Radioactive substances rose 5 km in air on March 14-15 — Carried by jet stream to US and Europe

VIDEO: US states hit with “extremely large peaks” of Fukushima radioactive material – “Significant amount” of plutonium released for months – Radioactivity from plant “measured globally” and blanketed entire Northern Hemisphere

Study: Global consequences from Fukushima-like nuclear disaster; Many nations at risk of ‘great exposure’ — Transport of hot particles to US was especially effective during worst releases after reactor explosions — Radioactivity confined ‘close to surface’ due to seasonal factors (VIDEO)

Fukushima nuclear material reported in West Coast groundwater; It’s discharging into Pacific Ocean — Fallout also found in meat and fish from same area — “Routinely detected’ in plant life long after March 2011

More quakes hit Fukushima — Official: We ordered workers to evacuate areas after M6.8 hit by nuclear plant — Expert: Typhoon causing increased radioactive runoff into ocean? Storm passed over epicenter of quakes — Another typhoon developing in same area as Neoguri; Japan urged to monitor progress (VIDEO)

MIT Professor & US Experts: Japan “must act now to seal Fukushima reactors, before it’s too late” — Concern US to be affected by “explosions – a chain reaction, engulfing reactors one to four” — “Situation is dynamically degrading and unstable” — Aircraft can likely entomb plant in 6 months

New tests show plutonium reached millions of times normal levels at WIPP site — Concern air filters at plant may not have worked — Gov’t accused of lying about radiation leak (VIDEO)

Professor: Fukushima material to be washing up for years on West Coast — “The fish are going to have some in them” — “People have the right to know what’s there” — “Probably not” enough to worry about

Strange: Sandy to strengthen as it gets cooler; Energy being injected into hurricane — Governor: Storm hasn’t peaked yet

“Never Seen Anything Like This”: Hurricane Sandy begins merging with polar air mass, threatens US East Coast — Over a dozen nuclear plants brace for impacts (VIDEO & MAP)

Nuclear Expert Back From Japan: Fukushima deposited a lot more radioactive material than Chernobyl, except for immediate area around reactors (AUDIO)

All of Western US and most of East Coast, Midwest, Canada covered with airborne particles at various altitudes on March 20, Fukushima plume model shows — Based solely on Reactor No. 1 explosion (PHOTO)

Iodine-131 now detected in Austria, Czech Republic, Hungary… other countries — An indicator of nuclear chain reaction — 10 days after criticality talk at Fukushima

Paper: Group wants radiation tests done in Canada — Health Canada calls 300 times background levels of iodine-131 “minute”

Fox News: “U.S. is receiving a steady flow of radiation from Fukushima” — Media paying little attention to radiation in food, as if problem only involves Japan

Fukushima Weekly Wrapup for June 24

Vancouver, Canada radiation tests show iodine-131 in rainwater at almost 100 times above US drinking water limit

Radiation from Japan reaches B.C. shores, Simon Fraser University Media Release

Radioactive seaweed found in Vancouver, CA — “As of now, the levels we’re seeing are not harmful”: Nuclear physicist

Radiation detected in B.C. seaweed and rainwater not dangerous: researchers, Vancouver Sun, March 28, 2011 at 4:11 pm EDT

TV: Materials floating to North America from Japan could well be radioactive — There’s no monitoring going on (VIDEO)
