A new tool developed by Israeli scientists shows that radioactive material that was left behind after the 2011 earthquake and tsunami at the Fukushima Dai-ichi nuclear plant in Japan was at least 20 times denser than previously thought.
The new technique, described in a paper published in the journal Applied Physics Letters, used an advanced, high-speed X-ray imaging system to measure radioactive material released from the reactor site after the March 2011 earthquake.
The new technique also shows that most of the radioactive material was still present in the area more than three years after the quake.
“The most important thing is that the radiation from the quake and tsunami was not removed.
It was retained,” said Yona Schachter, a doctoral candidate at the Hebrew University in Jerusalem and the lead author of the paper.
“That’s important because, even if we remove a lot of the debris, we still have radioactive material left behind.
And if we don’t remove it, the radiation can continue to get to the soil and groundwater.
So, removing it is very important to prevent this from happening again.”
The new technology is a step toward identifying the source of the remaining radioactive material, which has been attributed to the meltdown of a nuclear reactor that went out of operation in 2011.
In 2013, the U.S. National Nuclear Security Administration, which is part of the U:National Nuclear Security Agency, announced that it had identified a potential source of radiation that was in the reactor.
The agency concluded that this was “possibly the result of an earthquake or an explosion that triggered a tsunami or an earthquake.”
The agency said the tsunami and earthquake could have caused the reactor to melt down, releasing large amounts of radioactive materials into the environment.
The radioactive material from the Fukushima plant was removed from the area by March 2012.
Since then, radioactive materials have been found at other nearby reactors and sites.
The technology Schachhertz developed was developed at the Institute for Nuclear Physics and Applied Materials, the Israel Atomic Energy Commission’s (IAEC) research and development agency.
The institute has long used X-rays to measure the density and density range of radioactive substances in the atmosphere.
The team used a highly sensitive X-Ray spectrometer to measure levels of radiation at the Daiichi power plant.
The spectrometers uses an advanced X-band spectromete, which can detect radioactive substances at wavelengths ranging from about 300 nanometers to 1,500 nanometers.
“Our X-axis is about 10 meters,” said Schachcher.
“We use the X-range, which was 10 meters, to measure radiation from nuclear fuel, which we are using here.”
The spectrometers measurements are accurate at a distance of about 300 meters.
Using this method, the team was able to measure nearly a meter of the contaminated soil around the site.
The scientists used an X-line that measured the X sensitivity.
This means that it takes about one nanosecond of exposure to a given wavelength to get an accurate measurement of the intensity of radiation emitted.
Using the sensitivity, the researchers were able to determine the amount of radioactive elements and isotopes.
The researchers used a laser to measure each element and the amount and type of isotopes in the soil.
A new technology developed by scientists from the Institute of Nuclear Physics at the IAEA is a new method to measure radionuclides and isotope levels.
The IAEAP is a partnership of the ICR and Israel Atomic Research Organization.
The Israeli researchers analyzed soil samples from a hilltop site near the plant and found a large amount of uranium and uranium-235, which are the main components of the isotope U-235.
This isotope is also used as the isotopes of radioactivity and is produced naturally in nuclear reactors.
Uranium is present in all living organisms, including plants, animals, and even humans.
U-233, the most abundant isotope of uranium, is present at high levels in the blood and brain of the Fukushima victims.
The isotope has been detected in the bodies of some Fukushima victims, including the head of the Dai-ji nuclear power facility, Tepco, and several members of the emergency committee.
“This isotope may be one of the key ingredients of the nuclear fuel,” said the lead researcher of the study, Prof. Yona Shachter.
“It is used as a fuel in the nuclear reactors at Fukushima, and it is also the isotopic source of a few other radioactive materials.”
The researchers also found traces of a highly radioactive isotope, known as U-232, in the water around the reactor complex.
Urea, a common isotope in seawater, also can contain U-231.
Urea is the primary constituent of a chemical compound that can be converted into U-238.
It is the main ingredient in a number of radioactive compounds, including plutonium and thorium.
The researchers found traces and amounts of U-241 in a portion of
