The main conference topics are focused on current problems in Radiation Protectioa Thanks to the great effort of ICRP, IAEA and other international organizations, the basic principles of radiation protection are set and probably would not be changed in the near future. Though the fact, that these basic principles are adopted, the priorities have to be set with regarding the primary aims of radiation protection, with applying the appropriate standards of protection and safety at the national levels. Here is great effort to attain the standards of the more developed countries. It is known, that all measures taken against any hazard depends on the financial resources which should cover the protective measures. In addition to other political and social values, the radiation protection must correspond to widely accepted ethical values of the people affected by these regulations. Ethical values relating to protection require that the total harm to human health should be minimized and substantial resources should be allocated to the protection of human health. In the Slovak regulations, the radiation protection philosophy and policies of Basic Safety Standards which are based on the three concepts of justification, optimization and limitation, as well as on the general requirements for practices and interventions, are reflected. What is still needed is the system of operational documents and decrees in the field of radiation protection. These documents should be in agreement with the legislation of the European Communities. Nevertheles the organization of the radiation protection shoud continue to be under the state control.. The today economic situation in our country does not allow to cover all protective measures. We hope at least in continuing process of the proper training and qualification of professionals, together with the possibility to be equipped with the appropriate devices and systems. For reviewing and assessing the effectiveness of the protective measures the quality assurance programmes should be included. The most important source of information on risk in human are comprised in epidemiological studies. In Slovakia some basic information, necessary for assessment of the health effects of various radiation sources on the population are already gained. With regard to the assessment of possible risk, it is necessary to continue this research work. It is challenge for us to connect these studies with highly appreciated Slovak cancer epidemology register, which is one of the best in Europe. 4 2ľRHDJasnápodChopkom The papers presented in the Proceedings are not edited, also the tables and figures are not changed.
