- At 0:45 in – Arnie Gundersen, Chief Engineer at Fairewinds Energy Education: If Fairewinds Energy Education was a Japanese website, the State Secrets Law would likely prevent us from issuing this video.
- At 1:15 in — Marco Kaltofen, Civil Engineer & Ph.D. Candidate at Worcester Polytechnic Institute (WPI): In looking at indoor environments, they tend to be much more contaminated than the surroundings outside. Houses act like a trap and they tend to collect outdoor contaminants and they expose people as much as 24 hours a day.
- At 9:15 in – Kaltofen: The sample that we got came from Nagoya in Japan, its 460 kilometers from the accident site. That’s about 300 miles away.
- At 9:30 in — Kaltofen: It’s actually in the size range of dusts that can be inhaled and then retained in the lungs. This is important because if your health physicist and calculating and you’re calculating the dose that you would get from this particle you’d have to consider that this particle might actually be trapped and result in a lifetime exposure.

Hot Particle Detected 400 Km From Fukushima With Over 40 BILLION Bq/Kg
– Hot particle found 400 kilometers from Fukushima with radioactivity over 40 billion Bq/kg — Large black puddles of fallout along roadsides might well be from inside failed fuel rods (VIDEOS) (ENENews, Dec 17, 2013):
Arnie Gundersen, Chief Engineer at Fairewinds, Dec. 16, 2013 (at 3:30 in): Large puddles of black particles have been found on the side of the road, each individual grain is extraordinarily radioactive. This is fall-out, this is hot particles that have coalesced together on the side of the road. Recently a hot particle was discovered 250 miles [400 kilometers] away from Fukushima. It was so radioactive that if it were a pound of material instead of just a particle, the pound would be giving off 20 billion disintegrations per second [44 billion becquerels per kilogram] […] That small speck could easily be lodged in someone’s lung. >> Watch the video here

Japan’s Deadly Radioactive Black Dust – Fairewinds Interview With Scientist Marco Kaltofen (Video & Transcript)
– Japan’s Black Dust, with Marco Kaltofen (Fairewinds, July 10, 2013):
About This Podcast
This week Fairewinds Energy Education interviewed Marco Kaltofen, a leading scientist who studies radiation as well as specific radioactive isotopes. Marco and Arnie discuss a recent sample that contained highly concentrated radioactive material from Japan’s Fukushima Daiichi nuclear power plant accident. As the sound quality of this recording varies, we have transcribed the podcast so you can read along.

About this video
Marco Kaltofen, PE explains how citizens scientists can properly, collect, document, package and ship radiation samples. In this video, he also demonstrates how he analyzes radioactive samples in his lab.
Hot Particles And Measurement Of Radioactivity (Fairewinds Video)
Fairewinds’ Chief Engineer Arnie Gundersen and Boston Chemical Data Corporation’s Founder Marco Kaltofen have an in-depth conversation regarding the challenges of measuring radiation exposures to people around the globe. Kaltofen explains the scientific methodology involved in accurately analyzing and measuring radioactive releases from Fukushima Daiichi, including the impact of hot particles on human physiology.

Laboratory Test Results: Tokyo Soil Samples
Arnie Gundersen: Hi, I am Arnie Gundersen from Fairewinds. This is the first video on the new Fairewinds site. We worked really hard to make it user friendly and searchable and we hope you like it. If you have any questions, please send us a comment.
You recall Marco Kaltofen. He presented at the American Public Health Association a couple of months ago and we heard his presentation. Today, I had a longer conversation with Mr. Kaltofen. Mr. Kaltofen runs the Boston Chemical Data Corporation and he is a professional engineer. He talks about radiation in the environment and especially radiation from the Fukushima accident. I hope you enjoy the conversation between Mr. Kaltofen and me.

Study: Rocky Flats Wildlife Refuge Still As Contaminated With PLUTONIUM As 40 Years Ago
More from Marco Kalthofen:
– Study: Rocky Flats area still as contaminated with plutonium as 40 years ago (Daily Camera, Feb. 18, 2012):
Boulder’s Rocky Mountain Peace and Justice Center hires contractor to test soil for plutonium
Driven by concerns that running the Jefferson Parkway across a strip of land along the eastern edge of the Rocky Flats Wildlife Refuge would stir up clouds of plutonium-laden dust, Boulder’s Rocky Mountain Peace and Justice Center commissioned a study last fall to gauge contamination levels in the area.
The newly released results show the area is as contaminated by radioactive plutonium now as it was 40 years ago, before the Rocky Flats nuclear weapons plant, which operated on that site, was closed and cleaned up.
“The material is still there; it’s still on the surface,” said Marco Kaltofen, president of Boston Chemical Data Corp., the contractor hired by the Rocky Mountain Peace and Justice Center.
