X-ray irradiated from a Crookes tube that has a low energy of below 20keV cannot evaluate an effective dose by a common survey meter. However, intensity was very strong. In order to enable dosage evaluation at the school education field, the simple low energy X-rays evaluation technique using GM survey meter and cloud chamber was developed.
