We are developing a radiation detector in the Sierpinski's tetrahedron shape, which is a fractal shape of self-similarity. The tetrahedral radiation sensor is a unit of 16 GAGG scintillators arranged in a Sierpinski tetrahedron shape and filled with heavy metal between the sensors. Although the total count rates of the 16 scintillators are almost the same for the incident direction, the count rates of the individual scintillators can be used to identify the incident direction of the radiation. In this presentation, we will report the results of the characteristic test and field measurement of the newly developed instrument based on the previous presentation at the AESJ conference.

In the decommissioning of the Fukushima Daiichi Nuclear Power Plant, non-destructive inspection of piping inside and outside the facility and inspection of contamination inside the piping after removal of the piping is an important issue. In order to set targets for nondestructive inspection inside the piping, we interviewed TEPCO and confirmed the following conditions: the diameters of pipes commonly used in the 1F facility (500A and 25A), hydrogen gas containing 
-ray emitting nuclides, deposits, and moisture inside the pipes. Based on this situation, the two major themes of the research design were nondestructive inspection for internal penetration and radiological imaging. In this series of presentations, we will introduce the research plan and some of the results related to radiation imaging.
