Purpose: Chemical dosimeters have a potential of evaluating exposure dose close to biological effects as their chemical reaction process with radiation. We have studied 3-dimensional spatial dose distribution and real-time evaluation. We aim to exposure dose estimation and quality assurance of boron neutron capture therapy. In this study we report on the possibility of biological effects estimation and real-time evaluation. Methods: We prepared PVA-GTA(GDL) based LCV micelle gel dosimeter. In addition, we developed optical CT devices for real-time evaluation. Then, we tested gel dosimeter and optical CT device with therapeutic X-ray equipment. Another case, we tested the neutron characteristics of EBT4 films for spatial distribution in neutron field. Conclusion: We have developed new dosimeter and device for real-time spatial distribution.
