Training course on radiological safety for using low activity sources

The objective of this training course is to satisfy the requirements of basic and specific knowledge demanded by the Argentinean Nuclear Regulatory Authority (ARN) to apply for individual licenses for Applications of Low Activity Sealed Sources.

To whom it is addressed

Engineers and technicians who want to get an individual license for applications of low activity sealed sources.


Spanish, English or French.

Specific topics related with applications of low activity sealed sources in each particular company. Smoke detectors. Drugs and explosive detectors. Material analyzers. Gas chromatographs.  


Basic regulations for radiological protection. Regulations for the safe transport of radioactive materials. Packages. Labelling. Limits for surface contamination. Decayed sources. Institutional and individual responsibility. Applying for licenses.


The duration of the course is twenty four hours. The course can be provided at the date and location that is convenient for each company (in Argentina or abroad). Each participant will be given an interactive CD with comprehensive technical information.


The course is given by specialists widely experienced in industrial applications of radioisotopes who make part of NOLDOR staff and are IAEA(*) experts for assessment missions in many countries.

(*) IAEA stands for International Atomic Energy Agency.
