RESUMO
Some companies in Korea have sold beds which contain a processed product containing monazite powder. Consumers may receive external exposure by radiation emitted by progeny radionuclides in uranium and thorium, and internal exposure through the breathing of radon progeny radionuclides produced in the decay chain. Thus, in this study, age specific dose conversion factors (mSv y-1 Bq-1) by external exposure and dose conversion factors by internal exposure (mSv y-1 per Bq m-3) were derived. Besides, a dose assessment program were developed to calculate dose by taking into account real conditions. And the age specific dose was evaluated using the radioactive concentration measured by the NSSC. As a results, external exposure was assessed to get effective doses in the range of 0.00086 to 0.0015 mSv y-1 by external exposure and a committed effective doses in the range of 1.3 to 12.26 mSv y-1 by internal exposure for all age groups.

The nuclear emergency exercise programme (NEEP) is a PC-based application intended for design and planning emergency preparedness and response (EP&R) exercises for a potential nuclear emergency in Korea. The application programme allows EP&R staff to create and edit exercise scenarios based on information customised for a specific nuclear power plant's emergency plans. NEEP includes the following features: (1) step-by-step guide to developing new exercise scenario according to emergency alarm level and potential accident type, (2) database of specific plant's field exercise scenarios that can be easily modified by users, (3) generating master scenario events list and messages of exercise participants and (4) allowing the quantitative evaluation of exercise participants from the view of exercise objectives and evaluator guides. NEEP also features tools for queries, reports and visualisation that can be used to create documentation during the scenario planning and exercise evaluation processes.
