Abstract
In order to provide a high accuracy radiation dose rate measurement system by good energy characteristics without deteriorating the original energy characteristics of a low dose rate range due to widening range, the dose rate measurement system is composed of: a radiation detector which sends a discrete current pulse having electric charge proportional to incident radiation energy and a DC voltage in which a DC current proportional to the radiation energy is converted; a high voltage power source which supplies a high voltage that operates the radiation detector; and a measurement unit in which the current pulse and the DC voltage are applied from the radiation detector to be converted to a low range dose rate and a high range dose rate respectively, and the low range dose rate and the high range dose rate are switched to be sent depending on the dose rates.
