我们利用一台GTY—200—20型工业X射线机,建立了6—80keV的K荧光X射线源和40—160keV连续过滤X射线源。为了能实施对所形成的X射线辐射场进行照射量率的绝对测量,我们建立了适用于能区在30—130kV的自由空气电离室和它的电测装置。
We use a GTY-200-20 industrial X-ray machine, the establishment of 6-80keV K-fluorescent X-ray source and 40-160keV continuous filtered X-ray source. In order to carry out the absolute measurement of the radiation dose rate of the formed X-ray radiation field, we have established a free air ionization chamber with an energy range of 30-130 kV and its electrical measuring device.
