Scientists from the state University of stereotypes and technology (NIST) have released landmark test results that hope, in fact, that a promising class of sensors has the ability to be applied in the criteria of the highest radiation and to promote significant honey, industrial and research applications.

Photonic detectors transmit information by light, not by electronic currents in the wires. They have every chance to measure, transmit and manipulate photon jets, acceptable through glass fibers, and used for such in order to calibrate the pressure, temperature, distance, magnetic fields, the circumstances around the environment and more.

They are presentable because of their small volume, low power consumption and tolerance related to the environment around the variables as automatically ripple. But the only consideration was that the highest values of radiation will change the optical quality of silicon, in fact that will lead to incorrect evidence.

As a result, NIST, a long-time universal favorite in many areas of Photonics research, launched a program to answer these questions. The results of the test demonstrate that in fact the detectors were able to be customized to measure radiation dose in industrial applications, e.g. in medical therapy. The results of his first round of testing are reported in full-scale scientific reports.

In particular, the results of NIST hope, in fact, that the detectors have every chance to be used to track the values of ionizing radiation (with the energy necessary for the configuration of the structure of atoms), used in the irradiation of food products for the elimination of bacteria and in the sterilization of honey devices-it is estimated that every year market in the USA Detectors still have probable use in medical imaging and therapy, which together, according to monitoring, will amount to almost $ 50 billion a year worldwide by 2022.

"When we looked at the publications on this issue, the different laboratories received completely different results,"said plan scientist Zeeshan Ahmed, who is considered part of the NIST photon dosimetry plan and the Manager of the NIST photon thermometry plan. "It was our key motivation for the experience."

"Another prerequisite was the increasing attention to the deployment of photon sensors, which have all the chances to literally work in quite formidable criteria, these as close to nuclear reactors, where radiation damage is considered a serious problem," said Ahmed. "Apart from this, the galactic industry obliged the aristocracy, as these device will work in the criteria of the higher radiation",-said the scientist plan Ronald Tosh. "Will they be damaged or not? This study demonstrates that for a particular class of devices and radiation damage is negligible."

"We have noticed that silicon oxide photons have all the chances to withstand the radiation effect up to 1 million gray," said Ryan Fitzgerald, the head of the photon dosimetry plan, using the SI unit for the absorbed radiation. Once the grayish paint corresponds to 1 Joule of energy absorbed by a kilogram of mass, and once the grayish corresponds to 10,000 chest x-rays. This is approximately what the sensor will receive at the nuclear power plant.

"This is the upper limit of what our calibration buyers are actually worried about," said Fitzgerald. "In this way, it is possible to imagine that the device itself is working hard at industrial or honey radiation levels, which are a hundred or one thousand below."Irradiation of food products, for example, ranges from several hundred to several thousand grayish, and, as a rule, is controlled by its action on the granules of alanine, an amino acid that changes its own atomic qualities when exposed to ionizing radiation.

In order to qualify the effects of radiation, NIST scientists were influenced by 2-faces silicon photon sensors gamma radiation of cobalt-60, a radioactive isotope, in the direction of several hours. In both types of sensors, the little configurations in their bodily properties alter the wavelength of light that travels through them. By the method of measuring those configurations, the devices can be applied as highly sensitive temperature pointers or strain gauges. This remains correct in extreme criteria, such as galactic flights or nuclear reactors, only if they continue to operate in a suitable manner under the influence of ionizing radiation.

"Our results demonstrate that these photonic devices are stable, including in extreme radiation environments, which actually implies that they have all the chances to still be used to measure radiation through its impact on the physiological qualities of irradiated devices," said Fitzgerald. "This should freeze with good news for a South American manufacturer that is eager to serve a tremendous and growing Bazaar for a clear delivery of radiation on a fairly small scale. Photonic detectors were subsequently able to be developed for this in order to measure the low-energy rays of the electron and x-ray used in sterilization and irradiation of food medical service."

They will still be of great importance for medical medicine, in which doctors want to treat cancer and other diseases with a minimum effective level of radiation, aimed at smaller dimensions, in order to avoid the impact on healthy tissues, covering electric, proton and ion beams. Achieving this goal is asking for radiation with very high sensitivity and spatial resolution. "The end result we are trusted to create a smart device for industrial and medical use, which will be able to predetermine the gradient of the absorbed dose at distances in the range of micrometers and, this way, ensure that the unprecedented detail of measurements", the scientist said plan Nikolay Klimov. A micrometer is a millionth of a meter. Human hair draws in the range of 100 micrometers.

The results of the team have every chance to own a tremendous sense for fresh honey healing methods that use very narrow beams of protons or carbon ions and honey sterilization processes that benefit low-energy electron beams. "Our detectors are small and chip, of course," Fitzgerald said. "Modern dosimeters have dimensions from mm to centimeters, which actually has the ability to lead to incorrect evidence for fields that vary depending on the data volumes."

At the proper turn of the studies, the group will test arrays of sensors in similar criteria at the same time to see if it is possible to allow dose options at short distances.
