Abstract：The radiation equipment for air-kerma primary standard in the range of low-energy X-rays is established.The results of experiment show that the diameter of the radiation field is more than 40 mm within 1% non-uniformity.The distance from the source to the reference plane is 1 000 mm.Radiation qualities recommend by CCRI are established.The half value layer(HVL)and the homogeneity coefficient are obtained by measuring the curve of x-rays attenuation.This low-energy X-rays radiation equipment and research results are the important base of establishing primary standard,realization of air-kerma and the APMP key comparison in the range of low-energy X-rays(APMP.RI(I)-K2).
