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.
