This shows the readings of the global monitoring stations of CTBTO, copied from “Survey of Man-made Radionuclides in the Atmosphere using IMS by CTBTO,” a report by Chusiro Yonezawa and Yoichiro Yamamoto.
Here are main monitoring posts indicated on a CTBTO map. Radionuclides originated from Fukushima were detected all over the northern hemisphere.
This is a screen shot taken from “Global deposition of Cs-137 radionuclides from the Fukushima nuclear power plant accident.” by CYI VISLAB of the Cyprus Institute. To make it easy to see, colors were adjusted.
About 70 days after the accident:
This simulation result matches the fact that the reading in Florida was about the same as the West Coast in CTBTO’s survey.
In North America, some health problems are reported to be linked to the contamination.
Birth defect deaths in West Coast state hit record levels during 2011 － Spiked 60% statewide, then returned to normal in 2012 － New gov’t document lists ‘Fukushima release along west coast of US’ as possible factor in birth defect cluster
After Fukushima, there has been an increase in deaths in the United States － This has been corroborated by findings of deaths, particularly of children younger than 1 year in British Columbia
U.S.Nuclear Authorities publicly stated that only a tiny amount of radionuclides from Fukushima fell on North America. If that’s true, it’s possible that considerable levels of internal exposure occurred.
Research institutes in Vilnius, Lithuania and Spitsbergen (Norway) reported that radionuclides such as cesium from Fukushima have been found.
A simulation (conducted by a French government institution Atmospheric Chemistry and Physics) indicates the plume reached South East Asia, Philippines, and Indochina.

The Cyprus Institute's simulation suggested the same.
It is difficult to prove the effect of radiation exposure on health problems, but data showed increases in the numbers of sudden deaths and cancers after the Chernobyl accident.
If indeed the number of health problems rose in North America, the same may happen in other areas in the whole North hemisphere. In Japan it is getting harder to receive appropriate medical support. There are countries without adequate medial system in South East Asia. This is a source of concern.
