I.S.C.Lab List of Products and Services

We would like to introduce a case where a "Becquerel counter for food" was manufactured as a radiation detector for food inspection. Due to the accident at the Fukushima Daiichi Nuclear Power Plant, radioactive substances were found in a wide range of food products. In response to this situation, monitoring was conducted in accordance with the "Manual for Measuring Radioactivity in Food during Emergencies" for general food items. In light of this trend, as the demand for measuring radioactive cesium concentration in food increased, our product was equipped with a Becquerel counter that combines CsI(Tl) scintillator and MPPC. By 2024, a total of 27 units of this product have been delivered. 【Features of the Becquerel Counter for Food】 ■ Improved measurement accuracy through optimization of the CsI crystal shape ■ Flexible response to customer needs and proposals for suitable technical designs ■ Capability for small-lot production of various types *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case of manufacturing a "CsI(Tl) radiation detector for treated water" as a residual radiation detection device for the Fukushima Daiichi Nuclear Power Plant's treated water. Following the purification of contaminated water resulting from the Fukushima Daiichi Nuclear Power Plant accident, there is a high demand for precise inspections to ensure that the large amounts of treated water stored in tanks are harmless to the environment and human health before being released into the ocean. It has become urgent to evaluate whether the residual radiation levels after secondary treatment meet the regulatory standards for treated water and the standards of countries that allow ocean release. Development and manufacturing began in 2021, and a total of five units have been delivered by 2024. **Features of the CsI(Tl) Radiation Detector for Treated Water:** - Proven reliability and assurance in the field of environmental radiation measurement - Flexible response to customer needs and provision of suitable technology - Capability for small-lot production of various types - Strengthened immediate delivery system for special specifications and proven track record - Support for consistent manufacturing from CsI(Tl) crystals to signal measuring instruments *For more details, please download the PDF or feel free to contact us.*

We would like to introduce a case of manufacturing a "NaI(Tl) radiation detector for treated water" as a residual radiation detection device for the Fukushima Daiichi Nuclear Power Plant's treated water. The contaminated water, such as water used to cool fuel debris, contains radioactive materials, and the treated water that has been purified using multi-nuclide removal systems (ALPS) still contains tritium and other radioactive substances. It has become urgent to evaluate whether the residual radiation levels after subsequent secondary treatment meet the regulatory standards for treated water and the standards of countries that allow ocean release. We began developing and manufacturing this product in 2018 and have delivered a total of eight units by 2024. **Features of the NaI(Tl) Radiation Detector for Treated Water:** - A proven track record of trust and reliability in the field of environmental radiation measurement - Flexible response to customer needs and provision of suitable technology - Capability for small-lot production of various types - Strengthened immediate delivery system for special specifications and proven results - Support for consistent manufacturing from NaI(Tl) crystals to signal measuring instruments *For more details, please download the PDF or feel free to contact us.*

At Kobe University of Commerce, research is underway to develop measurement techniques that utilize the direction of radiation to remove background noise and improve measurement sensitivity. We would like to introduce a case in which we received a request in 2023 for the development of a high-precision scintillator to be used in these measurements. Preliminary research conducted at the university required special structures, including double-sided light readout and full mirror finishing. To meet these requirements, we conducted structural design and prototype testing, identifying suitable conditions for crystallization, processing, and sealing. We established high-quality manufacturing and processing know-how to respond to these special requirements and delivered the finished product in July 2024. [Implemented Design and Processing Technologies] ■ Full mirror finish ■ Double-sided readout ■ Selection of reflective materials *For more details, please download the PDF or feel free to contact us.

We would like to introduce our "ultra-pure NaI(Tl) scintillator," developed in collaboration with Tokushima University for the purpose of dark matter exploration. We began research on purification using ion exchange resin methods in 2012, and by 2014, we successfully developed ultra-high purity NaI(Tl) crystals at a world-class level. Since 2019, we have started research on a hybrid method that combines recrystallization and ion exchange resin methods, achieving K-free levels below 20 ppb. 【Features of the Ultra-Pure NaI(Tl) Scintillator】 ■ Participated in the PICOLON project from 2011, accumulating crystal manufacturing know-how ■ Achieved world-class ultra-purification with radioactive impurities such as U and Th at the level of 10 µBq/kg ■ Contributed to cutting-edge research in astrophysics (numerous papers published using this detector) *For more details, please download the PDF or feel free to contact us.

• Radiation detector

Our company develops and manufactures NaI crystals and CsI crystals, which are key components of radiation detectors. In particular, CsI crystals are used in applications such as environmental radiation measurement in nuclear power plant decommissioning and rivers, as well as radiation measuring devices in food. Additionally, the technology for ultra-high purity and large-scale NaI crystals that we develop enables applications such as detectors for cosmic dark matter, which have been difficult to detect until now. 【Business Overview (Partial)】 ■ Development of sodium iodide and cesium iodide crystals, which are alkali halide-based crystals for radiation detectors, as well as the development of new combinations of alkali halide crystals. ■ Research and development of a hybrid Bridgman crystal manufacturing method that combines the Bridgman method and the VGF method. *For more details, please download the PDF or feel free to contact us.
