Ionizing radiation - medium energy x-ray beams
The latest results of the continuous comparison BIPM RI(I)-K2 have been published in the KCDB where recent comparison recults obtained for NIM (China) were included. This comparison is a series of bi-lateral comparisons of the determination of air kerma in medium energy x-ray beams. These radiation qualities are used for radiotherapy and applications in radiobiology.

Ionizing radiation - low energy x-ray beams
The latest results of the continuous comparison BIPM RI(I)-K1 have been published in the KCDB where recent comparison recults obtained for NPL (United Kingdom) were included. This comparison is a series of bi-lateral comparisons of the determination of air kerma in low energy x-ray beams. These radiation qualities are mainly used for imaging.
