Description
Technical field
The invention belongs to safety check technical field, and in particular to a kind of safe examination system and its application, further relate to a kind of safety check side
Method.
Background technology
At present, core bioterrorism has constituted the significant threat to China or even world-wide safety.So-called coring is afraid to be afraid of, and is referred to
Terrorist is reaches the purposes such as its politics, economy, religion, nationality, by sensitive sites or densely populated place region, being directed to
Property discharge radioactive substance or biochemical weapon agent, cause a tremendous loss of lives, environmental pollution, seriously endanger national security and society
Stable extreme attack of terrorism behavior.Core bioterrorism has following features：One is disguised, and the incident of core bioterrorism is unexpected,
Time, place, harm source category, damaging range, the harm approach of incident etc. are indefinite, and this is targetedly taken precautions against and rescued
Help and bring extreme difficulties；Two be diversity, and the type of raid is various, and transmitting carrier is various (for example, it may be air, water source, mail
Deng)；Three be group, and core bioterrorism attacks can cause a tremendous loss of lives, and brings serious colony's sexual psychology panic, for example
Nineteen ninety-five Tokyo subway Schain poison gas event, causes 5500 people poisoning, causes serious society panic.
With the development of core biochemical technology, radioactive material, chemical toxicant, the difficulty relative reduction of biological poison are obtained,
These dangers are caused easily to be obtained and utilized by terrorist.Since 21 century, core bioterrorism has been presented
Go out to endanger source diversification, scope of activities globalization, implement means high-technicalization, the diversified trend of the type of raid.By having sent out
From the point of view of raw core bioterrorism attacks event, core bioterrorism send out by from " the low technology act of terrorism " to " the high-tech act of terrorism "
Exhibition, or even individual other terroristic organization are had been equipped with producing and the energy of mass destruction weapon are used as using military biochemical weapon agent
Power.From now on, the new paragon that core bioterrorism attacks will be used as extreme terrorism.
Although extensive core bioterrorism event not yet occurs at present for China, with the scattering and permeating of international terrorist activity
Increasingly sharpen, be in China among international environment and also face increasingly serious core bioterrorism and threaten.Core bioterrorism attacks
The inevitable mode that terroristic organization of the following country uses is would is that, therefore, takes precautions against and reply core bioterrorism attacks turns into guarantee
The vital task of national security.
Because core bioterrorism has disguised, group and multifarious feature, thus public place will turn into strick precaution
The place such as emphasis, especially station, airport, subway, harbour, customs port, Important building facility, should strengthen safety inspection, and
It is early to find Harm and control, timely reply processing, it is to avoid the generation of the attack of terrorism.
