Novel techniques for radiation protection & dosimetry
Increasing number of applications in medicine & research
• high intensity radiation fields (neutron sources)• ultra-high intensity lasers• increasing use of high energy hadron therapy
Two approaches to dosimetry
• passive systems• miniaturised systems
NEUDOS11, NUC 4th November 2009
The Basics...
• quantities (dose & kerma, etc)• xsecs (10-8 eV > GeV)
• detection methods (TNC, (n,p) )• production (10-8 eV - > GeV)

Field testing personal dosimeters
SCK-CEN have used bubble detectors for neutron personal dosimetry for 10 years:
