Physicians: ‘Interesting fact’ for West Coast in new UN report, 95% of Fukushima discharges transported in Pacific; Contamination to impact N. America with ‘uncertain consequences’ for public health — Chemist: Concern over recent releases, “They’re changing in character”
Physicians for Social Responsibility, IPPNW, etc., Oct. 18, 2013: An interesting fact for people living on the US west coast is also included in the UNSCEAR report: only about 5% of the directly discharged radiation was deposited within a radius of 80 km from the Fukushima Dai-ichi nuclear power station. The rest was distributed in the Pacific Ocean. 3-D simulations have been carried out for the Pacific basin, showing that within 5–6 years, the emissions would reach the North American coastline, with uncertain consequences for food safety and health of the local population.

Fukushima Radiation Traced in Pacific Seafood […]
Ken Buesseler, senior marine chemist at Woods Hole Oceanographic Institution: That radiation will get across the Pacific […]
Henry Ridgwell, VoA reporter: Buesseler says a bigger concern is the accumulation of isotopes in marine life. Earlier this year, cesium isotopes from Fukushima were found in tuna caught off California.
Buesseler: The tuna that were caught off San Diego with the Fukushima cesium isotopes, they were 10 to 20 times lower than they had been off Japan. Now the new releases, the leak from the tanks, they’re changing in character. Strontium-90 has become of more concern because it’s a bone-seeking isotope. That will stay in fish much longer.
