“Ex-Polon” started its activity in 1992 as independent, private business entity. It was established by mgr inż. Krzysztof Kwieciński. Firstly, its scope of activity concerned repairs of radioactive contamination equipment. Until that time, all such actions were carried out by the service department of ZTJ Polon in Warszawa which was subsequently liquidated. Over the course of the years, the company has widened its activity, completing untypical, individual orders taking into consideration particular requirements of the customer who ordered the service. Since 2004 we have started to conduct trainings in radiological protection in medicine (courses for the position of Inspektor Ochrony Radiologicznej[1] and Ochrona Radiologiczna Pacjenta[2]). Our partners are subcontractors from the entire territory of Poland. “Ex-Polon” provides services for units which perform measurements of radioactive contamination, such as sanitary and epidemiological stations or particular military units. The company is represented by mgr inż. Wojciech Kwieciński, graduate of the Faculty of Automotive and Construction Machinery Engineering of Warsaw University of Technology.
