BackgroundlCRP Committee 2 is engaged in the development of dose coefficients for the assessmentof internal and external radiation exposures; development of reference biokinetic anddosimetric models, and reference data for workers and members of the public. TheCommittee and its Task Groups are currently engaged in a large program of work toprovide revised dose coefficients that implement the 2007 Recommendations andintroduce improvements in methodology.
ICRP Committee 2 works closely with the International Commission on Radiation Unitsand Measurements (ICRU). It also works with the other ICRP Committees, for example incurrent 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 Japanesescientists and practitioners, covering topics including: Scientific bases of ICRP dose calculations
 Current status of the development of models and data Application of the models and data to dose assessments for workers and thepublic with focus on environmental exposures after accidental releases, risk
assessment and radiation monitoring Use of Equivalent and Effective Dose as protection quantities
 Research needs and future developments
