Development of visualization technology for ionizing radiation放射線検出材料で作られた手の模型

Ionizing radiation has been widely used in the industrial and medical fields for decades, and advanced radiation technologies for medical imaging and radiation therapy are now available. However, it is generally impossible to observe ionization radiation with the naked eye. Thus, my coworkers and I have developed visualization technologies for ionizing radiation. The photograph below shows a hand phantom made of a radiation-sensitive resin. The radiation dose distribution in the hand phantom can be precisely estimated from the fluorescence intensity profile.
