The adsorption behavior of fission products to various soils was studied using a multitracer. The multitracer was prepared
by neutron irradiation of 235U. Distribution coefficients of fission products were obtained for seventeen kinds of Japanese soils. It was found that zirconium,
niobium, and rare earth elements show high distribution coefficients for all soil samples, however, elements like alkali metals
show varied values.

The new control system of pneumatic transportation apparatuses for neutron irradiation in Kyoto University Reactor (KUR) has
been developed based on the TCP/IP network for the purpose of integrated management of the apparatus. The control system is
comprised of PLCs, control PCs, database and web servers. Archiving logs of detailed information about irradiation enables
the secure operation and management of the irradiation system. The information stored in the server can be referred by remote
PCs and mobile phones through the internet. Combining the present facility with measurement and radiation management systems
it can realize advanced INAA methods and secure managements of radioisotopes.
