发明名称 Radiation measuring device for measuring doses from a radiotherapy aparatus
摘要 A radiation monitor has an ionization space formed with a frame made of insulating material, a high-voltage electrode, and a collecting electrode opposing the high-voltage electrode. The ionization space has an equal dimension throughout the passage of a radiation. Therefore, the Boyle-Charles' law applies almost perfectly to the ionization space. Thus, an ionization current can be extracted without the influence of an ambient pressure or temperature.
