The breakdown of the different sources of radioactive exposure in France. According to this repartition, the total dose is around 3.5 mSv : natural radiation making up 2 mSv and artificial radioactivity making up 1.5 mSv. The natural exposure is primarily due – 60% – to radon. The artificial exposure can be traced back to medical examinations and treatment, with industry and research only contributing 1%. It is important to remember that these values are all averages.
