Lennar HQ at HPS is contaminated with nuclear radiation officials and politicians exposed to cancer causing isotopes

City of San Francisco Officials, City Staff, Politicians and their families, why do you think your are immune to radiation? It is not just for poor people, it is an equal opportunity killer and you were exposed.

Lennar builders couldn’t have picked a worse site to locate their site office at Hunters point Shipyard, the Submarine Barracks, the decontamination chamber for the dock workers who sandblasted the radioactive ships from the Atomic Bomb tests in the Pacific.

If you worked for Lennar, or if you were a city official, or staff for the politicians, or a politician, and their families who did photo ops on the shipyard, you will need to watch out for cancer for the rest of your lives. That means telling your doctor that you were needlessly exposed to the products of an Atomic Bomb:

Rear Admiral T. A. Solberg,
Code 180, Bureau of Ships
Navy Department,
Washington. D. C.

Dear Admiral Solberg:

Speedletter serial 1381 of 24 September was received, and all concerned here were highly pleased with its contents.

My trip to Seattle was most beneficial, as I was able to clear up many points. Upon my arrival aboard the USS BAYFIELD, I encountered trouble trying to inspect the evaporators. The evaporator room was locked under orders were issued to the effect that no one was permitted to enter. It seems that Lieutenant Shallow (monitor) issued instructions that the evaporator room was contaminated. The reason for his action was made upon arrival aboard the BAYFIELD, two tube nests were removed from the shelves and the crew had mechanically cleaned them.

REPORT NO. 8 – EXPERIMENTAL WORK AT SAN FRANCISCO NAVAL SHIPYARD
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.

1946-09-16 Submarine Barracks at Hunters Point Shipyard contaminated by use as decontamination centers for workers at Shipyard to clean ships used in atomic tests.

Citation: OPERATION CROSSROADS, RADIOLOGICAL DECONTAMINATION OF TARGET AND NON- TARGET VESSELS Part 2 pp. 14-18

Navy Reports that document the dumping of nuclear waste directly into San Francisco Bay as well as other Navy Bases, the orders, correspondence, etc.

[Submarine Barracks at Hunters Point Shipyard now used as commercial space and was the ironically the site office of Lennar Builders were used for decontamination of shipyard workers who scraped and sandblasted the ships from the Atomic Tests. These buildings were used by the workers to clean off by showering off the plutonium and other radioactive elements and may be some of the most contaminated buildings on the site. The Hot Cell where they stored nuclear materials in lead lined chambers and maybe the storage of radioactive waste all over the shipyard may have more contamination. These are also where the workers ate their lunches while in contaminated uniforms.

Building 103 which still stands and is directly over the fence from the Artists buildings is referenced directly in this report but the decontamination centers soon expanded to all of the submarine barracks as the ranks of the personnel increased.]
