The impacts of element-specific parameters (e.g. distribution coefficients of surface soil, concentration factors of soil to agricultural products and transfer coefficients of fodder to animal products) in biosphere assessment of radioactive waste geological disposal was discussed especially for the important radionuclides, C-14, I-129, Cs-135, Np-237.

In JAEA Nuclear Fuel Cycle Engineering Laboratory(JAEA-NFCEL), MOX fuel fabrication facilities and spent fuel reprocessig facilities are operated during over several ten years for the purpose of establishing the nuclear fuel cycle technology. In these facilities, we have to need to pay attention to plutonium. We present the internal monitoring technique for plutonium in JAEA-NFCEL.

The physicochemical properties of radioactive aerosols are important factors to assess internal dose at high energy accelerator facilities. In Kyoto University Research Reactor Institute, a generation of radioactive aerosols in ADSR (Accelerator-Driven Subcritical Reactor) facilities was studied as part of the research project of ADSR. The generation of radioactive aerosols in high intensity irradiation fields of ADSR was simulated by irradiation of the target room air at LINAC. We measured the particle size of radioactive aerosols in the target room during the acceleration period. Natural radon aerosols in the target room grew to the larger size because of an attachment of radon daughters to non-radioactive aerosols. The particle size of the produced radioactive aerosols was also larger with time. This would mean that a formation mechanism of the radioactive aerosols produced at high energy accelerator facilities is the same as radon one.
