American scientists have developed a cost-effective radiation monitoring detector

It is reported that a new, cost-effective radiation monitoring and detection instrument has been developed by the School of Engineering of The Ohio State University in the United States. Its cost will be lower than that of previous products. At the same time, the instrument can detect the level of radioactive contamination in the nuclear environment more accurately. , And has excellent detection speed.

At present, this new radiation spectrometer has been patented and the first products will be available soon. New technology also brings new business to Avicenna Equipment. The Ohio-based company will rely on research technology from Ohio State University to produce related parts. Relevant researchers said that this radiation spectrometer will eventually be promoted to the world, the relevant industries around the world can use this new technology.

It is reported that the annual cost of processing nuclear radiation-contaminated areas amounts to several hundred million US dollars. This is mainly the historical pollution left over from the production of nuclear weapons before and after World War II. These areas include the Hanford Atomic Energy Research Center in Washington State, the nuclear waste site in the Savannah River District in South Carolina, and the Oak Ridge National Laboratory in Tennessee.

David Hamble, a professor of radiation protection at Ohio State University, said that the new spectrometer will be more efficient than previous detectors. It can detect and quantify gamma rays and beta radiation simultaneously. In order to detect both rays at the same time, there must be two different detection instruments and other chemical tests, which is a time-consuming process. "The new device can give accurate results to the test object in 15 minutes. In the past, this process took half a day. The new device not only simplifies the process, but also saves time and money."

The new spectrometer is the result of 10 years of research by David Habib and Abby Fossini, an associate professor at Ohio State University’s School of Engineering. The new spectrometer can quickly identify the type and amount of radionuclides contained in the test article. Through the detection of soil samples, the spectrometer showed that the soil samples contained contaminants such as cesium 137 and helium 90, which were produced from nuclear reactors. In addition, spectrometers can distinguish between gamma rays and beta particles, which is a necessary part of identifying pollution levels.

David Happi said: "We can also eliminate nuclear radiation pollutants, but this process is very expensive, and people in our field will ask this question, this so-called 'clear' can do more Thoroughly, therefore, we should do everything we can to increase research and development, and often to conduct precision tests, and we should also think of ways to control costs, all of which are conducive to our protection of the environment."

David Hamber said that this system can eventually be used to detect the radiation situation in the nuclear industry, but also can be applied to the radioactive tracking research in the medical community.

The Ohio State University School of Engineering has signed a contract with Ludlum Equipment Corporation of Texas to produce the first batch of equipment. The Ohio State University Technology Transfer Office also hopes to obtain a license for commercial development purposes. In addition, the spectrometer's electronic system will be produced by Avicenna.
