First	  announcement	  	  ICRP	  Symposium	  on	  Radiological	  Protection	  Dosimetry	  Historical	  Review	  and	  Current	  Activities	  	  The	  University	  of	  Tokyo	  Thursday,	  February	  18,	  2016	  	  Organized	  by	  the	  International	  Commission	  on	  Radiological	  Protection	  (ICRP)	  	  with	  support	  from	  Nippon	  Foundation	  	  	  Background	  	  lCRP	   Committee	   2	   is	   responsible	   for	   the	   development	   of	   dose	   coefficients	  for	   the	   assessment	   of	   internal	   and	   external	   radiation	   exposures;	  development	  of	  reference	  biokinetic	  and	  dosimetric	  models,	  and	  reference	  data	   for	   workers	   and	   members	   of	   the	   public.	   The	   Committee	   and	   its	   Task	  Groups	  are	  currently	  engaged	  in	  a	  large	  program	  of	  work	  to	  provide	  revised	  dose	  coefficients	  that	  implement	  the	  2007	  Recommendations	  and	  introduce	  improvements	  in	  methodology.	  	  ICRP	   Committee	   2	   works	   closely	   with	   the	   International	   Commission	   on	  Radiation	   Units	   and	   Measurements	   (ICRU).	   It	   also	   works	   with	   the	   other	  ICRP	  Committees,	  for	  example	  in	  current	  work	  to	  provide	  advice	  on	  the	  use	  of	  effective	  dose	  as	  a	  protection	  quantity.	  	  	  	  	  Objectives	  of	  the	  symposium	  	  ICRP	  Committee	  2	  welcomes	  this	  opportunity	  to	  discuss	  the	  current	  work	  with	  Japanese	  scientists	  and	  practitioners,	  covering	  topics	  including:	  Ø Scientific	  bases	  of	  ICRP	  dose	  calculations	  Ø Current	  status	  of	  the	  development	  of	  models	  and	  data	  Ø Application	  of	  the	  models	  and	  data	  to	  dose	  assessments	  for	  workers	  and	  the	  public	  with	  focus	  on	  environmental	  exposures	  after	  accidental	  releases,	  risk	  assessment	  and	  radiation	  monitoring	  Ø Use	  of	  Equivalent	  and	  Effective	  Dose	  as	  protection	  quantities	  Ø Research	  needs	  and	  future	  developments	  ICRP	  Symposium	  on	  Radiological	  Protection	  Dosimetry
