What Does A Neutron Beam Look Like? Deadly Neutron Radiation Poisoning Accident Via Demon Plutonium Core Killed Scientists; How And Why Neutron Radiation Kills People At Long Distances, Geiger Counter Radiation Detectors Do Not 'See' This Type Of Radiation




The Engineers at the Nuclear Engineering Teaching Lab (NETL) at the University of Texas in Austin demonstrate a reactor pulse, which creates a neutron 'beam'. (underwater version)

The control rods are removed, and power ramps up to 680MW FOR 50 milliseconds. This reactor, a TRIGA Mark II, is only capable of 1 MW steady state over longer periods of time.

A neutron beam is the result of nuclear fission happening in an uncontrolled fashion. As the fission happens, it generates heat, 'blue light' and radiation, plus a neutron beam or as some people describe it, neutron radiation. The blue flash of light that is created as a byproduct of fission is visible both in the air, and underwater. 

If water is not filtering and absorbing the neutrons and radiation, and you were close enough to see the blue flash of light, you are more than likely also close to enough to be dead, due to the intense neutron, alpha, beta and gamma radiation that goes along with this blue flash of light.

DEMON CORE AND NEUTRON RADIATION


To illustrate how deadly dangerous a neutron beam can be, the following story is shared, thanks to Wikipedia; 

"The Demon core was a 6.2-kilogram (14 lb; 1 st), 3.5-inch-diameter (89 mm) subcritical mass of plutonium which went briefly critical in two separate accidents at the Los Alamos laboratory in 1945 and 1946. Each incident resulted in the acute radiation poisoning and subsequent death of a scientist. After these incidents the spherical plutonium pit was referred to as the "Demon Core."

The Demon Core was used in the first atomic bomb test to be conducted after World War II, five weeks after the second fatal accident. It performed normally and with the same explosive yield as the next core used in this set of two tests.

First incident



A re-creation of the 1945 incident. The sphere of plutonium is surrounded by neutron-reflecting tungsten carbide blocks.

On August 21, 1945, the plutonium core produced a burst of neutron radiation (a neutron beam) that caught Harry Daghlianin it's path. Daghlian was a physicist who made a mistake while working alone performing neutron reflection experiments on the core. 

The core was placed within a stack of neutron-reflective tungsten carbide bricks, and the addition of each brick moved the assembly closer to criticality. While attempting to stack another brick around the assembly, Daghlian accidentally dropped it onto the core and thereby caused the core to go critical, a self-sustaining chain reaction.

Despite quick action in moving the brick off the assembly, Daghlian received a fatal dose of radiation. He died 25 days later from acute radiation poisoning.[1]

Another person who was in the lab at the time of the accident—Private Robert J. Hemmerly, a Special Engineer Detachment (SED) guard—received an exposure of approximately 31 roentgens (0.31 Gy) of soft X-rays (80 kV equivalent) and less than 1 roentgen (0.01 Gy) of gamma rays. Hemmerly died in 1978 (33 years after the accident) from acute myelogenous leukemia at the age of 62.[2]

Second incident





A re-creation of the 1946 incident. The half-sphere is seen but core inside is not. Note the beryllium hemisphere held up with a screwdriver.

On May 21, 1946,[3] physicist Louis Slotin and seven other Los Alamos personnel were in a Los Alamos laboratory conducting an experiment to verify the exact point at which a subcritical mass (core) of fissile material could be made critical by the positioning of neutron reflectors. 

The test was known as "tickling the dragon's tail" for its extreme risk.[4] It required the operator to place two half-spheres of beryllium (a neutron reflector) around the core to be tested and manually lower the top reflector over the core via a thumb hole on the top. 

As the reflectors were manually moved closer and farther away from each other, scintillation counters measured the relative activity from the core. Allowing them to close completely could result in the instantaneous formation of a critical mass and a lethal power excursion. 

LETHAL NEUTRON RADIATION POISONING ACCIDENT VIA DEMON PLUTONIUM CORE

Uncontrolled neutron radiation, and gamma radiation released due to allowing a criticality in a 'demon core' for a nuclear bomb, killing several participants from neutron and gamma radiation

Under Slotin's unapproved protocol, the only thing preventing this was the blade of a standard flathead screwdriver, manipulated by the scientist's other hand. Slotin, who was given to bravado, became the local expert, performing the test almost a dozen separate times, often in his trademark bluejeans and cowboy boots, in front of a roomful of observers. Enrico Fermi reportedly told Slotin and others they would be "dead within a year" if they continued performing it.[5]

While lowering the top reflector, Slotin's screwdriver slipped outward a fraction of an inch, allowing the top reflector to fall into place around the core. Instantly there was a flash of blue light and a wave of heat across Slotin's skin; the core had become supercritical, releasing a massive burst of neutron radiation (a neutron beam). 

He quickly knocked the two halves apart, stopping the chain reaction and likely saving the lives of the other men in the laboratory, though it is now known that the heating of the core and shells stopped the criticality within milliseconds of its initiation. Slotin's body's positioning over the apparatus also shielded the others from much of the neutron radiation.

He received a lethal dose of 1000 rads neutron radiation/114 rads gamma radiation[6] in under a second and died nine days later from acute radiation poisoning. The nearest person to Slotin, Dr. Alvin C. Graves, was watching over Slotin's shoulder and was thus partially shielded by him, received a high, but non-lethal radiation dose of 34 neutron/166 gamma rads.[6]

(the difference between one man dying and the other living illustrates how despite a higher gamma radiation dose, it was the high NEUTRON radiation that killed one of them, but spared the other. This one example seems to prove the hypothesis that neutron radiation is harmful, despite some nuclear experts claiming that neutron radiation cannot harm anyone, and that it is 'neutral' somehow.)

Graves was hospitalized for several weeks with severe radiation poisoning, developed chronic neurological and vision problems as a result of the exposure, and died of a heart attack 20 years later.[7]

Besides Graves, the others in the room were Stanley Allan Kline of Chicago, IL, physicist, died in 2001; Marion Edward Cieslicki of Mt Lebanon, PA, 11 neutron/11 gamma rads,[6] physicist, died of acute myelocytic leukemia in 1967, 21 years after the accident; Dwight Smith Young of Chicago, IL, photographer, 51 neutron/11 gamma rads,[6] died of aplastic anemia and bacterial endocarditis in 1973, 27 years after the accident. 

(Nuclear researchers die due to exposure of neutron radiation as well as gamma radiation, just like normal people do. The myth that nuclear power never killed anyone is a myth and fable. These nuclear radiation victims, plus many others not mentioned, are direct evidence that neutron radiation alone can kill people. Sometimes radiation kills very quickly, and sometimes very slowly, after a lot of suffering. Anyone can die from either alpha, beta, gamma or neutron radiation.)

Dr. Raemer E. Schreiber of Lafayette, IN, physicist, received a dose of 9 neutron/3 gamma rads,[6] died at 88 in 1998, 52 years after the accident;[8] Theodore Perlman of Louisiana, engineer, 7 neutron/2 gamma rads[6]), "alive and in good health and spirits" as of 1978; Pvt. Patrick J. Cleary of New York City, security guard, 33 neutron/9 gamma rads,[6] died in Korea in 1952 during the Korean War; Paul Long, machinist, and another unidentified machinist, these latter two in another part of the building.[9][10]

After Slotin's accident, hands-on criticality experiments were stopped, and remote-control machines were designed by Dr. Schreiber, one of the survivors, to perform such experiments with all personnel at a quarter mile distance.[8]

(This story illustrates the extreme danger of neutron beams and neutron radiation, which is measured in RADS. You do not want to be within at least 1/4 mile of ANY neutron beam, as the neutron radiation goes through just about anything, along with the gamma, beta and alpha radiation, all of which disrupt cells. Neutron beams go through miles of solid rock, as the high energy research facilities have proven.)

DEMON CORE IN USE 




Crossroads Able, a 23-kiloton air-deployed nuclear weapon detonated on July 1, 1946 using the Demon Core.

The Demon core was put to use for the Able detonation test of the Crossroads series on July 1, 1946.[11] Its yield was 23 kilotons, the same as the next core used in the Crossroads pair of bomb tests."

CONCENTRATED BLASTS OF NEUTRON RADIATION SUCH AS THOSE RELEASED BY NUCLEAR REACTORS OR NUCLEAR BOMBS CHANGES NORMAL HEALTHY MINERALS IN THE BODY INTO HEAVY METAL RADIOACTIVE POISONS, VIA NEUTRON CAVALCADE


Heart of the Rose April 20, 2015 "Kelley was also exposed to a cavalcade of neutrons. Neutron bombardment is often used in physics experiments to change stable atoms into isotopes likely to decay and give off radiation. This process is called neutron activation. It doesn't just happen in a lab. It happens in a human, or anything else, exposed to a concentrated blast of neutrons. Sodium-23 in the human body, for example, becomes sodium-24, a radioactive isotope which decays inside the body."

Neutron cavalcade.

SUMMARY


A neutron beam doesn't go very far in pure water, and the radiation coming from the reactor core also gets absorbed. This is why most reactors are surrounded by water and lots of it, at all times. But the opposite is true if a neutron beam happens out in open air.

This is what a neutron 'ray' looks like, as it comes out of a broken open or blown up reactor, spent fuel pool, with a melted down set of fuel rods. With no water shielding this radiation, it can and does travel for many miles, remaining lethal even after going through solid rock and metal. 

The water around the reactor however, is subjected to neutron bombardment from the reactor core. This bombardment creates radioactive tritium in the water as a reaction. This is why nuclear plants must release this radioactive tritium into the environment either in the form of gas or in the form of water. Otherwise, the water around a reactor would become too radioactive and the people working inside the reactor building would inhale too much radiation for their safety. 

Some reactors use deuterium oxide, which is also called heavy water. Heavy water is 11% denser than normal water and all by itself, it is not radioactive. But this heavy water can still react with the same neutrons coming out of a reactor core, and in the manner as above, a reactor surrounded by heavy water still creates tritium, which is radioactive hydrogen.

Deuterium is hydrogen-2. Tritium is radioactive, hydrogen-3. Ordinary water is a better neutron shielder than heavy water. Depending on what a nuclear reactor is burning, the nuclear operators use may use a specific type of water to either slow the reaction down, (normal water) or speed up the reaction, (heavy water), such as in reactors that use unenriched uranium for fuel.

This same radioactive hydrogen (Tritium) is then released into the environment. Radioactive tritium is released as a normal part of operations from ALL nuclear power plants, recycling facilities, etc.

100% of all nuclear plants have contaminated the drinking water supply in their community with radioactive Tritium, via either plant emissions/leaks, and/or the air downwind of nuclear plants which contains this invisible radiation.
