A quarter of a century after the Chernobyl accident you'll also see how children born over a decade after the disaster are still suffering from the radioactive fallout and finally a look at the less dramatic scale radiations most of us are subjected to and why the French nuclear watchdog is sounding the alarm over x.rays in hospitals.
