5-06 FACILITY USE PROGRAM in Takasaki Advanced Radiation Research Institute Y. Fukuta, M. Hoto and D. Nogami Department of Advanced Radiation Technology, TARRI, JAEA 1. Introduction The facilities of JAEA are widely opened to users from universities, public institutes, and the industries, etc. Taking over the former system, FACILITY USE PROGRAM started in 2006, which is the system of facility use for the user’s purpose on fee-charging basis. There are 3 open use facilities in Takasaki; Co-60 Gamma-ray Irradiation Facilities, Electron Accelerator and TIARA (Takasaki Ion Accelerators for Advanced Radiation Application). In addition to them, some of the off-line devices can be used. We round up the Research Proposals every half year. And the special committee examines carefully the availability and the validity of the experimental plan. The facility usage fee has revised from this fiscal year. The details of the fee are the admission fee, the irradiation fee, the expendables fee and the additional charge. In case of Non-proprietary research, the users must report the irradiation result to JAEA, which exempts them from the irradiation fee. JAEA opens the reports to the public. Universities can also apply through the facility use program of the University of Tokyo. Such applications are accepted as priority case. Table 1 shows the outline of the program. Table 1 Classification of FACILITY USE PROGRAM. Purpose Research and development Classification Result General Non- proprietary Referee Yes No Priority case Proprietary Except R&D Commercial Charge* A B C *A = the admission fee + the expendables fee, B = the admission fee + the irradiation fee, C = the admission fee + the irradiation fee + depreciation. 2. Use in FY2009 There were 18 Research Proposals in FY2009 at Takasaki Institute, and 17 of them applied to Non-proprietary use. Including the users from priority case, we accepted 230 applications from 59 users. Table 2 shows that the percentage of the users from universities exceeds the others except for Co-60 Facilities. Figure 1 shows classification of all 230 applications. On TIARA, Non-proprietary use occupies more than 50%, while less than few percents for the other facilities.

Public Relations The information like an outline of this system, guidelines for applicants, format download etc. can be seen on JAEA website as follows: http://sangaku.jaea.go.jp/3-facility/ 01-intro/index-02.html. In addition to this, we have the “Project for Promotion of Shared Use of High Technology Research Institute”, which is one of the subsidiary project of Ministry of Education, Culture, Sports, Science and Technology (MEXT). This project intends that commercial users promote shared use of facilities, which develops the whole activity of science technology from Basic Research to Innovation Creation. An outline of this project can be seen on website as follows: http://www.taka.jaea.go.jp/innovation/index.html.
5-07 Radiation Control in TIARA Safety Section Department of Administrative Services, TARRI, JAEA 1 Individual monitoring (1) Individual monitoring for the radiation workers Table 1 shows a distribution of effective dose of the radiation workers in FY 2009. The effective dose values of almost all radiation workers were below the detection limit (0.1 mSv). The maximum dose was 0.6 mSv/y due to the overhaul of the TIARA AVF cyclotron. Table 1 Distributions of the effective dose of the radiation workers in FY 2009.

Small amount of 41 Ar, 11 C and 13 N were detected for some time during operation of the cyclotron or experiment, but the pulverized substances ( 65 Zn, etc.) were not detected.
