Loyal guards kill anthrax bacteria
Anthrax shocked the world after the "9. 11" incident.
Why is anthrax so terrible? Experts explained that the anthrax spores spread to form, that almost no life spores hidden in the mail, winter or heat has no effect on them, are quietly waiting for the timing of spore, once people contact, they will become deadly bacteria.

In order to kill anthrax, a self shielded electron beam radiation accelerator has been developed in china. The accelerator electron gun emits electromagnetic waves of high power, when the conveyor belt is irradiated by high energy electron curtain items radiation zone, biological bacteria will be radiation in articles were all killed, after the mail and articles are not any residual radioactivity.

In recent years, as the main way of international freight, container transportation brings convenience at the same time, can also be used to some criminals smuggled goods, drug trafficking, smuggling of weapons and explosives. Using the cobalt -60 container inspection system, the smuggled goods, drugs, weapons and explosives hidden in the containers can be clearly displayed on the screen, thus effectively combating smuggling activities.
Tracer technique; understanding changes that cannot be seen or touched
Related parties, the use of radioactive isotopes as tracers, can understand some physical and chemical changes cannot be seen, touched, played an important role in the field of chemical industry, petroleum, water conservancy etc..
More than 90% of China's oil is water injection and oil production, after years of mining, water flooding serious. In order to better tap the potential of old oil field, researchers have developed a barium -131 radioactive tracer microsphere, which provides an effective tool for measuring injectivity profile of water injection well.
Well, the positioning release release of radioactive tracer microspheres has certain activity in the underground, tracer microspheres into the ground surface with different permeability with water, forming the diffusion layer of uniform flow, where, where with microspheres emit radiation signals, then, with the detector along the injection of radioactive measurement, can understand the injection and role in the formation and distribution of flow, providing a scientific basis for reasonable exploitation of oilfield and comprehensive management.

Dredging in China each year to spend tens of millions of yuan for the Yangtze River estuary sediment, in order to understand the operation of the law of sediment, Nanjing Academy on -46 with SC isotope in the upper reaches of the Yangtze River sand, then were observed with a scintillation detector, provides important technical data for the construction of governance of the Yangtze Estuary Deepwater Channel and all-weather deep-water channel. By using this technology after management, one hundred thousand tons of cargo ships through the mouth of the Yangtze River to the Shanghai Baoshan steel pier.
Ji'nan famous "Baotu Spring", but at the end of the 80s, the natural wonders of the spewing disappear. The isotopic tracer method has preliminarily made clear the state of groundwater in the Baotu Spring group, the source of supply and the law of operation, thus providing a scientific basis for the spring water supply in Ji'nan.
China's total amount of irradiated food ranks first in the world
Agricultural nuclear technology is one of the important fields in the development of modern agricultural science and technology.
Food irradiation processing technology is a new food processing technology after food storage, storage, heating and freezing preservation.

Since 1984, China began to potatoes, onions, garlic, irradiated sweet potato wine and meat products. At present, the country has 28 provinces, municipalities and autonomous regions, more than 200 units of 200 kinds of food were irradiation preservation and sterilization, improve the quality of the country has approved 18 kinds of irradiated food market, annual food irradiation reached a total of 100 thousand tons, ranking first in the world.
Insect radiation sterility technology is a harmless biological control new technology. The researchers used -60 cobalt cesium electron beam emitted by -137 gamma rays or accelerators, the pest insect pupa or adults to a certain dose of irradiation, the loss of male reproductive function, thus it can destroy die without descendants, pests and no pollution.

For five years, micro reactor researchers and CCTV, Qing Xiling and Beijing forensic medical examination center, the common use of micro reactor neutron activation analysis technology to test the content of arsenic in the relics of Emperor Guangxu braids, and combined with other techniques, unlock the mystery of hundred years.

The discovery of the site of the ape man in Zhoukoudian, Beijing, is a major event in the history of world anthropological studies, but there has been a lot of controversy about its age. In 1978, using solid state nuclear track detector method, ash layer measurement ape hole tenth layer "they left in sphene uranium -238 spontaneous fission track, made Beijing man 462 thousand years survival in conclusion, has been recognized the world.
