Nuclear facilities have a limited lifespan of around 30-40 years. The decommissioning process, which itself can take 40-60 years, involves:
During the decommissioning process, workers are at risk of exposure to airborne radioactive material. To manage exposure, workers routinely wear personal lapel air samplers. Fixed area air samplers are also used to monitor larger areas and to pinpoint possible sources of radioactive particulate matter.
