monitoring

M. Kaltofen -- Natick, Ma, uSa
Mr. Kaltofen, a professional engineer, is president of Boston Chemical Data Corporation and participates as a technical expert for environmentally regulated activities and in legal actions, having arrived at this work as a natural progression from Project Coordinator for Greenpeace UK and founder and principal at Citizen's Environmental Laboratory that performed services for people, local governments and others impacted by contaminated sites.

Marco's work since Fukushima has displayed a rough-and-ready creativity that has made detection of radiation much easier and less costly and therefore more accessible. The air filter from an automobile offers a very good analog to respiration by lungs--and can be cut open and laid on photographic film for an immediate assessment of levels of "hot particles."

In the 1970's a large network of activists known as the Clamshell Alliance opposed the construction of nuclear power reactors, with a primary focus of nonviolent direct action on the Seabrook site in New Hampshire. In 1986, as the construction of Seabrook 
moved forward, a group known as Citizens Within The 10-Mile Radius formed--and more than 5000 members challenged the evacuation plans for the site. In 1991 Sandy, supported by this strong community, founded C-10 as an ongoing nexus for a citizen monitoring network in Massachusetts and New Hampshire which continues to this day.

D. Sythe -- International Medcom, Sebastapol, CA and one of the Safecast team
A globe trotter with a long history of creative innovation and service to the needs of humankind, Dan is the principle founder of the California-based International Medcom which provides the basic, relatively affordable "RadAlert" and also more sophisticated digital radiation monitors. When Fukushima melted down, Dan was, of course, mobilized to assist people in Japan with the daunting task of acquiring reliable information about radiation levels. There is a very interesting (long) "origin story" for Safecast, but suffice it to say, Dan's hardware genius was taken hand by the digital kings and queens of the planet, and Safecast was born as a way to track radiation levels using sensors on the outside of a car or bike. This campaign has normalized the collection of data on ambient radioactivity to where, at long last, we have a large body of data available that is "apples being compared to apples" not that old "orange" problem.

C. Courbon and B. Chareyron -- CRLLRAD, Valence, France
CRIIRAD, the "Commission for Independent Research and Information about Radiation" led by Christian and Bruno, have organized visits and measurements in areas located in the vicinity of uranium mines in Namibia; Chernobyl and its fallout across Europe; and now Fukushima. This team was one of the first publishing independent evaluations of radiation levels in Fukushima see: http://www.criirad.org/actualites/dossier2011/japon_bis/en_anglais/11-07...
They have an enormous catalog on YouTube, primarily in French, but this item (in English) on detecting radiation in food is a classic: http://www.youtube.com/watch?v=MvBoQfN18zs
