13577 Radiation Film Badges were used at Hunters Point Shipyard in 1960

In 1960 the US Naval Radiological Defense Lab developed 2655 Radiation Measuring Film Badges for Treasure Island and 12,688 for the US Naval Radiological Defense Lab at Hunters Point Shipyard along with 889 for Hunters Point Shipyard separate from the Defense Lab. These badges are dosimeters that measure how much radiation a person was exposed to during a period of time and they were collected from all over the Bay Area to be developed and analyzed at the Defense Lab for the year of 1960.

U.S. Naval Radiological Defense Laboratory., Naval Radiological Defense Laboratory. (1961). Radiological safety at USNRDL: annual progress report health physics division ; 1 January to 31 December 1960. San Francisco, California: U.S. Naval Radiological Defense Laboratory. p 20

This document is a who’s who of radiological exposure just for one year at the US Navy’s Radiological Defense Laboratory and I highly recommend it as reading material to give you a look into the radiation experiments they conducted on the shipyard (including building numbers) and all throughout the Bay Area, including downtown San Francisco!

The presence of radiation badges means each time a human being was exposed to radiation over the course of an experiment or regular monitoring of radiation exposure on site. A very frequent and robust radiological contaminations were taking place at the Shipyard and Treasure Island in 1960.

Camp Parks in Dublin CA was the field station for the Lab where they conducted radiological tests on the base while military personnel worked and lived on the base. These experiments included using the gymnasium to rain down radioactive isotopes to determine its effects on roof structures and that gymnasium was then “cleaned up” and was used by the Navy and then the Air Force when they took over the base and as recently as last year by private entities before it was torn down. Stanford Research did a lot of radiological work at Camp Parks and it is clear they had many nuclear accidents reported in this report from 1960.

Immediate use of a synthetic detergent-sequestrant mixture has been reported to give better decontamination than if the use of the mixture is preceded by soap and water wash. However, no temperature was given for the water used and if the water was warm enough to cause the pores to open, the decontamination solution, normally used cold, would have a difficult time removing the activity.

Dublin California Radiation Experiments at Camp Parks

 

Camp Parks is a Air Force Base that was previously a Navy Base used for radiation experiments in the late 50’s to mid 60’s where they purposely spread radioactive materials onto streets, yards and buildings in order to figure out how to clean up after a nuclear blast. The Navy created dirty bomb incidents all over the Bay Area and trained military personnel from all branches to clean up after a nuclear blast to remove the radiation by scrubbing, firehosing or with street sweepers etc. In the early days, the late 1940’s they thought that fallout was not dangerous, it was not until Operation Castle in 1954 when radioactive fallout fell onto Enewetak Atoll where US military personnel were stationed as well as natives and they got radiation burned from the fallout.

Camp Parks Cobalt 60 Experiments
Camp Parks was used for many radiation experiments Which I will list above when I get the articles up on the site. Fortunately in Complex III tests they decided to limit the amount of radiation they spread onto the grounds, the roads and buildings to .1R per hour which today is a nuclear accident in a nuclear power plant.

Later it would dawn on the Navy that they could use a d
ifferent colored sand and then just count the grains to figure out the amount of fallout. Continue reading “Dublin California Radiation Experiments at Camp Parks”

Work on Monday, 23 September 1946:

USS BENEVOLENCE: Setting up of an acid mixing tank on the main deck ana the hookup Of the evaporators so that all six effects will be completely filled with circulating acid was accomplished during the day. The tank was set up on the main deck to simplify operations and keep the evaporator room from getting cluttered up with acid barrels, etc. Where the Yard felt it necessary, sections of piping removed from the evaporators were kept and new pipes substituted. “Hot*’ valves were dipped in a two normal solution of Hydrochloric Acid on the main deck. The valves showed some radioactivity after ten to twenty minutes of such treatment but were declared safe for work by X31 provided there was sufficient ventilation for anyone working on them.

SIXTH REPORT

6th Report, 20 September 1946 – INVESTIGATION OF RADIOACTIVITY of Vessels from Bikini at the San Francisco Naval

Shipyard begun on 5 September 1946.

Work was begun yesterday to implement the decisions of the medical “strategy” board convened aboard the USS BENEVOLENCE on the 18th.

In advance of one of the measures decided upon (flushing with fresh water of the Salt Water Systems of the BENEVOLENCE and HENRICO) a careful check was being made of the Salt Water Lines to insure that proper isolation of sections being worked on at present would exist, and as a corollary, to obtain a maximum flushing effect with only portions of the felt Water system available. All Salt Water pumps were ordered inoperable (i.e. electric pumps are to be disconnected, steam driven pumps to have valves locked).

The decision to conduct a burning test on sections of hot Firemain piping containing considerable marine growth (a top priority job) was implemented yesterday by the selection of sections of pipe from the LAFFEY and BOTTINEAU (Copper-nickel and steel respectively). Dr. Chadbourn, after monitoring the piping, selected the Shipfitters Shop aboard the LAFFEY for the test, and took samples while the burning was being done, RBA equipment was used by the burner and Dr. Chadbourn.

The, senior monitor, Lt. Comdr. Skow, took readings on all three evaporators of the BENEVOLENCE in preparation for the injection of Hydrochloric Acid (1 normal) which will be started this morning. The evaporator room, because of its difficulty of access, for pumps, acid barrels etc. has required considerable effort to prepare. The readings of the evaporator scale are now said to be 5 times tolerance (and hence exposure should not exceed 4-1/2 hours) not 2 times as stated in the fifth report.

BENEVOLENCE crew men who on the evening of 18 September brushed the scale from the evaporators were warned by Dr. Skow to take longer on similar jobs in the future, as due to their haste large amounts of highly active scale were deposited on piping and floor plates beneath the evaporators. Dr. Skow monitored the crew members yesterday afternoon to determine if they had acquired any radioactivity in their shoes, clothing, under fingernails etc. No activity was found.

FIFTH REPORT.
5th. Report, INVESTIGATION OF RADIOACTIVITY of Vessels from Bikini at the San Francisco Naval Shipyard begun 5 September 1946.

Progress and further developments In the experiments described in previous reports:

Flashing (with fresh water) of the Firemain section on the LAFFEY which had been treated with pH 6 solution continued through the night of 17 September and was secured early in the morning of the 16th. The blanked off ends were opened up and drippings were collected and put in an add barrel. Photographs were taken of the end sections of the piping, showing the work of the solution in removing marine growth. The results can be summed up by saying that the pH 6 solution was not particularly effective ta removing marine growth, although it is estimated that 90% of the radioactivity was removed.

The second phase of acid circulation in the Firemain forward on the LAFFEY was stepped at 0205 Wednesday, 18 September. Flushing was begun at 0215 and at 0300 the line, contain lug-fresh water, was secured. Samples of acid concentration were taken at intervals and a small reduction at .30 occurred. (1.08 to .79) It is estimated that the acid treatment removed 100% of marine growth and scale, and reduced radioactivity about 98%. Precise figures on the decrease in radioactivity of the acid solution between the first phase and the second phase as well as the monitoring of the piping after the decontaminating solution had been removed are contained in a report by the monitor, Dr. Chadbourn, to Capt. Walsh (MC) who is in charge of the experiments. Continue reading “5th. Report, INVESTIGATION OF RADIOACTIVITY of Vessels from Bikini at the San Francisco Naval Shipyard begun 5 September 1946.”

4th Report

18 September 1946

INVESTIGATION OF RADIOACTIVITY Of Vessels from Bikini At the San Francisco Naval Shipyard
Begun on 5 September 1946

Yesterday morning aboard the LAFFEY one experiment in decontaminating salt water piping was concluded and another begun.  The experiment just concluded awaits laboratory testing before any results are known.

The section of Firemain which had been pumped full of pH 6.0 solution (Acetic Acid and Ammonium Hydroxide) on Saturday, 14 September at 1100, was blown out at 1100 yesterday. An air hose was attached to one end of the Firemain and a hose led from the other end to a steel barrel up on the main deck, and the Firemain was blown clear. The contents of the barrel were monitored and showed radioactive emission as heavy as had previously been found in the Firemain on Saturday (.010) which would appear to indicate that the decontaminating solution had brought a considerable portion of the radioactive particles out with it. The barrel of radioactive solution was hoisted overboard, using a quaywall crane, onto a truck and when taken to the Industrial laboratory to be held there until arrangements are made for disposal. One quart of the solution was taken by Dr. Scott for a laboratory assay. After the Firemain had been blown clear of the solution, the air service was disconnected and a fresh water hose connected to the Firemain. The hose at the outlet end was led to a second barrel for examination of the first amount of flushing water. This water was found to be practically free of emission, so on the advice of Dr. Scott the discharge hose was led into the bay and flushing operations were scheduled to continue overnight. The flushing operation was begun at 1330. The leading man of X-56 who was holding the hose in the barrel when the radioactive solution was being blown from the firemain received spray and some of the liquid on his bare hands. He was advised to wash it off immediately.

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?
