Abstract
This paper is related to a study on safety management of cosmic radiation in the aviation area, and as a comprehensive study encompassing not only aviation crew but also aviation traffic users, presents issues on an exposure to the cosmic radiation which authors predict may be intensified in a time to come. Although the government of the Republic of Korea has recently activated regulations related to the cosmic radiation, the following improvement measures are further urged to be carried out not only as a regulatory improvement for pushing ahead with effectiveness but also as a supplementary tool. Firstly, a dose limit corresponding to the international standard needs to be applied. Since the dose limit imposed by the Korean government is improperly higher than the international dose limit of the cosmic radiation, the present dose limit needs to be re-established in a range of "not exceeding the international recommendation". Secondly, a new methodology is needed such that aviation companies observe a yearly effective dose limit of passengers. A fact that only aviation crew is specified but passengers are excluded in the related regulation is based on a recommendation presented by the International Commission on Radiological Protection (ICRP). According to the recommendation, Korean government excluded passengers in the "Cosmic Radiation Safety Requirements for Crew". Among the present aviation regulations, there exists a protection standard for protecting aviation traffic users. However, it presents a damage protection only for ticket-related issues. Since this regulatory weakness provides a cause of endangering national health, the authors believe that an improvement in the regulation is needed without sticking to the recommendation from the ICRP. To this end, new regulations are strongly demanded from aspects of not only legal but also regulatory areas. The dose limit in accordance with the international standard is established. However, at least a minute amount of cosmic radiation is continuously acting on all people of Korea. Since more and higher level of cosmic ration may exist in the aviation space, an improved method of representing the minute amount of cosmic radiation in figures. As a result, a desirable regulation may be established for protecting not only crew but also aviation traffic users from being exposed to the cosmic radiation via a legislation of the desirable regulation.
