By using the models of tumor blood-borne metastasis and spontaneous one,the antitumor metastasis effect of 75mGy X-ray whole body irradiation on tumor bearing m
ZrO2 films on NaCl(100) substrate produced by oxygen ion bombardment and argon ion sputtering of Zr are analysed using TEM,XRD and XPS.The result of TEM shows t
The early risk of internal contaminated accumualtion of ^147Pm is in blood cells and endothelial cells,especially in red blood cells.Then ^147Pm is selectively
Radionuclides^186,188Re,suitable for tumor therapy and with high specific activity,are prepared through irradiating natural metallic rhenium,instead of costly e
Either sublinear or supralinear responses of dosimeters to γ-ray can be described by a response function derived from statistical Poisson distribution.The char
The dose-response curves obtained by premature condensed chromosome(PCC) and conventional cellular genetic methods can be represented by two linear equations.Th
The present work has dealt extensively and systematically with the fading characteristics of polystyrene-alanine dosimeters irradiated at different dose rates a
