Progress of Cryogenics and Isotopes Separation


The National Conference with international participation on New Cryogenic and Isotope Technologies for Energy and Environment - EnergEn 2018 is organized by the National Research-Development Institute for Cryogenic and Isotopic Technologies - ICSI Rm. Valcea with the scientific participation of the University of Pitesti and the University of Craiova and will be held at Baile Govora, in 2018.

In order to ensure good living standards, all risk factors are considered in ensuring work and life conditions. The urban lives we live can be influenced by the quality of air both at work and at home.

Amongst environmental factors, air is essential to a good quality of life. A component that demands close supervision is the radioactive gas Radon. It originates both from natural radioactive constituents of Earth’s crust and construction materials. This introduces variety to the places where Radon is found, both in terms of local geological structure as well as building characteristics. Radon concentration levels in inhabited buildings can also be influenced by the tenant’s daily habits. Both the presence and measures of reducing the concentration of this radioactive gas require its monitoring. The adoption of EU directive 2013/59/Euratom draw attention on protection of the population and working personnel at Radon exposure, in buildings with public access and workplaces, from any source of Radon infiltration, whether originating from the ground and/or from construction materials.

The Radioecology Laboratory INCDM “Grigore Antipa” – Constanta initiated a program of methodological testing and annual Radon monitoring. Preliminary results of Radon concentration measurements through an active method range from 10-429 Bq/m3 (Fig. 1). Constant supervision is maintained in order to consolidate observations of Rn concentration variation over time, as a function of meteorological parameters, this potentially serving as a benchmark for measurements in coastal areas.
