Topoff 4 – US To Test Response To Large Scale Dirty Bomb Attack; I posted a story on this yesterday but I liked the addition NTARC made to this story with a “Dirty Bomb Fact Sheet”

(NTARC) The United States will test this month its preparedness for a large scale terrorist attack with a dirty bomb.

“TOPOFF 4″ (Top Official 4), as the exercise is called, will be held between October 15-20.

The test will be a massive simulated attack and involve setting off fake “dirty bombs” combined with conventional explosives and radioactive material in three locations: Oregon in the northwest, Arizona in the southwest and the US Pacific island territory of Guam.

“For TOPOFF 4, approximately 15,000 federal, state, territorial and local officials will participate in a robust, full-scale response to a multi-faceted terrorist threat,” Schrader told the committee in a statement obtained by AFP.

It will “accurately simulate a truly national response to these major terrorist incidents” by emergency response teams, medical units, police forces and top government officials who will have to make difficult decisions to save lives.

The latest such exercise, “TOPOFF3,” was held in April 2005 and involved simultaneous terrorist attacks in Connecticut and New Jersey.

Congress is already raising questions

Because of recent new stories, people have expressed concern about the possibility of a terrorist attack involving radioactive materials, possibly through the use of a “dirty bomb,” and the harmful effects of radiation from such an event. The National Terror Alert Response Center has prepared a fact sheet to help you understand what a dirty bomb is and how it may affect you in an actual terrorist strike.

Dirty Bomb Fact sheet

Because of recent terrorist events, people have expressed concern about the possibility of a terrorist attack involving radioactive materials, possibly through the use of a “dirty bomb,” and the harmful effects of radiation from such an event. This fact sheet was prepared to help people understand what a dirty bomb is and how it may affect their health.

What is a Dirty Bomb

A dirty bomb, or radiological dispersion device, is a bomb that combines conventional explosives, such as dynamite, with radioactive materials inthe form of powder or pellets. The idea behind a dirty bomb is to blast radioactive material into the area around the explosion. This could possibly cause buildings and people to be exposed to radioactive material. The main purpose of a dirty bomb is to frighten people and make buildings or land unusable for a long period of time.

Dirty bomb versus atomic bombs in Hiroshima and Nagasaki

The atomic explosions that occurred in Hiroshima and Nagasaki were conventional nuclear weapons involving a fission reaction. A dirty bomb is designed to spread radioactive material and contaminate a small area. It does not include the fission products necessary to create a large blast like those seen in Hiroshima and Nagasaki.

How much expertise does it take to make a dirty bomb?

Not much more than it takes to make a conventional bomb. No special assembly is required; the regular explosive would simply disperse the radioactive material packed into the bomb. The hard part is acquiring the radioactive material, not building the bomb. The Washington Post reported in March 2002 that the Bush administration’s consensus view was that Osama bin Laden’s al Qaeda terrorist network probably had such often-stolen radioactive contaminants as strontium 90 and cesium 137, which could be used to make a dirty bomb. In January 2003, British officials found documents in the Afghan city of Herat that led them to conclude that al Qaeda had successfully built a small dirty bomb. In late December 2003, homeland security officials worried that al Qaeda would detonate a dirty bomb during New Year’s Eve celebrations or college football bowl games, according to The Washington Post. The Department of Energy sent scores of undercover nuclear scientists with radiation detection equipment to key locations in five major U.S. cities, the Post reported. The relative ease of constructing such weapons makes them a particularly worrisome threat, counterterrorism experts say. Even so, expertise matters. Not all dirty bombs are equally dangerous: the cruder the weapon, the less damage caused. We don’t know if terrorists could handle and detonate high-grade radioactive material without fatally injuring themselves first.

Is a dirty bomb a nuclear weapon?

No. Nuclear weapons involve a complex nuclear-fission reaction and are thousands of times more devastating.

Is a dirty bomb a weapon of mass destruction?

Yes, but more because of its capacity to cause terror and disruption than its ability to inflict heavy casualties, experts say. Depending on the sophistication of the bomb, wind conditions, and the speed with which the area of the attack was evacuated, the number of deaths and injuries from a dirty bomb explosion might not be substantially greater than from a conventional bomb explosion. But panic over radioactivity and evacuation measures could snarl a city. Moreover, the area struck would be off-limits for at least several months—possibly years—during cleanup efforts, which could paralyze a local economy and reinforce public fears about being near a radioactive area.

Sources of the radioactive material in Dirty Bombs

There has been a lot of speculation about where terrorists could get radioactive material to place in a dirty bomb. The most harmful radioactive materials are found in nuclear power plants and nuclear weapons sites. However, increased security at these facilities makes obtaining materials from them more difficult. Because of the dangerous and difficult aspects of obtaining high-level radioactive materials from a nuclear facility, there is a greater chance that the radioactive materials used in a dirty bomb would come from low-level radioactive sources. Low-level radioactive sources are found in hospitals, on construction sites, and at food irradiation plants. The sources in these areas are used to diagnose and treat illnesses, sterilize equipment, inspect welding seams, and irradiate food to kill harmful microbes.

Dangers of a dirty bomb

If low-level radioactive sources were to be used, the primary danger from a dirty bomb would be the blast itself. Gauging how much radiation might be present is difficult when the source of the radiation is unknown. However, at the levels created by most probable sources, not enough radiation would be present in a dirty bomb to cause severe illness from exposure to radiation.

Past use of dirty bombs

According to a United Nations report, Iraq tested a dirty bomb device in 1987 but found that the radiation levels were too low to cause significant damage. Thus, Iraq abandoned any further use of the device.

What people should do following the explosion of a dirty bomb

* Radiation cannot be seen, smelled, felt, or tasted by humans. Therefore, if people are present at the scene of an explosion from a suspected dirty bomb, they will not know whether radioactive materials were involved at the time of the explosion. If people are not too severely injured by the initial blast,they should: * Leave the immediate area on foot. Do not panic. Do not take public or private transportation such as buses, subways, or cars because if radioactive materials were involved, they may contaminate cars or the public transportation system. * Go inside the nearest building. Staying inside will reduce people’s exposure to any radioactive material from a dirty bomb that may be on dust at the scene. * Remove their clothes as soon as possible, place them in a plastic bag, and seal it. Removing clothing will remove most of the contamination caused by external exposure to radioactive materials. Saving the contaminated clothing would allow testing for exposure without invasive sampling. * Take a shower or wash themselves as best they can. Washing will reduce the amount of radioactive contamination on the body and will effectively reduce total exposure. * Be on the lookout for information. Once emergency personnel can assess the scene and the damage, they will be able to tell people whether radiation was involved. * Even if people do not know whether radioactive materials were present, following these simple steps can help reduce their injury from other chemicals that might have been present in the blast.

Taking potassium iodide (KI)

Potassium iodide, also called KI, only protects a person’s thyroid gland from exposure to radioactive iodine. KI will not protect a person from other radioactive materials or protect other parts of the body from exposure to radiation. It must be taken prior to exposure (for example, if people hear that a radioactive cloud is coming their way) or immediately after exposure to be effective. Since there is no way to know at the time of an incident whether radioactive iodine was used in the explosive device, taking KI would probably not be beneficial.Also, KI can be dangerous to some people. Taking KI is not recommended unless there is a risk of exposure to radioactive iodine.

If radioactive materials were involved

Keep televisions or radios tuned to local news networks. If a radioactive material was released, people will be told where to report for radiation monitoring and blood tests to determine whether they were exposed to the radiation as well as what steps to take to protect their health.

Risk of cancer from a dirty bomb

Some cancers can be caused by exposure to radiation. Being at the site where a dirty bomb exploded does not guarantee that people were exposed to the radioactive material. Until doctors are able to check people’s skin with sensitive radiation detection devices, it will not be clear whether they were exposed. Just because people are near a radioactive source for a short time or get a small amount of radioactive material on them does not mean that they will get cancer. Doctors will be able to assess risks after the exposure level has been determined.

  1. Overall,a good article. However, just a correction regarding the comment about low-level radioactive isotopic sources being acquired from food irradiation plants (or medical sterilization plants for that matter-same system). I would not classify the Colbalt-60 sources used in these facilities as “low-level.” It would be very difficult to harvest sources from the storage pool (sources when not in use are stored under water in a pool, which provides the shielding and cooling). Anyone attempting to steal these sources would be exposed to a very large radiation dose. Also, without the proper storage/transportation containers and tools the time factor comes into play. This is not a simple quick ‘snatch and run’ scenario. Also, some food irradiation and medical sterilization facilities use machine generated sources – linear accelerators.

  2. Im no professional on this particular source of radiation. I have to agree based on what you have said that it would be no simple snatch and run scenario. The reasearch that I have done on terrorism funding, Suspected terrorism compounds all over the U.S. 32 to my knowledge. The money these people come up with is unreal. Aerial photos of certain spots that appear to be man made ponds, compared to Aerial photos of the same area one to two years later, the ponds are gone. Your comment has raised suspicion in my mind as to exactly what these seemingly harmless ponds could be used for. Is it possible for any of these types of plants to be grown in a pond?

  4. Sorry that you feal we havn’t given you guys enough credit for stories I obtain from your site. Please remember just because we sometimes have some of the same stories dosn’t mean I obtained mine from your site, maybe the same source. I would also like to point out, that stories you guys have obviously worked very hard on I put at the end of the Heading “By the N.T.A.R.C”, so nobody confuses who the credit should go to. I focus everyday on gathering as many terrorism related stories as possible, esspecially the ones not in the Main stream media. I feal we share the same goals, “to alert as many Americans as possible about the threats we as Americans are up against” hopefully we can convince people to take these threats seriously, as they should be. Not only will I add a link to any story I obtain from your site, I will also add you to my blogroll although I thought I already had done so. (sorry)

    God Bless and Take Care
