Delivering reliable results is the objective of laboratories in charge of radioactivity measurement in the environment. To be sure of their results, these laboratories use "standards" (sample of radioactive material for reference) and participate in exercise to test their expertise and their methods.
In this video, you will discover step-by-step the process used by IRSN for producing a standard, before learning its different application, either as a reference for devices that measure radioactivity or as a test sample for laboratories participating in advanced measurement exercise called "interlaboratory comparison".
