Purpose: This paper aims to explore approaches for obtaining KOLAS certification for masks developed as protective equipment for use during evacuation processes in the event of a radiation disaster involving residents within a radiation emergency planning zone. Method: Various reports, papers, and data from the KOLAS accreditation bodies' websites were examined for this study. Result: Although domestic radiation disaster preparedness measures have been established to enhance resident protection, the distribution of protective equipment is limited to thyroid protection drugs. Supplementary support items like masks are necessary to prepare for radiation disasters. Currently, there is no KOLAS-accredited certification body for radiation protection masks. Conclusion: For masks that have established performance certification criteria, a dual process is required for KOLAS certification. This involves obtaining an official test report as an industrial respirator mask, receiving certification, and then obtaining a general test report based on internal standards.

원자력 발전소에서 사용되어지는 케이블은 전원 및 제어신호를 안정하게 전달하는 역할을 하며, 비상상태 발생시에는 원자로를 안전하게 shut-down시키는 통로 역할을 하므로 매우 중요하다. 케이블 상태 감시시 절연 및 피복재료는 종류 및 배합내용이 다양하기 때문에 종래의 자료로부터 전선과 케이블의 열화 또는 수명을 추정하기가 극히 어려우며 방사선에 노출이 되는 케이블의 경우 노화현상의 진행이 빠르고 방사선 열화로 수명이 단축되므로 국내 실정을 감안한 독자적인 검증방법 도출, 규제기술 기반 구축 필요 및 규제의 합리화와 효율화 필요성이 대두되고 있다. 기존에 사용해온 케이블 진단 방법에는 절연 파괴 강도 측정을 통한 노화진단, 산화 방지능력 측정을 통한 노화진단, 자켓 및 절연체의 판단, 연신율에 의한 노화진단, 케이블 Indenter에 의한 노화진단, 온도 및 방사선 등의 특정상태에 대한 평가, 유사한 환경조건에 대한 주기적 검토 등이 있다. 기존의 국내외 케이블 상태 감시방법을 조사 연구하므로서 케이블 열화에 대비한 수명관리 규제 기술 및 상태감시 (Condition Monitoring : CM) 기술의 평가 기준을 결정 하고자 한다.

The development of radioprotector is being actively conducted in order to reduce the damage from over radiation exposure at radiation accident or radiation therapy. So this study was confirmed for radiation protective effects using the Cynanchi wilfordii Radix that has been known to be effective for antioxidant activity, anti-cancer, immune enhancing effects. The method of this study was administered orally Cynanchi wilfordii Radix ethanol extracts to Sprague Dawley Rat(SD Rat) for 14 days once a day, while measuring changed blood cell, spleen index, liver and uterus tissue along the change in time of 1, 4, 7 and 21 days after X-ray beam of 7 Gy irradiation. As the result of the experiment, the experimental group's rats which are administered with Cynanchi Wilfordii Radix ethanol extracts showed a rapid recovery in white blood cell count(p < 0.05) and spleen index(p < 0.05). In addition, condensation of nuclei, cytoplasmic swelling, and inflammatory cell infiltration in experimental group's liver cell was decreased more than in irradiation group's component. Further, experimental group's Uterine gland decreased the apoptosis more than irradiation group's components did. It is expected that Cynanchi Wilfordii Radix extracts will be useful as a new radioprotector. With above in mind, this paper may provide appropriate implications with the field of emergency management such as radiation accident.

For the emergency radiation monitoring using gamma spectrometry, we should sufficiently survey the background spectra as environmental samples with systematic nuclide identification method. In this study, we obtained the gamma ray energy spectrum using a HPGe gamma spectrometry system from an air sample. And we identified nuclide of the gamma ray energy peaks in the spectrum using two methods -1) Half life calculation and 2) survey for cascade coincidence summing peaks using nuclear data. As the results, we produced the nuclide identification results for the air sample.

The gross alpha analysis of nasal smear samples for the radiation emergency and the additional follow-up steps were established. Cotton swab sticks using in local hospitals for nasal smear in Korea were used for the verification. The measurement results of standard samples spiked with certified reference source were well agreed within ${\pm}20%$ compared with reference values. The clearance ratio of smear samples conducted with wet smear condition showed higher value. To eliminate the quenching effect of liquid scintillation samples, dry of smear samples should be followed up before counting samples. Based on the measurement results, medical decision levels and internal dose assessment were established for the victims in the beginning of radiation emergency.

A real-time dose assessment system(FADAS : Following Accident Dose Assessment System) has been developed for the real-time accident consequence assessment against a nuclear accident. Field tracer experiment near Younggwang nuclear power plant was performed to improve the accuracy of developed system and to parameterize the site-specific parameters into the FADAS. The mean values and turbulent components of wind profile obtained through field experiment have been reflected to FADAS with site-specific conditions. The simulated results of diffusion model agreed well with the measured data through tracer experiment. The developed system is being used as a basic module of emergency preparedness system in Korea. The diffusion model which can be reflected site-specific parameters will be improved through field experiments continuously.

In 2007, the International Commission on Radiological Protection (ICRP) published Recommendations of the International Commission on Radiological Protection. Accordingly IAEA safety standards committees have reviewed and revised the BSS. The process of the implementation of the ICRP 103 into Korean radiation protection regulations has been continued. Although the new recommendations retain the fundamental protection principles, the impact of the new ICRP recommendations will necessarily be greater than ever before. ICRP recommends the application of dose constraint in planned situations and reference level in existing & emergency situations for strengthening of the principle of optimization. Dose constraints and reference level play a criterion on the level of individual dose as prospective and source-related values. Therefore it is necessary to apply dose constraints and reference levels to all nuclear and RI&RG facilities in Rep. of Korea. Dose constraints and reference level of occupational exposure will be set-up by the stakeholder itself with the cooperation of regulatory body. In this study, the implementation method was discussed to apply the dose constraints and reference level as the procedure for the optimization, not the tool of the regulation.

Intervention levels for foodstuff restriction in a radiological emergency in Korea are suggested based on the justification and the optimization through the cost-benefit approach method from IAEA Safty Series 109 recommendation. Intervention levels are specified for three broad groups of radionuclides with similar values of committed effective dose per unit intake and specified for two broad categories of foodstuff grouped according to value per kg. It is also discussed on the applicability of revised intervention levels for foodstuff restriction.

Meteorological Data Acquisition System (MDAS) and Meteorolocical Information Processing System (MIPS) have been developed for the measurement of the meteorological parameters at the Korea Atomic Energy Research Institute site. MIPS represents the measured meteorological data graphically on a computer screen. MDAS and MIPS are interfaced with real-time radiological dose assessment system (FADAS), which has been developed to rapidly assess the radiological consequences and to support decision-making under radiological emergencies.
