We employ molecular flow methods to numerically simulate the supersonic nanoparticles in free-molecule regime. To streamline computational complexity, interaction forces between gas and solid particles are disregarded. first develop a discrete phase model (DPM) method that integrates non-rigid body collision model, enabling an accurate simulation of nanoparticle diffusion under influence drag force Brownian motion force. The considered this study have sizes below 10 nm, accuracy DPM is...
In order to address the issue of limited detection range in traditional <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$a$</tex> radiation detectors, a system based on UVtron R13192 flame detector and custom-designed driving circuit was developed. Signal checking, pulse characteristic testing, background radioactive source measurements were performed. The experimental results compared with findings Crompton et al., activity response curves our...
An online monitoring technology of Pu-239 aerosol based on direct introduction device, membrane desolvation nebuliser and ICP-MS was established for workplaces reprocessing plants. Briefly, 0.8 l min-1 from the workplace introduced into device where air replaced by Argon, then measurement. To determine activity aerosol, 1.10E-3 Bq ml-1 Pu-242 standard solution generated a used. The efficiency determined sampling with Lead Standard Solution glass fiber filter, which (26.82 ± 3.33) %. mass...
The concentration of 210Po in the desulfurized waste water can be affected by operation wet desulfurization system coal fired power plant (CFP). However, this correlation is poorly studied and documented current literature. aim study was to report level from a CFP using system. average samples measured 2.4 ± 0.3E-3 Bq/L, 4 times higher than our control (sea water), which 6.1 1.4 E-04 Bq/L. annual total discharge estimated 7.03 × 108 Bq/GWa, much release air stack modern CFP.
Low-energy radiation is primarily involved in the spent fuel treatment process a specific nuclear facility, but if it not shielded, will still have an impact on worker health. In light of this unique low-energy environment, Monte Carlo simulation software geant4 used to simulate and calculate effect doping many rare earth elements into glove rubber materials shielding gamma radiation. The results show that some good effect, their chemical toxicity lower than traditional material lead. This...
Objective To study the protection of vanillin derivative VND3207 on cytogenetic damage mouse bone marrow cell induced by ionizing radiation.Methods BALB/c mice were randomly divided into five groups:normal control group,2 Gy dose irradiation group,and three groups 2 irradiaiton with at doses 10,50 and 100 mg/kg,respectively.VND3207 was given intragastric administration once a day for days.Two hours after last drug administration,the irradiated γ-rays.The changes polychromatophilic...
