Doses from Radiation exposure
Committee 2 is concerned with the development of dose
coefficients for the assessment of internal and external radiation exposure;
development of reference biokinetic models; and reference data for workers and
members of the public. The committee has 16 members and is chaired by Prof
Christian Streffer. Membership list + photographs
The committee is currently responsible for the preparation of a Foundation
Document on dosimetry that will be published with the new ICRP
recommendations, probably as an annex. There will also be a chapter for the
main recommendations that summarises the information provided in the foundation
document. The foundation document explains the dose quantities used by ICRP and
their application. The draft was presented for comments on the ICRP web site
for several months in 2005. After a further revision the draft will be
discussed by the Main Commission at a meeting on 22-24th March with the aim of
completion of the new recommendations within the year. Further information
Much of the work of Committee 2 is done by Task Groups, set up to work on
specific issues:
Task Group on dose calculations (DOCAL) Further information
Chairman : Prof Wesley Bolch (previously Dr Keith Eckerman)
DOCAL is responsible for the development of methods for the calculation of
doses from both external and internal sources of radiation.
Task Group on internal dosimetry (INDOS) Further information
Chairman : Dr John Stather
INDOS is responsible for the development of biokinetic models for radionuclides
entering the body by inhalation or ingestion and, working with DOCAL, prepares
reports on doses from radionuclide intake by workers and members of the public.
Task Group to develop a new human alimentary tract model Further
information
Chairman : Dr Henri Métivier
This Task Group developed a new biokinetic and dosimeteric model of the
alimentary tract. Work was completed during 2005 and the report will be issued
as Publication 100.
Task Group on radiation exposures of astronauts in space
Chairman : Prof Günther Dietze
This Task Group was set up in 2005 to assess exposures from the complex
radiation fields encountered in space, which include high energy particles with
unique high LET components, very different from radiation fields on earth. The
main discussion points will be: analysis and effects of the high LET
components; dose estimation systems / detectors; development of reference
doses; and application of the system of radiological protection.
Committee 2 also provides members for Task Groups of other committees:
| |
Committee 1 Task Group on epidemiology relating to exposures to alpha-emitting
radionuclides;
Committee 3 Task Group on doses from radiopharmaceuticals; and
Committee 5 work on dosimetry for non-human biota.
