I was about to type up a report on Fairchild Semiconductors in Mountain View using Tritium as a light source for their LCD displays at what is now a Google Quad building on 434 Ellis Street, Mountain View when I came upon this report showing Tritium being delivered to Apple at 19050 Pruneridge Ave Cupertino. 10.5 curies of Tritium which is a radioactive isotope of hydrogen that has a half life of 12.32 Years. This is an invoice for 4-01-2016 to 6-30-2016 and the cover sheet for the invoice is below. Source is Document at Nuclear Regulatory Commission website

Given that the Superfund site is the G. E. Intersil site, this associates it with the San Jose G. E. nuclear reactor assembly plant where they were assembling portable nuclear reactors for the US Army, a project started in the mid 1950s when radiological contamination levels were very relaxed and when they were strengthened in 1959 to 1/3 of what they were before, so all of these reactors were too hot for safe use. The entire program was scrapped by 1965. But this program required a large amount of new electronics and this brought about the beginnings of Silicon Valley.
Unfortunately for the people of San Jose they were dumping waste directly into the sewer system using 1955 standards which are nuclear accidents today. That is the problem with nuclear radiation, the clean up standards of the past, including the most recent past have been less and less radiation so that a site cleaned up 25 years ago is an accident today!
These were portable nuclear reactors that you could put on a truck, a transport plane, a ship or a train and bring it to a military site that had a deep pool with all of the necessary hook ups to set up a nuclear reactor to power the base or for colleges and universities. These reactors had no meaningful shields and were a serious radiological hazard to modern specifications.

There were several other portable nuclear reactor plants in the Bay Area, two I featured in this article Two nuclear reactors sites, 369 Whisman Road Mountainview (now Google) and San Ramon CA where the EPA should also look into assessing the damage to the environment and the people who now live within range of those reactor sites. The 369 Whisman Road reactor site had a high curb surrounding the building to contain the radioactive waste!
The EPA has regulations on conducting radiological surveys for sites and basically everything within 200 feet of a site is considered on the site, that goes for chemical contamination as well as radiological. DTSC has interpreted this to mean the property lines of toxic waste sites but the EPA has different rules. Then there is the distance from the contamination to a quarter of a mile is considered a near neighbor and the distance from a quarter of a mile to a mile is also a near neighbor but with a different set of calculations. The danger is evaluated based on the population near a site so in the case of Apple, this could be a big problem for them. How many people work in their Wheel?
The Federal Law, 40 CFR Appendix A to Part 300 – The Hazard Ranking System which is used to determine if a site is subject to Superfund status, the range of contamination goes out to various distances from the exact contamination site.
It depends on what happened to the Kr 85 which is a Byproduct Material, meaning it came out of a nuclear reactor and cannot be dumped in low level radiation facilities but would have to be disposed of most likely in the Nevada Test Site.
In order to use an isotope like this, the facility would require a hot cell which is a device or room to store radiological isotopes usually with mechanical hands to remove the isotope from the container and use it in whatever industrial process GE was using at the time and the necessary Geiger counter device to measure the Beta radiation from this isotope. It has a half life of 10 years so its still hot. Some hot cells are portable and look like aquariums or those isolated rooms with hands you see in movies or TV shows.
I outline the distances using San Francisco as an example showing the ranges of contamination that can result from Chemical, Biological and Radiological contamination in this article:
“Downtown San Francisco within Contamination Range of Treasure Island Atomic, Biological and Chemical Warfare training sites”
If the radiation was used on a device that has since decomposed in the soil, then you have the larger ranges of water and air contamination that can go out 4 miles from the site.
The Question is, does the EPA know that the isotope was used on the site. Given the other sites in the Bay Area I would give my opinion as to say no, but this will have to be looked into.
If the Nuclear Regulatory Commission had done its job, then there would be a set of inspections and a series of surveys to confirm the radiological isotopes were disposed of property and how they were used.
Google currently occupies the location where American Standard built portable nuclear reactors that were sent overseas in trade shows for the Atomic Energy Commission and for colleges and universities. The AEC shut down the facility because it was located in a densely populated area and given the accidents from these reactors and that the location had no shielding or even containment for the radioactive gasses and radioactive water, it was decided to pull the plug on the reactors. They had two reactors on site and built these reactors for other entities:
Iowa State University
Virginia Polytechnic Institute / North Carolina State college
Australia (Atomic Energy Commission)
Japan (Kinki University) Osaka
Japan (Tokai University)
From the report page 6:
“B. Reactor Building
The reactor will be housed in an existing 20′ x 32′ x 14′ eave height steel frame
reactor building. The building is supported on a reinforced concrete foundation and has corrugated steel walls and roof and a concrete floor sealed with Amercoat. A concrete curb around the base of the building will prevent run off of radioactive water. Gas-tight construction has not been provided. Entry to the building is provided by two sliding doors, which may be locked with a padlock. A stairway provides access to the top of the reactor. A one-ton electric hoist is available for removing the concrete closures from the reactor”
Note the curb around the building to prevent run off of radioactive water and the padlock on the door for security. Remember this is for two nuclear reactors.
This reactor type was based on the Argonne reactor which had some serious defects causing a melt down.Continue reading “Two nuclear reactors sites, 369 Whisman Road Mountainview (now Google) and San Ramon CA”
The project is a redevelopment property within the Teledyne-Spectraphysics (T-S) plume with underlying groundwater probably impacted by the upgradient T-S source properties. The developer plans to construct the building wiht a vapor intrusion mitigation system (VIMS) and water barrier. Indoor air testing will be conducted to verify that the VIMS is working as designed.

The Mora Drive Site was formerly commercial/industrial. It includes several former DTSC sites: PLESSEY #2 (43360131), PLESSEY #3 (43360135), and SYMTRON CORP. (43360124) all of which were determined to require no further action. Lennar conducted sampling in 2015, 2016 and 2017 to confirm that the site has elevated levels of tetrachloroethylene and trichloroethylene in soil gas. Lennar plans to develop the property into residential.
Envirostor State of California Link: “The EPA added this site to the National Priorities List (NPL) in 1991. This Superfund site is comprised of several former Fairchild Semiconductor Corp facilities spanning 56 acres in Mountain View. The Fairchild Semiconductor Corp – Mountain View site is one of three Superfund or NPL sites that are being cleaned up simultaneously. The other two Superfund sites are the Intel – Mountain View site and the Raytheon site. All three sites are located in the Middlefield-Ellis-Whisman (MEW) Study Area and are being addressed collectively as the MEW SIte. Site investigations at several of these facilities during 1981 and 1982 revealed extensive soil and groundwater contamination, primarily VOCs. Soil cleanup by soil vapor extraction, excavation, and aeration has been completed at all the MEW study area sites. Groundwater remediation is ongoing at the MEW Study Area.”
The contaminants which have been detected in soil and groundwater include trichloroethylene (TCE), trichloroethane (TCA), dichloroethylene (DCE) and chloroform.

The Teledyne property is part of a two-property Superfund site along with the adjacent Spectra-Physics property.
The responsible parties (RPs) for the Teledyne/Spectra-Physics site completed a Monitored Natural Attenuation (MNA) study in the off-property area north of and downgradient of the site. The MNA study concluded that natural breakdown of the chlorinated volatile organic compounds of concern is occuring naturally and at the same rate as groundwater extraction. As a result, only a few of the off-property downgradient extraction wells were operating mainly to maintain hydraulic control of the plume. The RPs completed a pilot study to test the feasibility of enhanced reductive dechlorination (ERD) and concluded that ERD is feasible with bioaugmentation of the Shallow Zone.
Within the last five years, the RPs detected elevated source areas at the Teledyne property using high resolution technology and continuously logged and screened ERD injection well boreholes. Implementing a full-scale ERD treatability study, they have been and are currently remediating the property with groundwater-CVOC levels dropping from as much as over 80,000 ug/l to low multiples of MCLs. Several rounds of ERD injections successfully cleaned up most of the Shallow Zone at the Teledyne property and the adjacent Spring Street residential area to drinking water standards and the treatability study was even more successful in the underlying Upper and Lower Intermediate Zones.
An on-property IA VI evaluation at a SpectraPhysics property in 2004 indicated no IA-CVOC contamination above the Regional Water Board’s 2008 ESLs. More recently, the RPs also assertively evaluated potential IA VI in the off-property commercial North Bayshore and residential Spring Street areas to conclude that IA VI is not occurring in most of the commercial area and is occasionally occurring in several homes in the residential area. The RPs installed sub-slab depressurization systems in the impacted on-property commercial buildings and offered the affected residents crawl space fans to address the issue.

“I live across the street from one of Google’s many Mountain View campuses in California. My beloved home – a little farmhouse I bought and moved into with my family in 1975 – now lies above the Middlefield-Ellis-Whisman Superfund Study Area (or MEW Superfund site), an area polluted by 11 Potentially Responsible Parties, well-known, multi-billion-dollar Silicon Valley companies that are possibly to blame “for generating, transporting or disposing of the hazardous waste found at the site”.”
Article explains how a farmer living across the street from Google, where they built stations to remove contaminated groundwater out of the ground and clean it by building silos that mixed the polluted water to air so the vapor could be removed from the water and spread into the neighborhoods.
