Taking to the air on hunt for dirty bomb threats

By Dugald McConnell and Brian Todd

Residents of Washington may be surprised by a helicopter flying low overhead this week, endlessly prowling the city to map its radiation signature.

The helicopter is crisscrossing the city, like a lawn mower covering a lawn, flying as low as just 150 feet off the ground. CNN spotted it northwest of downtown on Monday, flying low over the buildings, back and forth, east to west.

The purpose: to produce a baseline scan of the natural radiological readings in the capital. Once the map is done, any new anomalies - or suspicious radioactive activity - could be more easily detected.

If authorities ever need to find stolen radioactive material in the capital or a dirty bomb, they would want to be able to separate out any new spikes in the radioactivity readings.

"If sometime in the future you have a reason to be looking for something radiological, it's very necessary to have the original background so you don't chase a high-radiation area that's part of the background," said Joseph Krol of the National Nuclear Safety Administration, which is conducting the work.

"If there was some type of threat," he said, "we would do the aerial survey first." Then, officers with sensors would go on foot to the location where an anomaly was found. A team could be deployed anywhere in the country within two hours, he said.

"The way we operate," he said, "we assume every time we get a call, that this is the big one."

The scan of the District of Columbia will cover 70 square miles and take about two weeks to complete. But if authorities were urgently trying to find nuclear material, Krol said, "we would hope that scanning the entire city would not be necessary. You always have other indicators, like intelligence, that narrows down the search area."

A dirty bomb - a bomb with no atomic explosion, but spewing enough radioactive material to require evacuations and quarantines - is a method of attack that terrorists would be highly interested in, according to Randy Larsen with the Institute for Homeland Security.

"The good news is, it wouldn't kill a lot of people," he said. "But if you did it here in downtown Washington D.C., or Wall Street in New York City, and the people can't go back in that area for a long time, that's a pretty significant event."

But could a hidden dirty bomb be detected from a helicopter?

"Absolutely," said Larsen, but only after a detailed scan has been done. "This would tend to make something stick out like a sore thumb. Without it, it would be looking for a needle in a haystack."

Two pilots, a scientist, a technician and equipment for detecting gamma radiation are aboard the flights.

Everyday radiation can come from several common urban sources, including industrial sites, construction sites, hospitals that use radiological materials, and even the stone used in buildings and monuments.

The agency has already scanned the capital once before, as well as New York, Baltimore, and San Francisco.

Larsen said the New York scan turned up unexpected sources of radiation - industrial accidents that were never been reported. "They were surprised how many hot spots they found," he said.

The helicopter in Washington is making an exception for the National Zoo, giving it a wider berth to avoid scaring the animals. But Krol said the public should not be worried about the survey's potential impact on people.

"These scanners are passive," he said. "All they're doing is measuring the emanations coming from the ground."

She will have to visit cities both large and small, taking care to speak only to real Americans, dispensing her sage advice and folksy, homespun common sense solutions. We can be a great nation again but we must all follow the "Palin Path".

If a citizen, who sees murders, robberies, rapes etc being committed every day, expresses a wish to own a firearm for protection, they are labeled "Paranoid gun nuts" by the Liberal establishment. But the Government, spending Millions of dollars on Zombie Apocalypse or dirty bomb scenarios, is considered protecting people?

    We have a do nothing congress whos more concerned with enriching their own wealth at our expense, and telling us what kind of light bulbs we should have in our home. The real terrorists are in washington, and in the banks that control it.

    Like the copter that was sent up over DC looking for intelligent life, this radiation sniffing copter won't find anything.

      It's not supposed to find anything – it's creating a baseline map so that any anomalies found in future will be evident and can be investigated.

    A radiation signature is the BS that comes out of people's mouths, right? Won't they need more than one helicopter to map DC?

    How come only one helicopter is assigned to this project? Doesn't sound like much of a serious effort.

      Well it's not an urgent effort, and using one set of detection devices is preferred because it simplifies the calibration. If you use multiple devices, they have to be calibrated against one another to produce meaningful results.

    So, they are producing a base line map. What if they find a hot spot? Hmmmm.... I bet they would find some real interesting things if they flew over Nevada.

      What a lame cover story – after they got caught by CNN – to say they are doing a baseline mapping. I wonder what really instigated this survey. It certainly wasn't proactive. Also, what about all of this malarkey about there being radiation detectors at all of the ports, bridges, etc.? I thought they were supposed to be effective in alerting to any radioactive material being moved around.

      I bet Washington lost something and that was their cover story.

      Also, now terrorists know where to plant or build a bomb... The zoo.

        Sure, if an explanation sounds logical but too simple, it clearly is a cover for yet another complicated and diabolical government scheme which requires the silence and cooperation of about 100,000 people who are usually too stupid to do their regular jobs correctly and who communicate poorly between departments. It's kinda like saying the staff at the DMV is plotting the covert takeover of Iran.

    One way a dirty bomb could still be planted and not be detected would be for it to be planted where some known natural radiation source had been removed. With the right amount of shielding, it would more or less replace the known source with another one and it would look enough like the original item it would not be easily detected.

      Like "Everyday radiation can come from several common urban sources, including industrial sites, construction sites, hospitals that use radiological materials, and even the stone used in buildings and monuments."

    Ok, we know where the dirty bomb will be planted, at the zoo. Clever way to cut down on the work required after a threat. lol.

    Seriously, they probably should repeat the scan at intervals because things can change over time as new buildings are built, messes cleaned up, new radiation treatment machines installed, etc.

        They do, though. From potassium-40, just like most living or formerly living things. I used to measure radiation for a living, have seen the potassium-40 gamma ray many times, and had myself scanned every year as most radiation workers are. Saw it in that measurement, too. An elephant would emit quite a lot of radiation, being so big.

    I'm surprised these were not done decades ago. All of our major cities and ports should already have these maps. Does anyone in Homeland Security have experience in the Boy Scouts – "Be Prepared"???? This does not involve exotic new technology.

    And publicly stating that you are excluding the National Zoo (put up sign saying store dirty bomb here!) It would not take that long to survey the zoo and I've certainly seen helicopters overfly it.

      They wont overfly in helicopters but they can map just as well from a vehicle or person walking through the zoo – a much lower profile approach.

        Not so much, the buildings get in the way of the gamma rays. You can't see behind them very well that way because building facade materials are fairly good gamma ray shielding. Looking down through roofing material and into backyards and so forth from above gives a much more complete picture.

      Just because the zoo isn't being scanned by the helicopter doesn't mean it isn't being scanned. If the equipment is small enough to fit in a helicopter, I'm sure it can be carted through the zoo.
