Analysis of Radon Concentrations in a Radioactive Working Space

Radioactive working spaces represent a true challenge for building service engineers in designing a ventilation and air conditioning system because these have to satisfy much more demands in comparison with normal systems.The authors have presented a specific case of ventilation and air conditioning in a space were radioactive wastes are managed and radioactive pollution can occur. The paper presents the components of the system and their functioning mode. For testing the functionality of the ventilation and air conditioning systems in a radioactive waste management plant is mandatory to identify the radioactive pollution sources. Taking into consideration that future activities of the radioactive waste management plant don’t foresee activities which generate considerable levels of radioactivity, testing of the ventilation system was carried out by monitoring the potential gas emissions from a mixed cement-liquid effluent treatment process which is the most common procedure in a radiological building. After the analysis of the experimental data recorded during the several days it can be concluded that the existing system satisfies the demands of radon parameters.
