If the U.S. does drop a strong “bunker buster” bomb on a suspected underground nuclear weapons web site in Iran, consultants in radiation hazards say there may be little danger of widespread contamination.
ANDREW LIMBONG, HOST:
As we heard earlier in this system, at present, B-2s left Whiteman Air Drive Base in Missouri. The stealth B-2 is the one airplane able to carrying the bunker-buster bombs that would attain Iran’s most well-protected nuclear facility. That’s, if the U.S. joins in Israel’s strikes in opposition to Iran, which President Trump says he’s contemplating. In the meantime, the pinnacle of the Worldwide Atomic Power Company issued a stark warning this week in regards to the hazard of assaults on nuclear websites.

RAFAEL MARIANO GROSSI: Nuclear installations are coming beneath hearth, and nuclear security is being compromised.
LIMBONG: Nuclear security is being compromised. So what’s the danger to nuclear security in a struggle zone? Becoming a member of us to debate that is NPR science correspondent Geoff Brumfiel. Hey, Geoff.
GEOFF BRUMFIEL, BYLINE: Hello there.
LIMBONG: All proper, so to begin with, a whole lot of the information this week has been centered on one among Iran’s principal nuclear websites known as Fordo. It is situated inside a mountain, and the considering is that the one solution to strike it could be with a U.S. bunker-buster bomb. However what would occur if America dropped such a bomb on Fordo?
BRUMFIEL: Properly, it isn’t clear what would occur, to be trustworthy with you. It could in all probability take a number of bombs to get by means of the mountain. And if they may, there could be a breach, however it could not set off a nuclear explosion. Now, it’s true Iran shops extremely enriched uranium in Fordo, however it’s saved as a gasoline. That implies that there is no method for it to attain that runaway nuclear chain response.
LIMBONG: However let’s assume that the bunker buster acquired by means of, after which the, you recognize, gasoline canisters have been ruptured. What would the dangers there be?
BRUMFIEL: Yeah, there could be some dangers. My colleague Nell Greenfieldboyce spoke to Emily Caffrey, a radiation well being physicist on the College of Alabama at Birmingham. Here is what she stated.
EMILY CAFFREY: The very first thing I like to inform folks about uranium is that it’s extra chemically poisonous than it’s radiologically poisonous.
BRUMFIEL: And that she means is that uranium is radioactive – that is true – however initially, it is a heavy metallic, and meaning it could actually make you actually sick should you ingest it. Now, the opposite factor to know is that uranium gasoline is admittedly heavy, so even when one among these canisters will get ruptured, it in all probability will not go very far.
CAFFREY: How far would the gasoline journey? The possible reply might be not off the location boundary as a result of it is – once more, it is a large, heavy gasoline molecule.
BRUMFIEL: So for folks dwelling close by or, you recognize, even a number of tens of miles away, like in Tehran, there’s little or no danger in any respect. And actually, the U.N. watchdog did say it thought gasoline leaked from one other web site known as Natanz after an Israeli bombing, however there is no indication but of leaks exterior that web site.
LIMBONG: OK, so that you’re saying that, you recognize, this feels like an area disaster – proper? – and perhaps staff must put on gasoline masks and hazmat fits. However the head of the Worldwide Atomic Power Company has nonetheless been sounding this warning very loudly all week. Are there different considerations?
BRUMFIEL: Yeah, there are, and that is as a result of there are different nuclear amenities in Iran that carry different dangers. So Iran has two working reactors, a industrial energy plant at Bushehr and a analysis reactor in Tehran. Now, these reactors comprise numerous radioactivity, and if both have been struck, it might unfold a whole lot of nuclear contamination over a a lot wider space. So that will be one thing extra akin to Fukushima or Chernobyl. Now, up to now, Israel would not even seem to have tried to strike these websites, however there are dangers there.
LIMBONG: All proper. Talking of Israel, we have been speaking in regards to the risks inside Iran, however are there locations to fret about within Israel?
BRUMFIEL: Yeah, Israel has a nuclear reactor in a spot known as Dimona. That reactor is a part of its nuclear weapons program, and it is conceivable Iran might attempt to strike that reactor in retaliation for strikes at its nuclear websites. And once more, if that have been to occur, it might spark a serious nuclear disaster. And, you recognize, I believe for this reason the U.N. watchdog is so nervous. We have already got reactors beneath hearth in Ukraine, and now there’s this new battle the place there’s a whole lot of nuclear amenities which can be in danger in a struggle zone.
LIMBONG: NPR’s Geoff Brumfiel. Thanks a lot, Geoff.
BRUMFIEL: Thanks.
