their work, they used an antifreeze solution in order to make it work better. They would dump the antifreeze directly into sewers when they were done. I do not know if they used the antifreeze solution in this test.

It is stretched out on the lawn of the Ambassador Hotel in Los Angeles and they had geiger counters to show the radiation emitted from this location. The radiation produced could range from 100 mc to 300 curies of radiation.

This method of irradiation was much more civilized than mixing the isotopes in a portable cement mixer with sand to spread it over buildings, lawns, and streets by using either a lawn spreader like you have to spread fertilizer on your lawns or a machine that spread it over large areas such as San Bruno Naval Base, Camp Stoneman in Pittsburg California, Camp Parks in Dublin California and a Fort Belvoir in Fairfax county Virginia where they used Strontium 90 to conduct their tests to 30,000 Roentgen of radiation making sure that at the edge of the facility the radiation level was only 2000 Roentgens. 30,000 Roentgens is the amount of radiation at Ground Zero after 1 hour of an Atomic bomb blast. 1 Roentgen = 1 rad but Roentgens measure how much radiation is absorbed by the body so it is far more accurate.

In the mid 60’s someone at the Atomic Energy Commission and the Navy realized that hey you know we don’t have to spread radioactive substances onto buildings, streets and yards, we can just use a different colored sand and then count the sand grains instead of causing cancer on the local population.

These sites are NOT on the EPA superfund lists.
