제2차세계대전 전후에 시작된 식품조사에 관한 연구-개발 노력은 이미 결실단계에 들어서, 여러나라에서 다수 품목이 실용화 단계에 접어들었다. 우리나라에서도 최근에 식품조사에 관한 이용성과 실용화에 대한 관심이 높아지고 있지만, 방사선 조사를 식품에 적용하기 위해서 해결되지 않으면 안되는 문제가 산더미처럼 쌓여있는 것이 현실이다. 전리방사선에 의해서 처리된 식품의 안전성과 잇점에 대해서는 많이 보고되고 있다. 식품 방사선 조사에 대한 최근의 흐름을 보면 방사선 조사량이 증가되고, 대상 품목도 점점 확대되고 있어서 상대적으로 안정성에 대하여 새롭게 검토하여야 할 측면이 많아지고 있다고 할 수 있다. 국제연합식료농업기구(FAO), 세계보건기구(WHO), 국제원자력기관(IAEA)가 합동으로 설립한 국제식품조사고문그룹(ICGFI)은, 1990년 이후 식품조사기술의 안전성과 적절한 이용에 대하여 더 많은 정보를 제공하고 있다. 여기에서는 ICGFI가 1993년에 발행한 책자를 기초로 하여, 세계 여러나라의 연구-개발상황과 실용화 수준, 식품조사 이용의 주요한 문제점을 설명하고자 한다. 또한, 우리나라 수의분야에서의 현황에 대하여 간단히 생각하여 보고자 한다.

The purpose of this study was to examine the consumers' acceptance of irradiated foods according to sociodemographic characteristics and the factors to distinguish subjects with differential levels of their willingness to buy them. Data were collected from the 365 women living in Youngnam area by the self-administered questionnaire. The results from this study were as follows. First, consumers were concerned regarding food safety issues in general and particularly preservatives. Second, many subjects had not heard of the irradiated foods and showed wait-and-see attitude in the willingness to accept them. Consumers' willingness to purchase them were higher than any other cases if radiation would not remain in foods. Third, the results from the discriminant analyses showed that the concern toward food safety, perceived innovativeness, willingness to pay more for organic foods, and knowledge of irradiation were the factors to distinguish groups with differential levels of willingness to purchase the irradiated foods. The results from the study imply that accurate and scientific information about food irradiation should be given to the consumers.

Korea Institute of Radiological and Medical Sciences has provided various beam irradiation services to researchers using a 50 MeV cyclotron beam line. In particular, since the neutron beam service uses the nuclear reaction between protons and beryllium, the possibility of activation of the irradiated sample increases by using a high current. In this study, MCNP 6.2 and FISPACT-II 4.0 were used to evaluate the possible activation during the 35 MeV 20 ㎂ neutron beam service, which is preferred by the researchers. As a result of the calculation, if the iron, copper, and tungsten samples were irradiated for more than 1 hour, long-lived radioisotopes were produced and their radioactivity exceeded the standard level for self-disposal. Under the conditions of 2 hours of daily irradiation, no activation occurred in the building materials, and the internal exposure of workers due to air activation inside the irradiation room was very insignificant. And when this air was discharged to environment, the radioactivity including this air was also satisfied the emission standard.

The Korea Institute of Radiological and Medical Sciences plans to produce ²²⁵Ac, a therapeutic radio-pharmaceutical for precision oncology, such as prostate cancer. Radon, a radioactive gas, is generated by radium, the target material for producing ²²⁵Ac. The radon concentration is expected to be about 2000 Bq·m^-3. High-concentration radon-generating facilities must meet radioactive isotope emission standards by lowering the radon concentration. However, most existing studies concerning radon removal using activated carbon filters measured radon levels at concentrations lower than 1000 Bq·m^-3. This study measured ²²²Rn removal of coconut-based activated carbon filter under a high radon concentration of about 2000 Bq·m^-3. The ²²²Rn removal efficiency of activated carbon impregnated with triethylenediamine was also measured. As a result, the ²²²Rn removal amount of the activated carbon filter showed sufficient removal efficiency in a ²²²Rn concentration environment of about 2000 Bq·m^-3. In addition, despite an expectation of low radon reduction efficiency of Triethylenediamine-impregnated activated carbon, it was difficult to confirm a significant difference in the results. Therefore, it is considered that activated carbon can be used as a radioisotope exhaust filter regardless of whether or not Triethylenediamine is impregnated. The results of this study are expected to be used as primary data when building an air purification system for radiation safety management in facilities with radon concentrations of about 2000 Bq·m^-3.

Medical electrical equipment - Part 1: General requirement for basic safety and essential performance of MFDS was revised as 3th edition and Medical electrical equipment Part 2-54: Particular requirements for the basic safety and essential performance of X-ray equipment will be expected to be announced as notification. Therefore this technical report was written to introduce provision of the particular requirements, replacement, addition, amendment. The purpose of this particular requirements is to secure requirements for basic safety and essential performance of X-ray equipment for radiography and radioscopy. X-ray high voltage generator, mechanical protective device, protection against radiation is included in this particular requirements. Medical electrical equipment - Part 1, Part 1-2, Part 1-3 is applied to this particular requirements. If the requirements is announced as notification, It is expected to widen understanding for basic safety and essential performance of X-ray equipment for radiography and radioscopy and play a part to internationalize of medical equipments.
