International recognition, experience, promptness, professionalism, scientific expertise, affordability are our guidance.

Our competitive advantage is that we are unique on the Romanian market and partly in Eastern Europe (except for the Czech Republic) in terms of the type, profile and quality of services provided by the LiRaCC Laboratory, in the context of the prospect of market demand in the coming years.

The productive and innovative fields of activity that we offer to the public, which also include research and development activities, have a high added value.

We are in the TOP 5 radon Laboratories in Europe that have the complete palette of services from screening to mitigation and post mitigation measurements. We are unique in Romania by measuring radon in all anthropogenic relevant environmental factors: Soil, Water and Air.

We aim to promote the highest standards of excellence and ethical principles in all our actions to measure, control and reduce the risk of exposure to radon and other carcinogens with an impact on public health, in conjunction with the principles of sustainable development and the guidelines of Directive 2013/59 / EURATOM.

Our Research

We design solutions aimed to monitoring, control and reduce radon concentration and implicitly to remediate and prevent the health risks of exposed people.

The aim is to evaluate the quality of indoor air by determining the radon concentration, to make a complete diagnosis in order to identify the source of radon and to design a cost-effective remediation solution, with minimal architectural impact on the construction.

Our Partners

We are very grateful for our partenerships with both public and private sectors: hospitals, clinics and medical offices in Romania, educational buildings (nurseries, kindergartens, schools, high schools, universities), private companies Kronospan, Philips Romania and others, NATO military bases in Romania, Bulgaria and Italy, and local public institutions in the counties of Arad, Cluj, Timiş, Sibiu, Suceava, Bihor, Alba, Buzău, Bucharest, Iaşi, Maramureş, Mureş, etc.

Between 2019 – 2021, in partnership with Cluj-Napoca City Hall, we developed a research in Cluj-Napoca area, and also in Floresti in partnership with Floresti City Hall. The objective was to assess the concentration of radon in schools, kindergartens and nurseries in the city, as well as in public buildings under the administration of town halls, according to the legislative obligation in force. At the same time, the PILOT project for the implementation of radon remediation solutions at the first school building in Romania was initiated as a national premiere and is underway in Cluj-Napoca, which will be taken over as an example of good practice by local administrations.
