The Particle Analysis Based on FT-TIMS Techinque for Swipe Sample Under the Frame of Nuclear Safeguard

Under the frame of nuclear safegurd,the particles analysis for swipe sample is an advance mean to detect the undeclared uranium enriched facilities and undeclared uranium enriched activity.The technique of particle analysis based on fission tracke-thermal ionzition mass spectrometry(FT-TIMS)for swipe sample have been builded.The reliability and the expermental background for selecting partiles consisting of uranium from swipe sample by FT method have been verified.In addition,the utilization coefficienct of particles on the surface of swipe sample have also been tested.These works have provided the techique surpport for application in the area of nuclear verification.
