In 1970 – 1980 this knowledge was completed by the planning, development, built and operation of complex detector systems during 3 high-energy experiments at the European Organization for Nuclear Research CERN.. The knowledge about the measurement and surveillance of radioactivity goes back to 1965.
1980 – 1989 Dr. Ulf Fischer worked as executive post in the industry. By planning, development and construction of new detectors and measurement systems, Dr. Ulf Fischer hast developed and introduced new and improved procedures.
Dr. Ulf Fischer is author of many scientific papers on radiation measurement systems, detector properties und surveillance of radioactivity in the atmosphere and ground level air.
Dr. Ulf Fischer is a member of the German “Fachverband für Strahlenschutz” and active in the environmental working group.
PTI was established in August 1989. Since 1990 PTI cooperate in the field of surveillance of radioactivity with” Centralne Laboratorium Ochrony Radiologicznej” (CLOR) at Warsaw.
