More advice on best actions to survive a nearby nuclear blast

Posted by in categories: existential risks, military, nuclear weapons

Carnegie Mellon researchers Keith Florig and Baruch Fischhoff offer simple, practical advice: on whether it is worth citizens’ time to stock supplies needed for a home shelter, how urgently should one seek shelter following a nearby nuclear detonation, and how long should survivors remain in a shelter after the radioactive dust settles.


“A number of emergency-management organizations recommend that people stock their homes with a couple dozen categories of emergency supplies,” said Florig of Carnegie Mellon’s engineering and public policy department. “We calculated that it would cost about $240 per year for a typical family to maintain such a stock, including the value of storage space and the time needed to tend to it.”

Their research also suggests that many families who could afford to follow the stocking guidelines might think twice about whether the investment was really worth it, given the low probability that stocked supplies would actually be used in a nuclear emergency.

They advocate simple rules for minimizing risk based on how far people are from the blast. If you are within several miles of the blast, there will be no time to flee and you will have only minutes to seek shelter. If you are 10 miles [downwind] from the blast, you will have 15 to 60 minutes to find shelter, but not enough time to reliably flee the area before the fallout arrives,” said Florig.

Nuclear Terrorism Blast Maps

That’s what the radius of destruction would look like if a 10 kT nuke were detonated on top of my house! Put in your own zip code, and see how bad it would be for you.

I found this page by following a link from NTI, the global security organization founded by Ted Turner. Warren Buffet is another billionaire who supports NTI and encourages his shareholders to read books and watch films about the threat of nuclear terrorism.

U.S. Envisions A New Generation Of Nuclear Weapons

Posted by in category: nuclear weapons

Science Daily — Almost 62 years after detonation of the first atomic
bombs, the United States is considering controversial proposals to
produce a new generation of nuclear weapons and revamp its nuclear
weapons complex, according to an article scheduled for the March 19
issue of Chemical & Engineering News (C&EN), ACS’ weekly newsmagazine.

In the article, C&EN senior editor Jeff Johnson points out that the
proposals come at a time of growing fears about potential new nuclear
powers, such as North Korea and Iran, and potential diversion of
nuclear weapons into the hands of terrorists. The U.S. Department of
Energy’s National Nuclear Security Administration (NNSA), which
oversees design, production and maintenance of nuclear weapons,
developed the proposals.

One part of the plan, for instance, calls for production of the
“renewable, replacement warhead (RRW),” a new nuclear weapon that NNSA
says will be easier and environmentally cleaner to manufacture and
more difficult for potential terrorists to disassemble or detonate.

Reducing nuclear bomb casualties

Posted by in categories: defense, existential risks, nuclear weapons

Some information on how to reduce nuclear bomb casualties

If you are downwind of the blast, look at tree tops to see direction of wind and then flee perpendicular to the wind. Because the plumes are significantly longer than they are wide, moving as little as one to five miles perpendicular to the plume can mean the difference between life and death. People in areas upwind of the detonation site, on the other hand, are safest staying where they are.

Today’s hospital burn units provide exemplary but time consuming care to burn victims, who typically arrive sporadically and in small numbers. A nuclear attack would bring a sudden surge of patients, but the medical system could dramatically minimize fatalities by training staff and equipping non-medical people to treat second-degree burn victims in much larger numbers. The focus must be on cleaning the wounds to avoid fatal infections, administering painkillers and then moving on to the next patient. And all of this must occur in the field, since thousands of victims would not make it to a hospital.

Nuclear terrorism risk seen growing

Posted by in categories: existential risks, nuclear weapons

Two new reports on global security conclude with a growing risk for nuclear terrorism Reuters report today.

The EastWest Institute and Chatham House, the two think-tanks behind the reports, cite that more states are pursuing their own nuclear ambitions and that the materials and engineering effort for a bomb “have all become commodities, more or less available to those determined enough to acquire them”.

The vulnerability of nuclear power plants are mentioned. This is highly relevant considering all the new power plants under planning or construction. Read about the planned terrorist attack on a nuclear power plant in Australia, “Australia nuclear plant plot trial opens in Paris”, Reuters.

But most suprisingly:

Enriched Uranium Sale in Georgia Disrupted

North Korea is helping Iran to prepare an underground nuclear test similar to the one Pyongyang carried out last year.

Under the terms of a new understanding between the two countries, the North Koreans have agreed to share all the data and information they received from their successful test last October with Tehran’s nuclear scientists.

Iranian official: If threatened, we will use nuclear weapons

Posted by in categories: geopolitics, nuclear weapons

From Ynet News:

Iran’s chief nuclear envoy Ali Larijani said on Friday that Iran is committed to the peaceful use of nuclear technology but warned the situation could change if his country is threatened.” We oppose obtaining nuclear weapons and we will peacefully use nuclear technology under the framework of the Nonproliferation Treaty, but if we are threatened, the situation may change,” He told a news conference after two days of talks in Beijing. Iran’s nuclear chief said his country has produced and stored 250 tons of the gas used as the feedstock for uranium enrichment, state-run television reported Friday.Vice President Gholamreza Aghazadeh, who is also the head of the Atomic Energy Organization of Iran, said Iran has kept the uranium hexaflouride gas, or UF-6, in underground tunnels at a nuclear facility in Isfahan to protect it from any possible attack.“Today, we have produced more than 250 tons of UF-6. Should you visit Isfahan, you will see we have constructed tunnels that are almost unique in the world,” State-run television quoted Aghazadeh as saying.
