| Outline of Final Research Achievements |
The purpose of this work is that development and application of an infrared light-emitting scintillator by alpha particles for biologists to study a response to the irradiation of a cell with a conventional device used in bio-lab as a target. This new method enables the biologist to do an in situ experiment on the radiation influence for the cell.
We have developed the device with a micro alpha-source (Po-210) on XY-stage controlled by stepping motors that can set the irradiation at a position desired by the user. The number and the position of irradiated alpha particles have been controlled by using devices of the silicon detector and the infrared PSD. The source position which are controlled by the XY-stage PC, and the detecting single of alpha particles have been successfully developed in the individual components for the final system.
