What would happen if a nuclear bomb hit Washington D.C.?

Daily Mail – March 17, 2012

The terrifying report that predicts damage a terror attack would wreak on the nation’s capital

It is perhaps unsurprising that a nuclear bomb set off in the nation’s capital would cause devastating and widespread damage.

Yet the simple conclusion did not put the government off, and they commissioned a report to assess the impact of a potential terror attack on Washington, D.C.

The results are far from comforting: the half-mile radius around the bomb would have a low chance of survival and most buildings – including that of the federal government – would be destroyed

The study simulated a nuclear strike on 16th and K streets, which is the heart of the city and just a couple of blocks from the White House.

Buildings including the White House, the Capitol, Treasury Department, Old Executive Office Building and many along the National Mall would be instantly destroyed

The next half mile would suffer extensive damage, fires and serious injuries, and those within three miles could suffer minor injuries and slight damage to their homes.

But it was the fallout which the National Capital Region: Key Response Planning Factors for the Aftermath of Nuclear Terrorism study – held last year – suggested could be the most fearful aspect.

It suggests that unlike bombs detonated in the Cold War, which were designed to decimate entire cities, the smaller bomb would leave survivors – and asks, what would they have to deal with?

The study, which was reported on Gizmodo, points out that radioactive fallout would vary depending on the time of year.

In April, Washington’s Bethesda area would suffer the brunt of the dust, while throughout the rest of the year, the city’s poorer regions and Northern Virginia would be exposed.

Within 10 to 20 miles of the explosion, radioactive exposure would cause nausea and vomiting within hours, and death without medical treatment.

But for those near enough to the blast, experiencing more than 800R of radiation, not seeking shelter immediately would cause deaths with or without medical treatment, the study found.

People would not be able to evacuate this area as fallout would arrive within just 10 minutes.

And for those not in this zone, many could die from the effects years later, as the fallout spreads across the country.

The report worryingly concludes: ‘The magnitude of a terrorist attack involving [such an attack] will overwhelm all response resources.’

It merely offers suggestions on how to survive, such as: ‘The best initial action immediately following a nuclear explosion is to take shelter in the nearest and most protective building or structure and listen for instructions from authorities.’

‘After an unexplained dazzling flash of light, do not approach windows, and stay behind cover for at least a minute to prevent injuries from flying and falling debris, such as broken glass.’

It adds: ‘People should expect to remain sheltered for at least 12 to 24 hours.

‘During that time, the intensity of fallout radiation will decrease greatly, allowing for less hazardous egress from dangerous fallout areas.’

The study also shows diagrams of houses and suggests which type of home is best designed to protect you from radiactive poisoning.

The worst areas are outside home and the tops of apartment blocks, it explains. Buildings without basements offer ‘slight’ protection and those with basements are ‘adequate’. Best of all are properties with shelters.
