In order to explore whether radon anomaly could be considered the precursor of rock slide, the forming mechanism of the radon anomaly is qualitatively analysed
Red and white guavas were treated with wax emulsion or irradiation (0.25-2.0 kGy) and kept for 12 days at room temperature. Initiation of rot attack occurred af
With the method of Rutherford backscattering of heavy ions from heavy substrate, the stopping powers of 11B, 12C and 19F in silver film were measured at energie
Na211 At and 211 At-Te colloid injections are prepared. It has been demonstrated that the 211 At-Te colloid is stable in vivo and vitro, and can be applied in t
Biological materials of garlic, Wulong-tea and human hair were investigated by 14.2 MeV proton activation analysis using internal standard method. Elemental con
In this paper Al2O3 and MgO were studied as targets for the radiation grafting of MAA by electron beams. The reaction conditions and materials were characterize
The theoretical prophecy is given on a new chiral allotrope of Fullerene-C80.C80 molecuule should have 3C2 symmetric axes,which should be vertical each othyer.C
Magnetic anisotropies and hyperfine fields of amorphous a-Fe-(Co, Cr)-Zr alloys, their temperature and thermal stress effects were studied by using a Mossbauer
In recent years the extrapolation chamber has been developed a clinical dosimeter for electron beams and X-rays from medical linac. It consists of a new type ex
The properties of α-Fe2O3 fine particles with and without adsorbed pyridine were studied by Mossbauer spectra. The effective anisotropy constant K were calcula
