Nano-crystalline Received in revised form 16 September HAp is synthesized by wet chemical precipitation route and ion exchange process is employed to replace 2013 of Ca ion with Fe ions. Thick film Fe-HAp sensors, having variable Fe doping concentrations, are prepared Accepted 17 September 2013 7+ by using screen printing technique. The Fe-HAp thick films are irradiated using Ag ion (100 MeV) with Available online 25 September 2013 10 13
