Radioactive Device Licensing

A Canadian purchaser and a United States supplier were both unaware of the Canadian radioactive licensing requirements for certain ignition exciters found in gas turbines. Some of these ignition exciters contain radioactive materials such as Krypton-85. Many of these exciters have a radioactivity level that is exempt in the United States, because it is below the threshold of 1,110 kilo becquerels (30 micro curies). In Canada however, the threshold for Krypton-85 is lower at 10 kilo becquerels.
