On Geiger Counters, Freedom of Information, and Democracy

A few weeks ago I found myself in Washington DC.

I was engaged in activities I think the activist Founders of the USA would deem profoundly American – though the issues are ones they probably could not  imagine in their day.   The event involved democracy, freedom of information, new technologies, and, yes, Geiger Counters.

Since Fukushima Daiichi events, many Americans have been disturbed by the lack of data provided by governments on any radiation impacts.  There have been a lot of problems with the EPA Radnet monitoring system, and people find it confusing.   See Forbes Magazine article on Radnet.  No U.S. agency is charged with monitoring radiological safety of the oceans, or the food that comes from it.   Assurances that everything is okay would be better received if there were data to back it up.

Security around nuclear materials is also a big concern these days.

Many of the individuals involved in the DC event are trusted representatives of well known (and respected), independent, non profit organizations.  There were also representatives from Academia.  And there were US Government Agencies charged with protecting public health, safety and security.

Natural Resources Defense Council  Rooftop, Washington DC – Geiger Counter Workshop Participants

The common interests of these groups revolve around things nuclear:  preventing bad things from happening, and dealing with the problems if/when bad things do happen.  A complete list of organizations represented is contained in this blog post by Bemnet Alamayehu at Natural Resources Defense Council (NRDC)  .   NRDC sponsored the event with support from the John D. and Katherine T. MacArthur Foundation.

The eventʻs outstanding success was due largely to the good reputation NRDC has achieved over many years by working in the public interest on complex environmental and security issues.   The NY Times calls NRDC  “One of the nation’s most powerful environmental groups.”  NRDC has for decades supported the important role of independent citizens in radiation monitoring programs.  In the nuclear arena there is also tremendous goodwill and respect afforded NRDC for their innovation and success in supporting international nuclear safety and arms control programs.   I have personally been a fan, volunteer and a supporter of NRDC for decades.  Earlier work with NRDC took me to Post-Chernobyl Russia and Belarus to support communities in an independent radiation monitoring program – at a time the old USSR (under which it was illegal for citizens to possess a geiger counter) was crumbling .

The form this particular exercise in democracy took, and how it unfolded on this day, would not have been possible without the participation of the good people from Safecast, who designed the system and the instruments we used, facilitated the detector building workshop, and co-facilitated the deployment and mapping exercise, with NRDC.  Safecast developed a technologically advanced system for rapidly compiling radiation data in response to the March 2011 events at Fukushima Daiichi, Japan.  Safecast covered the Washington DC event at this blog post on their website.  I have also been a supporter, volunteer, technology provider and advisor to Safecast since April 2011.

These “Nanos” were built by workshop participants the first day of the workshop.

To get to the point, we basically hand built a lot of the Safecast “Nano”  radiation detectors.  They are uniquely equipped with satellite GPS receivers, specialized sensors, and micro SD card data loggers.  We fanned out around the centers of power and historic sites in the nationʻs capitol, logged radiation levels, and then published the data to the world wide web – all within 32 hours.  The data can now be viewed on the Safecast iPhone App (available free at the Apple Store)   We also installed a real-time radiation monitoring station at NRDC Washington D.C. Headquarters, just a few blocks from the White House.

Could our activities in any way compromise National Security?  I have asked myself that question many times over the years – when I have been asked to become involved in community monitoring projects.  I could not imagine any problems, and have never seen anything but positive impact on communities.  Apparently the Department of Homeland Security and National Nuclear Security Agency agreed.  They sent representatives to observe and participate.

Freedom of Information is a basic tenant of Democracy, and also recognized internationally as a basic human right.  Informed citizenry is considered to be a foundation of strong democracies.  Security is something all communities naturally strive for.  The overwhelming majority of us want our cities, our children, to be safe.

The more radiation detectors and data out there the safer we are, I believe.  If anything unusual surfaces, we all want to know about it – and to feel empowered to take appropriate action.  The good news is that radiation levels around the White House, the US Congress, the Washington Mall all look pretty normal (see color coded map above).  The slightly elevated readings around the World War II Memorial are due to naturally occurring material in the granite monuments.

More events are in the planning stage.   Your city may be next.  Stay tuned.

Update on Surferʻs Beach Radioactivity and a Message from California Office of Emergency Services

Opinions expressed in this article reflect only the authorʻs viewpoint.

Earlier blogposts here identified elevated radiation levels at Surferʻs Beach in Half Moon Bay as “not from Fukushima.”  After a trip to the site and further analysis, I stand by that conclusion.  I will publish more on that here soon.   I hope this alleviates concern across the Pacific Rim, because it should.

Independent Safecast has put together a compilation of information on Fukushima Daiichi impacts on the ocean here.

California State Office of Emergency Services (CalOES) has informed me that California Department of Public Health (CDPH) is doing further testing on samples taken from Half Moon Bay. They will post the results here.

I applaud CDPH for taking a precautionary approach.

I think this is a good idea for a number of reasons.  Most importantly, it will help build trust that this beautiful  beach is a safe place for children.  I have requested further details of the nature of the testing.

I hope that a full chemical and spectral analysis will be done to determine without doubt that these naturally occurring radionuclides are native to this beach and not introduced.

Part of my cautious approach to this is the public knowledge that radioactive materials were dumped at the Farallon Islands, approximately 35 miles offshore from Half Moon Bay.  There are also other sites in the Bay Area  contaminated with TENORM materials, notably Treasure Island and Hunterʻs Point.

Further testing will help build public confidence that California is a place where transparency thrives, where our public officials are proactive in protecting the public health, and where our beaches are safe.  I hope and expect that will be the conclusion, and again thank CDPH for further testing.

CalOES asked me to post this message:

“There is no public health risk at California beaches due to radioactivity related to events at Fukushima . The California Department of Public Health (CDPH) is not aware of any recent activity at Fukushima, or any new data that would cause elevated radioactivity on California shores from the Fukushima incident.  Recent tests by the San Mateo County public health department and CDPH show that elevated levels of radiation at Half Moon Bay are due to naturally occurring materials and not radioactivity associated with the Fukushima incident.

The volume of water in the Pacific Ocean has a significant diluting effect on radionuclides that are present and it is not anticipated that the concentration will increase in the waters off of the west coast. CDPH has collected and will be analyzing sand samples from Half Moon Bay.  Results of the analysis will be posted on the CDPH Radiologic Health (RHB) website (http://www.cdph.ca.gov/programs/Pages/RHB-RadReport.aspx) as soon as the analysis is completed.”

Other information:

CDPH also performs routine air and milk samples as required by California law.  Slightly elevated air and milk samples were found during the initial phases of the Fukushima incident (March 2011) and the results were reported on CDPH RHB’s website (see link above). CDPH continues to monitor air, milk, kelp, and fish samples. CDPH’s monitoring is part of its on-going environmental monitoring program and will be publishing data on the CDPH RHB website by the end of this week.

CDPH has been in contact with the U.S. Nuclear Regulatory Commission (NRC) and they are monitoring the situation with the nuclear reactors in Japan.   The FDA as well as the private entity Woods- Hole Oceanographic Institution (WHOI) have monitored fish from the Pacific and while minute levels of cesium were found in blue fin tuna most recent tests show even those small levels are declining. The United States Environmental Protection Agency (USEPA)  is the coordinating Agency for response to international emergencies involving radioactive materials and the FDA is responsible for food safety.  FDA’s  hotline number is 888-723-3366.  The USEPA, via their RadNet system,  monitors the nation’s air, drinking water, precipitation, and pasteurized milk to determine levels of radiation in the environment. RadNet sample analyses and monitoring results provide baseline data on background levels of radiation in the environment and can detect increased radiation from radiological incidents, such as the Fukushima incident.   You may visit the USEPA RadNet website at http://www.epa.gov/radnet/ and this site has a link regarding public questions.
