The development of dose evaluation program for personnel radiation dosimetry

The MOST issued a Ministerial Ordinance about the technical criteria on personnel dosimeter processors on August 1992. The final goal of this project to acquire the NVLAP certification of the NIST, and to transfer the acquired technology to the domestic nuclear industry. In this year the improved dose algorithm and the related S/W and H/W technologies were developed. A performance test of TLDs has been performed in beta and neutron fields included in remaining test categories under the ANSI N13.11. Development of ECFs and dosimeter screening procedures was done. The advanced dose algorithm has developed in this study. As a result of performance test, it was verified that the accuracy and reliability of the algorithm were improved. The developed program to implement the algorithm and the ECFs was substituted to the existing module in Teledyne 9150 system. For the establishment of standard neutron field, a calibration bench was designed and the fluence to dose equivalent conversion factors for Cf-252 source was evaluated. (Author)
