Nonetheless, the background radiation ranges at sure areas of the world could also be greater than 0.1 μSv/h.
Measure the radiation ranges on the floor of the container through the use of the hand-held radiation monitor, with a preset alarm degree. The preset alarm degree must be 0.2 μSv/h above background radiation degree on the location of measurement. The measured radiation ranges mustn’t exceed the preset alarm degree.
In case any container is discovered displaying radiation ranges exceeding the preset alarm degree, it must be instantly subjected to identification of supply of radiation with an Isotope Identifier (a handheld RDE can establish the particular radionuclide emitting the radiation), in line with the notification.
