The very (radio)active life of Pierre C.C

In this short tale, we describe a year of Pierre Chris Curry's ionizing radiation (IR) exposure, assessing and summarizing how much he has been exposed to over a year of his fictive life, cumulating the different types of exposures (either due to natural radiation, occupational and medical exposure), while staying reasonably credible. We have limited ourselves to IR exposure. As a recognized specialist in interventional cardiac surgery, Pierre provides lectures at international conferences requiring overseas flights. When not traveling, Pierre lives in Brittany in an area where there is high natural background radiation, owing to significant concentrations of radon, a radioactive gas produced from the natural radioactive decay of uranium found in rocks, granite in this case.

Natural exposures correspond to half of Pierre's total yearly exposure. Therefore, where you live, and your life habits have an important impact on your radiation exposure levels. Medical exposures take the second place in the ranking, but these exposures are punctual. Although his professional exposure is the lowest percentage, this represents a chronic exposure which is continuous over the duration of his working life, and alongside the natural exposure, is building on over-time. Although Pierre calculated total yearly dose was 58.4 mSv, significantly higher than the average in countries such as France, UK or even USA, his excess risk of death from cancer was still very low 0.292%.
