“…For example, in the case of Fukushima, the visualization of the radioactive contamination by the gamma-ray imager is expected to accelerate the prioritization and verification processes of the decontamination. Based on recent development of high-quality room temperature semiconductor devices and readout analog ASICs, gamma-ray imagers have been improved [1][2][3][4] to realize sufficient angular resolution to locate the sources as well as sufficient energy resolution to reject background.…”

a b s t r a c tGamma-ray imagers with the potential for visualizing the distribution of radioactive materials are required in the fields of astrophysics, medicine, nuclear applications, and homeland security. Based on the technology of the Si/CdTe Compton camera, we have manufactured the first commercial Compton camera for practical use. Through field tests in Fukushima, we demonstrated that the camera is capable of hot spot detection and the evaluation of radioactive decontamination.

“…In some cases assessments have been made directly in real conditions in a power reactor (TUSHT of Sonar device in Phenix reactor), as long as it was possible. In other cases, they are performed in experimental or research reactors in France (OSIRIS), Belgium (BR1, BR2), Norway (HBWR), USA (ATR), for example [25,82,144,146,147,[150][151][152][153][154][155]. Some convenient experimental adaptations may be necessary to perform remote electric and acoustic measurements via mechanical bounding to a delay line, and to control the experimental conditions (irradiation, temperature), within volume limitations.…”

Abstract. The ANIMMA conferences offer a unique opportunity to discover research carried out in all fields of nuclear measurements and instrumentation with applications extending from fundamental physics to fission and fusion reactors, medical imaging, environmental protection and homeland security. After four successful editions of the Conference, it was decided to prepare a review based to a large extent but not exclusively on the papers presented during the first four editions of the conference. This review is organized according to the measurement methodologies: neutronic, photonic, thermal, acoustic and optical measurements, as well as medical imaging and specific challenges linked to data acquisition and electronic hardening. The paper describes the main challenges justifying research in these different areas, and summarizes the recent progress reported. It offers researchers and engineers a way to quickly and efficiently access knowledge in highly specialized areas.

“…Gamma imaging is another technique of great interest in several fields such as homeland security or decommissioning of nuclear facilities in order to localize hot spots of radioactivity (Gmar et al, 2011). A γ-camera to address this issue called GAMPIX has been developed by CEA LIST in France 10 based on the Medipix2 chip hybridized to a 1 mm thick CdTe substrate.…”
