Japan Radioactivity Spreading to West Coast of US

Click For Summary

Discussion Overview

The discussion revolves around the potential spread of radioactivity from Japan to the West Coast of the United States following nuclear reactor meltdowns. Participants explore the implications of such events, the mechanisms of radioactivity dispersal, and public reactions to perceived risks.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation

Main Points Raised

  • Some participants express skepticism about the likelihood of significant radioactivity reaching the West Coast, citing historical precedents such as the atomic bombings in 1945.
  • One participant suggests that any radioactivity released would be diluted significantly during transit, posing almost no health hazard upon arrival.
  • Another participant references a live geiger counter in Tokyo showing normal background radiation levels, arguing that California is not in danger from the situation.
  • There are mentions of public panic, with some participants mocking the rush to purchase iodine pills as indicative of uninformed decision-making regarding nuclear policy.
  • A participant notes that the nuclear engineering community at Berkeley is actively monitoring air and rainwater for traces of fission products, indicating ongoing scientific investigation into the matter.

Areas of Agreement / Disagreement

Participants generally disagree on the level of risk posed by potential radioactivity reaching the West Coast, with some asserting it is negligible while others express concern over public perception and policy implications. The discussion remains unresolved regarding the actual risk assessment.

Contextual Notes

Participants reference different scenarios of nuclear incidents, highlighting the complexities in comparing a nuclear blast to a reactor meltdown. There are also varying interpretations of the data from monitoring stations, which may influence risk perceptions.

There is a lot of speculation about this. Is that really possible?

It is being proposed that after meltdown and release the nuclear material will enter the Jet Stream and be in west Coast US in a few days.

Personally I find it hard to swallow. I mean we exploded two nuclear devices over Japan in 1945 and did not experience widespread nuclear contamination in the US.. A core meltdown devastates the soil, water and local air.. for at least a few hundred miles, but by the time anything enters the Jet Stream, etc.. how powerful could it be?

I realize these are different scenarios, a nuclear blast and a core meltdown in a nuclear reactor.. (with the Atomic explosion MUCH MORE SEVERE).

So, is there any scenario whereby even if four core meltdowns occur and their radioactivity gets released, that the West Coast of US needs to worry.

Am I missing something here?

Thanks a lot

The amount released from the damaged reactors would be diluted so much on its way here that it should pose almost no health hazard. I laughed when I saw on the news that Iodine pills were selling out all along the west coast here in the US. (Of course I could be wrong, but then I'm glad i live in Louisiana instead of California.)

I read that too while I was eating, had to spit out my water laughing. Unfortunately, it's people like that that will be deciding public policy about reactors going forward...

Yep. Nothing better than uninformed decision makers eh? Oh wait...
 
To put this in perspective - there is an online live geiger counter in Tokyo. Tokyo is south of the plant a ways and it is reading normal background levels of radiation still.

California is in *no* danger from this. I can't imagine what the Surgeon General is thinking.

KEK (in Tsukuba, outside Tokyo) is currently detecting atmospheric 131I at 2.7×10-7 Bq/cm3.

That's absolutely tiny... I doubt it will be detectable at all on the other side of the pacific. There's absolutely no way in hell it's harmful.

It may be detectable. The nuclear engineering community at Berkeley are currently running air and rainwater samples as we speak, looking for traces of those fission products.
