Scientists can now PROVE if nuclear bombs have been properly dismantled by a & # 39; neutron beam & # 39; shoot at the warhead to search for plutonium

  • Plutonium isotopes are unique and were used in the bombing of Hiroshima
  • Many countries are going through a process of giving up their nuclear weapons
  • But it is impossible to prove that these warheads were taken completely offline
  • Researchers have created a way to test a warhead to see if it is active without giving away confidential military secrets

Scientists believe they have created a way to detect whether a warhead has been successfully deactivated.

It is currently almost impossible to see if the weapon itself has been dismantled.

Experts from the Massachusetts Institute of Technology (MIT) have created a neutron beam that detects the significant presence of a specific type of plutonium in weapons.

Nuclear warheads have a distinctive material layout and the giveaway presence of the plutonium responsible for the destructive power of the weapon.

Experts say that this detection method to prove whether bombs have been dismantled can be used to ensure that countries do not secretly stock nuclear weapons.

HOW ARE NUCLEAR TREES TESTED TO ENSURE THAT THEY ARE UNASSEMBLED?

According to current guidelines and with existing technologies, weapon inspectors rarely know when a warhead has been dismantled.

Inspectors rarely get full access to arsenals due to concerns about military secrets.

During military treaties, to keep both parties happy, countries are willing to prove that they have destroyed the weapons.

But the destruction often has to do with delivery systems (such as rockets or planes) and not with the warheads themselves.

For example, the US cut off the wings of B-52 bombers and left them in the Arizona desert, where Russia could visually confirm the disintegration of the planes.

But the warheads, where most of the damage has been done and the plutonium has been stored, can still be active and await detonation.

There is currently no independent way to detect whether or not they have been dismantled.

& # 39; There is a real need to prevent this kind of dangerous scenario and to go after these stocks & # 39 ;, says Areg Danagoulian, a nuclear scientist from MIT. & # 39; And that really means a verified dismantling of the weapons themselves. & # 39;

Stored warheads that have not been properly dismantled can be extremely dangerous if they are sold, stolen or accidentally exploded.

& # 39; There is a real need to prevent and go after these types of dangerous scenarios & # 39; s, said Areg Danagoulian, a nuclear scientist from MIT who led the project.

& # 39; And that really means a verified dismantling of the weapons themselves. & # 39;

The method developed to stop these problems uses what researchers call an isotopic filter to physically encode the information excavated in the analysis.

& # 39; This encoding filter essentially covers the intrinsic properties of the actual classified object itself & # 39 ;, Dr. Danagoulian explains.

The experiments that led to the breakthrough concerned the sending of a horizontal neutron beam through a warhead.

To prevent the use of the very limited plutonium, researchers chose to use molybdenum and tungsten substitutes because they behave the same way.

The signal from the beam is sent to a glass detector, where the data is recorded.

The test works because the neutron beam can identify the relevant isotope.

& # 39; At the low energy range, the interactions of the neutrons are extremely isotope-specific & # 39 ;, says Dr. Danagoulian.

An isotope is a variation of the normal state of an element and can become unstable due to the presence of different amounts of neutrons.

& # 39; So you do a measurement where you have an isotopic label, a signal that itself encloses information about the isotopes and the geometry.

& # 39; But you take an extra step that physically encrypts it. & # 39;

The encryption process saves the data, but modifies some precise data to protect any military secrets while the weapon is revealed.

This is crucial to get countries on board to volunteer for testing, the researchers say.

& # 39; This encoding filter essentially covers the intrinsic properties of the actual classified object itself & # 39 ;, Dr. Danagoulian explains.

They chose to change the physical data themselves, because the use of the laws of physics as a coding method is more robust than that of the computer, which can be fooled and fooled by hackers.

Dr. Danagoulian notes: & # 39; You could basically do it with computers, but computers are unreliable. They can be hacked, while the laws of nature are unchangeable. & # 39;

Researchers tested the coding to ensure that the process could not be reverse-engineered to undo the protection and unravel the military secrets of another country.

His prototype is currently (15 meters) long and in the future Dr. Danagoulian wants to miniaturize the device and install one at all weapon locations.

The researchers published their findings in the journal Nature Communications and say that many more protocols are needed to support the technology.

WHAT HAPPENED IN THE BOMBING OF HIROSHIMA AND NAGASAKI?

The first atomic bomb was dropped on the Japanese city of Hiroshima on August 6, 1945 by an American B-29 bomber named the Enola Gay.

The 9,000 pound uranium-235 bomb exploded 1,900 feet (580 meters) above the ground, killing between 60,000 and 80,000 people immediately, some immediately disappearing from the heat of the massive explosion.

Others died when the fire tore through the city and an estimated 135,000 people died from radiation sickness.

The blast flattened more than six square miles (10 square km) of the city, with fires burning for three days, leaving thousands of survivors burned and homeless.

With large buildings such as hospitals destroyed and more than 90 percent of the city's doctors and nurses killed in the explosion, little help was available for the wounded.

Three days later, a second American atomic bomb killed 70,000 people in Nagasaki.

Japan surrendered six days later and ended the Second World War.

Ten years later, the long-term effects of the bombs were noted, including an increase in leukemia – a blood cancer that was not included in the study.

It is said that the cancer affects children disproportionately, with cases appearing two years after the bomb and peaking four to six years later. IBT reported.

The Radiation Effects Research Foundation estimates that 46 percent of leukemia deaths at the bomb sites from 1950 to 2000 were due to radiation from the bombs, with a total of 1,900 deaths from cancer associated with the atomic bomb.
