<\/div>I<\/span>CRP Committee 2 works on aspects of radiation protection related to the dosimetry of internal and external radiation for workers, members of the public and patients. The Committee 2 is made up of 16 members from 10 countries (including Spain) and currently has John Harrison (Oxford Brookes University and PHE, United Kingdom) as Chair of Committee 2.<\/p>\n

The main dose quantities for radiation protection are the absorbed dose (in grays<\/em>), the equivalent dose and the effective dose (both in sieverts<\/em>). The concept of effective dose was developed by ICRP as a dosimetry quantity focused on the risk against the stochastic effects of ionizing radiation, mainly cancer, allowing the comparison of the estimated doses with official dose limits.<\/p>\n

The objectives set by the ICRP Committee 2 are the development of dose coefficients for the evaluation of occupational, accidental and medical exposures, the development and updating of biokinetic and dosimetry models and to provide reference dosimetry data for workers and members of the public. The group is currently working on the implementation of the 2007 radiation protection recommendations, according to ICRP publication 103, and on the development of a new generation of computer phantoms.The organization of work in Committee 2 is carried out based on 8 TG (\u201cTask-Group\u201d) thematic groups, whose maximum points of interest are currently:<\/p>\n

    \n
  1. the new dose coefficients for dosimetry for internal occupational exposure (series of OIR publications \u201cOccupational Intakes of Radionuclides\u201d) that will replace all the dosimetry material in publications ICRP 78\/68 (ICRP 60), and includes radon dosimetry<\/li>\n
  2. the development of age-dependent voxel-type phantoms that has allowed the generation of external exposure dose coefficients for members of the public in contaminated environments (soils, air) of eminent publication, and which will allow the development of age-dependent internal exposure dose coefficients for the exposed population,<\/li>\n
  3. the new generation of computer Mesh type phantoms and<\/li>\n
  4. dosimetry for non-human biota.<\/li>\n<\/ol>\n
