This work firstly prepares the material by microemulsion polymerization. The ability of anti-radiation, transmittance ratio and glass transition temperature (Tg) of the material was characterized. The anti-radiation ability is enhanced with the increasing of lead salt content and the thickness of the material. The transmittance ratio decreased with the content of the lead salt. The glass transition temperature of the material is increased with the lead salt content of the organic glass. 展开更多

With the development of anti-radiation weapons,the effectiveness evaluation of anti-radiation weapons has been turned from the simple accuracy index to the integrated countermeasure capability.The research priority is how to access the combat effectiveness of anti-radiation weapons in a complex countermeasure environment.For the present situation of range test of anti-radiation weapons,a combat effectiveness assessment model based on non-linear index aggregation is proposed for anti-radiation weapons.And the corresponding index system model,index aggregation methods,index marking method and index weight determination are given.Finally,the simulation results verify the efficiency and feasibility of the proposed method. 展开更多

Aiming at the harmfulness of and protection from ionizing radiation, this paper will centre on the design and synthesis technology of a new type of polymeric material which is stable at the ionizing radiation from 10-11 to 10-8 meter wave. The material is made up of epoxy resin 6101, curing agent phenolic-aniline resin, which is developed by the authors, and other auxilliary agents. This material is stable at the radiation of 107Gy,and its physical and chemical properties are excellent. 展开更多

Crosslinked poly(methyl methacrylate) and polystyrene with barium dimethacrylate [Ba(MA)_2] as crosslinking agent have been synthesized. The relationship between X-ray absorbability and the content of Ba(MA)_2 in polymers was investigated. TGA and DSC results indicated that the crosslinked polymers containing barium dimethacrylate have a much better heat stability than pure PMMA or PS. The mechanical properties of the polymers containing barium are improved in comparison with the pure PMMA. 展开更多

An anti-radiation structure of In P-based high electron mobility transistor(HEMT) has been proposed and optimized with double Si-doped planes. The additional Si-doped plane under channel layer has made a huge promotion in channel current, transconductance, current gain cut-off frequency, and maximum oscillation frequency of In P-based HEMTs. Moreover, direct current(DC) and radio frequency(RF) characteristic properties and their reduction rates have been compared in detail between single Si-doped and double Si-doped structures after 75-keV proton irradiation with dose of 5× 10^(11) cm^(-2),1× 10^(12) cm^(-2), and 5× 10^(12) cm^(-2). DC and RF characteristics for both structures are observed to decrease gradually as irradiation dose rises, which particularly show a drastic drop at dose of 5× 10^(12) cm^(-2). Besides, characteristic degradation degree of the double Si-doped structure is significantly lower than that of the single Si-doped structure, especially at large proton irradiation dose. The enhancement of proton radiation tolerance by the insertion of another Si-doped plane could be accounted for the tremendously increased native carriers, which are bound to weaken substantially the carrier removal effect by irradiation-induced defects. 展开更多

We demonstrate the spectroscopic and laser performance before and after 100 Mrad gamma-ray irradiation on an Er,Pr:GYSGG crystal grown by the Czochralski method. The additional absorption of Er,Pr:GYSGG crystal is close to zero in the 968 nm pumping and 2.7-3 μm laser wavelength regions. The lifetimes of the upper and lower levels show faint decreases after gamma-ray irradiation. The maximum output powers of 542 and 526 mW with the slope efficiencies of 17.7% and 17.0% are obtained, respectively, on the GYSGG/Er,Pr:GYSGG composite crystal before and after the gammaray irradiation. These results suggest that Er,Pr:GYSGG crystal as a laser gain medium possesses a distinguished antiradiation ability for application in space and radiant environments. 展开更多

Objective:To explore the effect of Renshen Yangrong Decoction(人参养荣汤,RYD) in protecting bone marrow from radiation injury.Methods:One hundred and eighty Kuming mice were subjected to the three tests for anti-radiation injury effect evaluation,i.e.the test of peripheral white blood cell(WBC) count, the test of bone marrow nucleated cell count,and the bone marrow micronucleus test,using 60 mice for each test.The mice in each test were divided into 6 groups:the blank control group,the model control group,the positive control group treated by Shiyiwei Shenqi Tablet(十一味参芪片,1.0 g/kg),and three RYD groups treated with high(42.0 g/kg),moderate(21.0 g/kg),and low(10.5 g/kg) doses of crude drugs of RYD,with 10 mice in each group.The treatment was given by gastrogavage perfusion continuously for 7-14 days before mice received ^(60)Co-γray radiation and continued until the end of the experiment.The body weights of the mice were monitored,the changes in peripheral WBC and bone marrow nucleated cells were counted,and the variation in bone marrow micronucleated cells was observed on the respective appointed days.Results:A significant decrease in body weight,peripheral WBC count,and bone marrow nucleated cell count,as well as marked changes in bone marrow micronucleated cells were observed in the mice after radiation,indicating that the radiation injury model was successfully established.As compared with the model control group,the decrease in body weight,peripheral WBC count,and bone marrow nucleated cell count,as well as the increase in bone marrow micronucleus cell count in the high dosage RYD treated group were obviously inhibited or lessened (P0.05 or P0.01).Conclusion:RYD showed obvious protective effect in mice with bone marrow injury induced by radiation. 展开更多
