New Data Supports Previous Fairewinds Analysis, as Contamination Spreads in Japan and Worldwide

Newly released neutron data from three University of California San Diego scientists confirms Fairewinds' April analysis that the nuclear core at Fukushima Daiichi turned on and off after TEPCO claimed its reactors had been shutdown. This periodic nuclear chain reaction (inadvertent criticality) continued to contaminate the surrounding environment and upper atmosphere with large doses of radioactivity.

In a second area of concern, Fairewinds disagrees the NRC's latest report claiming that all Fukushima spent fuel pools had no problems following the earthquake. In a new revelation, the NRC claims that the plutonium found more than 1 mile offsite actually came from inside the nuclear reactors. If such a statement were true, it indicates that the nuclear power plant containments failed and were breached with debris landing far from the power plants themselves. Such a failure of the containment system certainly necessitates a complete review of all US reactor containment design and industry assurances that containments will hold in radioactivity in the event of a nuclear accident. The evidence Fairewinds reviewed to date continues to support its April analysis that the detonation in the Unit 3 Spent Fuel pool was the cause of plutonium found off site.

Third, the burning of radioactive materials (building materials, trees, lawn grass, rice straw) by the Japanese government will cause radioactive Cesium to spread even further into areas within Japan that have been previously clean, and across the Pacific Ocean to North America.

And finally, the Japanese government has yet to grasp the severity of the contamination within Japan, and therefore has not developed a coherent plan mitigate the accident and remediate the environment. Without a cohesive plan to deal with this ongoing problem of large scale radioactive contamination, the radioactivity will continue to spread throughout Japan and around the globe further exacerbating the problem and raising costs astronomically.

Total radiation dose from natural and artificial sources is 0.8 to 3 mSv (milliSieversts) per year depending on local radiation levels (pre Fukushima values). 

All military tables for radiation related danger are for external exposure, not for inhaled or ingested radioactive sources. 

List of radiation dose and related danger:

10 µRems 0.1 µSv - Background radiation

100 µRems  1 µSv - Low level radiation
1 mRems   10 µSv - Daily human limit RATE

10 mRems 100 µSv - Do not stay here

100 mRems 1 mSv  - Substantial exposure
1 Rem        10 mSv  - CDV-715 lowest scale
10 Rems 100 mSv  - Extreme danger 

100 Rems  1 Sv   - 50% chance of death
500 Rems  5 Sv   - CDV-715 highest scale
