Hualong, high temperature gas cooled reactor, no. 1 small heap, is known as the "nuclear field of heavy industry" in addition to nuclear, launched in 14 "China - green theme nuclear science activity" exhibition, "light" in the field of nuclear - nuclear technology also noteworthy.
The event by the Chinese association for science and technology, national energy administration, national atomic energy agency (iaea), the national nuclear safety administration joint nuclear enterprises, local association for science and technology, such as joint, in the following one month, the public can be free to China science and technology museum, feelings of nuclear technology in the field of industry, agriculture, medicine and so on.
The loyal guard kills the anthrax bacteria
After the Sept. 11 incident, anthrax shocked the world.
Why is anthrax so terrible?
Experts said, anthrax spores form, who almost lifeless spores hidden in mail, winter or summer doesn't work on them, the spores are in wait quietly, once out of the reach of most people, they will become a deadly germs.
In order to kill anthrax bacteria, our country developed self-shielded electron beam radiation sterilization accelerator.
Accelerator gun emit high power electromagnetic wave, when the conveyor belt after high energy electron shade radiative zone by irradiation items, all items of biological bacteria by radiation can be killed, after processing of mail and goods will not remain any radioactive.
Tracer technology understands invisible, intangible changes
Relevant personage introduces, using radioactive isotope as a tracer, can understand people see or touch some of the physical change and chemical change, in many fields such as chemical industry, petroleum, water conservancy, played an important role.
More than 90 percent of the oil fields in China are waterflood oil production. After years of exploitation, water flooding is generally serious.
In order to better excavate the potential of old oilfield, the researchers developed a barium -131 radioactive tracer microsphere, which provides an effective tool for the determination of water injection profile.
Logging, using positioning release, have certain activity in downhole release of radioactive tracer microspheres, tracer microspheres with water injection into the surface of different permeability, the formation of uniform diffusion layer, where the water, where microspheres was with a radiation signals, then, along with the detector injection Wells for radioactive measurement, can understand water distribution and flow to and function of in formation, to the reasonable development of oilfield and offer a scientific basis for comprehensive control.
In our country every year to spend tens of millions of dollars in Yangtze estuary sediment dredging, to understand the running law of sediment, nanjing iwhr containing scandium - 46 isotopes in the Yangtze river upstream of quartz sand, and then followed by scintillation detector, for Yangtze estuary deepwater channel governance and the construction of the deep navigation channel in the all-weather provides important technical data, after adopting the technology treatment, one hundred thousand tons of cargo terminal through the Yangtze estuary reach Shanghai baoshan steel plant.
The "baotu spring" in jinan is famous and famous at home and abroad, but in the late 1980s, the natural spewing wonders disappeared.
The isotopic tracer method preliminarily understands the state, supply source and operation law of the groundwater in baotu spring, which provides the scientific basis for the water supply of jinan baoquan.
The total annual irradiation food in China ranks first in the world
Agricultural nuclear technology is one of the important fields of modern agricultural science and technology development.
Food irradiation processing technology is a new food processing technology after the technology of heating and freezing preservation.
Since 1984, China has started irradiating garlic, potatoes, Onions, sweet potato and meat products.
Currently 28 provinces, municipalities and autonomous regions across the country had been more than 200 units have been conducted for more than 200 kinds of food irradiation preservation, insecticidal sterilization, improve the quality of research, countries approved 18 kinds of irradiated food, food irradiation totaled 100000 tons, the first in the world.
Insect radiation sterility technology is a new technology of biological control.
Researchers using cobalt 60, cesium - 137 and emit gamma rays or electron beam accelerators, the pest insect pupa and adult dose irradiation, lose their male reproductive function, it can destroy pests and does not produce pollution.
