How Radiation from Fukushima is now in the USA In a compelling YouTube presentation by Arnie Gundersen from Fairwinds, the complex aftermath of the Fukushima disaster is dissected, focusing specifically on the explosion at Unit 3. This presentation raises significant concerns about the implications of radioactive materials released during the incident and their potential impact on locations as far away as the United States.

Key Takeaways from the Presentation​

1. Explosion Dynamics: Gundersen delves into the nature of the explosion at Unit 3, explaining the difference between "detonation" and "deflagration." A detonation, which occurs when a shock wave travels faster than the speed of sound, is distinctly more destructive than a deflagration, where the shock wave moves at slower speeds. The explosion at Unit 3 was characterized as a detonation, indicating its significant magnitude compared to the explosion at Unit 1.
2. Evidence of Contamination: Notably, Gundersen highlights alarming evidence of radioactive materials, such as uranium and plutonium, being found in locations far from the plant, including Hawaii and even the East Coast of the United States. This spread suggests that fine particles of these elements were aerosolized during the explosion and carried by winds across large distances.
3. Unresolved Questions: The presentation raises critical questions about what exactly caused the types of explosions observed at Fukushima. Gundersen posits that while a hydrogen-oxygen reaction may have initiated the explosion, it is likely that a more intense nuclear reaction contributed to the catastrophic outcome at Unit 3.
4. Need for Post-Investigation: There is an ongoing debate about the nature of the chemical reactions within the fuel pools, which ultimately led to the large-scale explosion. Gundersen notes that there are methods to analyze the isotopes from the smoke to determine the specifics of the reactions that took place.
