Research for space radiation dosimeters using low energy proton beams in a global framework

点击翻译按钮获取中文摘要

Luminescence dosimeters which have been used by space agencies and universities in the world were gathered and irradiated by wide, uniform and low energy proton beams from the cyclotron accelerators with same conditions. After experiments, these dosimeters were analyzed by the international collaborators and these analysis results were compared each other. Then, these characteristics were investigated and understood, so that their reliability has been higher and it is important for dosimetry for astronauts and cosmonauts who will stay long periods.
