One the new stage on nuclear medicine development there is a need to solve a number of tasks. The choice of radiation shield materials is an important task, because they to a large extend determine radiation safety in the process of operation and volumes of radioactive emissions in case of decommissioning. The stage of decommissioning is final in operation life of such installations. In the article the authors present an estimation of the producer of cyclotrons PETtrace 880 on radionuclides, which arise in the composition of concrete biological shield of cyclotron after decommissioning in Pet-centre of Russian Oncologic Scientific Center named after N.N. Blokhin. It was shown, that the data of the producer can lead to underestimating the volumes of radioactive waste. The tasks for further investigation on the problem are outlined. The authors defined the role of induced activity estimation on the stage of design and decommissioning of the cyclotrons for radiological safety. For designed objects the elemental composition of protecting constructions should be included in design documents. The choice of the composition should take in account the activation capacity of doping and tracing elements. The adequate estimation of induced activity should result in optimization of design and construction solutions. Such an approach will allow realizing the future stage of decomposition in more efficient and safe way by reducing radioactive waste and dose costs for staff and population.

Introduction. An approach to the development of the organizational-technological model of the life cycle of a medical facility building is presented. Buildings of medical organizations have a number of features in the design, construction and operation. The buildings of nuclear medicine are subject to particularly high requirements of radiation and fire safety. Materials and methods. To organize the design, construction and maintenance of medical buildings, it is advisable to create and develop an organizational and technological model of the medical building life cycle. Such model was created by the author in the form of a business processes sequence. Confirmation of the effectiveness of the model is carried out with the help of multi-criteria expert evaluation. Results. To solve this problem, it is proposed a number of changes in the order of the investment project carrying. A new element is the Preliminary justification of the requirements for the health facility. It should become a mandatory document when obtaining a town-planning plan of the ground area, which is in Russia a de facto permission to design. It is also proposed to prepare technical requirements of three levels. The first level requirements are used for pre-design stage procedures. The requirements of the second level are included in the medical and technical design assignment. The requirements of the third level are applied to the detailed design, as well as to the construction and maintenance of the facility. Requirements are included in the requirement system and must be checked at key stages of the project. At the preliminary project phase, it is also advisable to make a technical and economic calculation with the justification of the main technical solutions and technical and economic indicators. This document should also include a project management plan. New elements are included in organizational and technological models of different stages of the object life cycle. Conclusions. On the basis of the developed model, it is proposed to make adjustments to the normative guideline used in the construction management. For example, it is necessary to make mandatory documents of the pre-design stage. These works have to be paid by investor therefore the standard of design cost has to be increased.
