Electromagnetic Pulse: An Avoidable Disaster

By Paul M. Weyrich

Although the risk of your house catching fire and burning to the ground is remote, are you willing to risk not having fire insurance?

That's a question that Rep. Roscoe Bartlett (R-MD) poses, and the answer that I think you and I would give without hesitation is "no."

Our country is unprepared to deal with a nuclear explosion at a high altitude. The danger would be more than merely life or limb. A nuclear explosion over Chicago, for example, could plunge a large portion of our country into darkness, with electricity lost for days, even months, perhaps in some places years. All computerized activity in the region would cease. The culprit: High Altitude Electromagnetic Pulse.

The very day the 9/11 Commission report was issued another report, that may one day prove itself to be even more important to our security, also was released. "The Report of the Commission to Assess the Threat to the United States from Electromagnetic Pulse Attack" stated that our country has the ability to prevent the worst-case scenarios from occurring in this age of international terrorism.

When NATO started to bomb the Serbs in the spring of 1999 to stop Slobodan Milosevic's expulsion campaign against ethnic Albanians, the Russians were very unhappy about our military aggressions against one of their longtime allies. Rep. Bartlett was part of a bi-partisan delegation assembled by Rep. Curt Weldon (R-PA) to examine the situation. They conferred with some counterparts from the Russian Duma. One Duma member, Vladimir Lukin (at the time chairing the Duma's International Affairs Committee and formerly a high-level member of the Soviet national security apparatus under Gorbachev), threatened that if Russia really wanted to hurt without fear of retaliation, Russia would launch a missile against us from a submarine, explode it high over our skies and shut down our power grid and communications for six months.

Rep. Bartlett was very disturbed by what he had heard; he wanted to know if the Russians were bluffing and sought the opinions of our country's military experts. After he found that the Clinton Administration was ignoring the threat, Rep. Bartlett decided to establish the Electromagnetic Pulse (EMP) Commission. The EMP Commission was established by unanimous consent of the House and Senate.

If a nuclear blast occurred in high altitudes over our country, people would not be killed by the fallout from the blast itself. The most serious and far-reaching damage would be done by the EMP emissions. The result? According to the report, "the 'electromagnetic shock' that disrupts or damages electronics-based control systems, sensors, communication systems, protective systems, computers, and similar devices. Its damage or functional disruption occurs essentially simultaneously over a very large area." One scenario outlined by the EMP Commission predicted that a blast over Chicago, where 70% of our country's total power generation occurs, would instantly impact cities as distant as New York and Washington, D.C.

Important economic and life-sustaining sectors that stand to be severely damaged or shut down are our electronic power infrastructure, telecommunications, banking and finance, transportation, fuel/energy, food and emergency services, water supply, space systems and government operations.

An EMP attack cannot be compared to an ordinary blackout, even a very large blackout, because it will occur over a greater area, damage major electronic systems and cause recovery to be measured in months.

Here is some of the damage that stands to occur immediately after an attack unless sensible "hardening" precautions are taken to protect data and systems. They are:

Electronic records in computers, such as your savings and checking accounts, would be inaccessible.

Your telephone line, even for a cellular, would go dead.

The systems that operate petroleum refineries would be stopped, forcing energy production to halt for some time.

Transportation would be disrupted. Car and truck engines, train engines would be disabled. Traffic signals would become inoperable. Our air traffic control system would cease to exist.

Calling 911 would be a thing of the past.

The EMP Commission report warned: "Many citizens would be without power, communications and other services for days - or perhaps substantially longer - before full recovery could occur. During that interval, it will be crucial to provide a reliable channel of information to those citizens to let them know what has happened, the current situation, when help of what types for them might be available, what their governments are doing, and the host of questions which, if not answered, are certain to create more instability and suffering for the affected individuals, communities, and the Nation as a whole."

The Boy Scout motto -- "Be prepared" -- is sound advice for our nation's policymakers in this era of global terrorism. They cannot afford to ignore this report or its warnings or other warnings that biological and chemical warfare agents, cyber attacks and surface-burst nuclear weaponry are other significant threats. Those types of attacks would be the more deadly when combined with an EMP attack.

There are steps we can take to increase our ability to quickly recover from an EMP attack. For example, the Department of Homeland Security should have a list that prioritizes emergency electricity delivery to hospitals, regional food warehouses, water supply and critical communications and transportation. Preparing and protecting spare transformers could quickly repair the power grid and permit the recovery of electric power, enabling other important infrastructures to be functional. The EMP Commission made the point that we need wise and effective planning; it needs to be done now.

The Wall Street Journal did not ignore the Commission's report on the perils of an EMP attack. It published an editorial warning that China and Russia have the capability to launch an EMP strike against us. Over the next 15 years our relations with these countries are likely to be volatile and unpredictable. Russian Duma members threatened us five years ago. Chinese publications have carried articles about EMP, including threats to use EMP to neutralize our aircraft carriers if we were to war with China over Taiwan. The Commission appeared most concerned about an EMP attack from terrorists or rogue states who believe they have absolutely nothing to lose.

Wall Street is indeed concerned about this problem. The EMP Commission delivered a briefing to the Securities Industry Automation Corporation, which handles the communications networks responsible for the New York Stock Exchange. EMP Commissioner Lowell L. Wood, Jr. estimated in an Aerospace Daily & Defense Report article published earlier this fall that, all told, an EMP attack that shuts down our critical infrastructure systems could carry a $10 trillion dollar price tag.

The nine members who served on the EMP Commission have strong credentials: Commission Chairman, Dr. William R. Graham, served as Director of the White Office of Science & Technology Policy and as Science Advisor to President Ronald Reagan; General Richard L. Lawson, USAF, Ret., is a former President and CEO of the National Mining Association; Dr. Lowell L. Wood is Senior Staff Scientist at the Lawrence Livermore National Laboratory.

Rep. Bartlett brings a unique skill set: With a master's degree in physiology, he worked at the John Hopkins Applied Physics Laboratory, directing a unit in Space Life Sciences and at IBM on biomedical engineering projects. He speaks on this issue with a background in the sciences. At 78 years of age, he has the energy and drive that would shame many young people.

Bartlett is undeterred by the lack of response from the establishment news media, driven by his understanding of what may truly be at stake if our nation's policymakers and business leaders continue to ignore the EMP Commission's work. Some have called the 9/11 Commission report a look in the rear view mirror. By contrast, the EMP Commission report is a look down the road at the kind of attack that instantaneously could change our status as the world's superpower to that of a nation with an infrastructure so diminished that Third World nations might be envied.

Many important issues will be taken up by the next Congress, starting in January. This issue deserves strong consideration as does our ability to deal with other kind of attacks, such as biological warfare, that represent the deadly future of warfare and terrorism. If the worst case scenario were to occur, it also would be important that our public officials respond in a manner that seeks to preserve our liberties and heritage as much as possible.

Rep. Bartlett advises that sensible steps taken now can prepare us to deal with, even thwart, the mayhem caused by terrorists and rogue nations. I hope we have some lawmakers who share Mr. Bartlett's concern in preserving our American way of life for future generations. If we do, then I expect Congress will delve further into the work of the EMP Commission and its unsettling findings.

Paul M. Weyrich is Chairman and CEO of the Free Congress Foundation.

Do we have any more info on EMP. What it effects. Like is it only very sensitive, low wattage equipment like PC’s or things like cars and elect motors. And will it only disrupt things that are operating at the time, or can it perminitly knock out idle motors. And can it disrupt the human nervous system ? Is the "wave" short or long term and will effect battery operated lights ? Stuff like that.

Nuclear Weapon EMP Effects
 
A high-altitude nuclear detonation produces an immediate flux of gamma rays from the nuclear reactions within the device. These photons in turn produce high energy free electrons by Compton scattering at altitudes between (roughly) 20 and 40 km. These electrons are then trapped in the Earth’s magnetic field, giving rise to an oscillating electric current. This current is asymmetric in general and gives rise to a rapidly rising radiated electromagnetic field called an electromagnetic pulse (EMP). Because the electrons are trapped essentially simultaneously, a very large electromagnetic source radiates coherently.
 
The pulse can easily span continent-sized areas, and this radiation can affect systems on land, sea, and air. The first recorded EMP incident accompanied a high-altitude nuclear test over the South Pacific and resulted in power system failures as far away as Hawaii. A large device detonated at 400�?00 km over Kansas would affect all of CONUS. The signal from such an event extends to the visual horizon as seen from the burst point.
 
The EMP produced by the Compton electrons typically lasts for about 1 microsecond, and this signal is called HEMP. In addition to the prompt EMP, scattered gammas and inelastic gammas produced by weapon neutrons produce an “intermediate time�?signal from about 1 microsecond to 1 second. The energetic debris entering the ionosphere produces ionization and heating of the E-region. In turn, this causes the geomagnetic field to “heave,�?producing a “late-time�?magnetohydrodynamic (MHD) EMP generally called a heave signal.

Initially, the plasma from the weapon is slightly conducting; the geomagnetic field cannot penetrate this volume and is displaced as a result. This impulsive distortion of the geomagnetic field was observed worldwide in the case of the STARFISH test. To be sure, the size of the signal from this process is not large, but systems connected to long lines (e.g., power lines, telephone wires, and tracking wire antennas) are at risk because of the large size of the induced current. The additive effects of the MHD-EMP can cause damage to unprotected civilian and military systems that depend on or use long-line cables. Small, isolated, systems tend to be unaffected.
 
Source Region Electro-magnetic Pulse [SREMP] is produced by low-altitude nuclear bursts. An effective net vertical electron current is formed by the asymmetric deposition of electrons in the atmosphere and the ground, and the formation and decay of this current emits a pulse of electromagnetic radiation in directions perpendicular to the current. The asymmetry from a low-altitude explosion occurs because some electrons emitted downward are trapped in the upper millimeter of the Earth’s surface while others, moving upward and outward, can travel long distances in the atmosphere, producing ionization and charge separation. A weaker asymmetry can exist for higher altitude explosions due to the density gradient of the atmosphere.
 
Within the source region, peak electric fields greater than 10 5 V/m and peak magnetic fields greater than 4,000 A/m can exist. These are much larger than those from HEMP and pose a considerable threat to military or civilian systems in the affected region. The ground is also a conductor of electricity and provides a return path for electrons at the outer part of the deposition region toward the burst point. Positive ions, which travel shorter distances than electrons and at lower velocities, remain behind and recombine with the electrons returning through the ground. Thus, strong magnetic fields are produced in the region of ground zero. When the nuclear detonation occurs near to the ground, the SREMP target may not be located in the electromagnetic far field but may instead lie within the electro-magnetic induction region. In this regime the electric and magnetic fields of the radiation are no longer perpendicular to one another, and many of the analytic tools with which we understand EM coupling in the simple plane-wave case no longer apply. The radiated EM field falls off rapidly with increasing distance from the deposition region (near to the currents the EMP does not appear to come from a point source).
As a result, the region where the greatest damage can be produced is from about 3 to 8 km from ground zero. In this same region structures housing electrical equipment are also likely to be severely damaged by blast and shock. According to the third edition of The Effects of Nuclear Weapons, by S. Glasstone and P. Dolan, “the threat to electrical and electronic systems from a surface-burst EMP may extend as far as the distance at which the peak overpressure from a 1-megaton burst is 2 pounds per square inch.�?
 
"Society has entered the information age and is more dependent on electronic systems that work with components that are very susceptible to excessive electric currents and voltages." Many systems needed are controlled by a semiconductor in some way. Failure of semi-conductive chips could destroy industrial processes, railway networks, power and phone systems, and access to water supplies. Semiconductor devices fail when they encounter an EMP because of the local heating that occurs. When a semi-conductive device absorbs the EMP energy, it displaces the resulting heat that is produced relatively slowly when compared to the time scale of the EMP. Because the heat is not dissipated quickly, the semiconductor can quickly heat up to temperatures near the melting point of the material. Soon the device will short and fail. This type of failure is call thermal second-breakdown failure.
 
"The worst of the pulse lasts for only a second, but any unprotected electrical equipment - and anything connected to electrical cables, which act as giant lightning rods or antennas, will be affected by the pulse. Older, tube or valve-based equipment is much less vulnerable to EMP. "Most of the energy is distributed throughout the lower frequencies between 3 Hz and 30 kHz.
 
The Electro-Magnetic Pulse will electrify all sorts of metallic structures that are not normally electrified except by the occasional short circuit or lightening strike. This will be a lot like the whole country getting struck by lightening all at the same time.
 
As computer chips make better and better use of "real estate", using more and more delicate electronic circuits, the more tightly-packed transistors, capacitors, diodes and resistors become more and more vulnerable to the EMP which will be carried into the chips via the connecting wires. The Electro-Magnetic Pulse is one of the reasons above-ground testing was stopped.
 
EMP is unlikely to harm most people, Pacemakers, for example, may stop working because of the "hit" from the EMP. It will be quite something to see people in a thousand mile radius of the epicenter of the blast (or further) who are using pacemakers, suddenly drop dead, and all the computers permanently go down and all the lights go out, all at the same time. And commercial and private aircraft will drop out of the sky, since their sensitive electronics and fly-by-wire systems are not very well shielded from the EMP. These planes will then not be available for evacuation purposes, nor will they be available to air-drop food, water, morphine and cyanide, all of which will be in great demand throughout the area.
 
Home plumbing systems and most other plumbing systems are good examples of large metallic structures that will suddenly become electrified, destroying the motors, gauges, electronics, etc. which are attached to the plumbing systems. More and more pumping equipment is computer controlled nowadays for efficiency. Imbedded controllers are becoming prevalent but as they do, the potential damage from the Electro-Magnetic Pulse increases dramatically.
 
In plain language, it is an electromagnetic "shock wave" that is released from nuclear detonations that can seriously damage any electrical components in its path. EMP can travel either through air or through conductive pathways such as electrical or phone lines. It can affect electronic equipment regardless of whether the equipment is switched on or off.

I always wondered if we could get an effect like that from a passing metor or even a very severe "sun burst".
I know the little ones can screw up tv reception !
