Resumen
Since 1983, the Sealed Source Production Laboratory at the Nuclear and Energy Research Institute has been
providing products and services to the private and governmental Brazilian users of industrial radiography and
nucleonic control systems. Radioactive sealed sources are commonly used in nondestructive tests as
radiography to make inspections and verify the internal structure and integrity of materials and in nucleonic
gauges to control level, density, viscosity, etc. in on-line industrial processes. One of the most important
activities carried out by this laboratory is related to the inspection of source projectors devices used in industrial
radiography and its constituent parts as well as remote handle control assembly drive cable and guide tube
systems. The laboratory also provide for the users iridium-192, cobalt-60 and selenium-75 sealed sources and
performs quality control tests replacing spent or contaminated radiative sources. All discard of radioactive
source is treated as radioactive waste. Additionally, administrative and commercial processes and protocols for
exportation and transport of radioactive material are developed by specialized departments. In this work are
presented the mean processes and procedures used by the Sealed Source Production Laboratory such as the
arrival of the radioactive material to the laboratory and the source projectors, mechanical inspections, source
loading, source leaking tests, etc.
