Simulation of an imaging system for internal contamination of lungs using MPA-MURA coded aperture collimator
Ting Zhang, Lei Wang, Jing Ning +4
The nuclides inhaled during nuclear accidents usually cause internal contamination of the lungs with low activity. Although a parallel-hole imaging system, which is widely used in…
Unfolding the Neutron Spectra from a Water-Pumping-Injection Multi-layered Concentric Sphere Neutron Spectrometer Using a Self-Adaptive Differential Evolution Algorithm
Rui Li, Jianbo Yang, Xianguo Tuo +2
A self-adaptive differential evolution neutron spectrum unfolding algorithm (SDENUA) was established in this paper to unfold the neutron spectra obtained from a Water-pumping-injec…
Research on Fitness Function of Two Evolution Algorithms Used for Neutron Spectrum Unfolding
Rui Li, Jianbo Yang, Xianguo Tuo +1
When evolution algorithms are used to unfold the neutron energy spectrum, fitness function design is an important fundamental work for evaluating the quality of the solution, but i…
Bare and Polymer Coated Iron Oxide Superparamagnetic Nanoparticles for Effective Removal of U (VI) from Acidic and Neutral Aqueous Medium
Shan Zhu, Yangchun Leng, Minhao Yan +9
Superparamagnetic γ-Fe2O3 nanoparticles (5 nm diameter) were synthesized in water. The bare particles exhibit good colloidal stability at ~ pH 2 because of the strong electrostatic…
