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 and dosimetric models; and reference data for workers and members of the public. The committee currently has 17 members and is chaired by Dr Hans-Georg Menzel. Membership list + photographs
For the 2007 Recommendations, Committee 2 was responsible for the preparation of Chapter 4 and Annex B, both entitled: Quantities used in Radiological Protection. Explanation is given of the calculation and intended application of the protection quantities, equivalent and effective dose.
Further information
Committee 2 is supported in its work by Task Groups, set up to work on specific issues:
Task Group on dose calculations (DOCAL) Further information
Chairman : Prof Wesley Bolch
DOCAL has the mandate to develop 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 Harrison
INDOS has the mandate to develop 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 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.
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 1 Task Group on stem cell radiobiology
Committee 3 Task Group on doses from radiopharmaceuticals
Committee 5 Task Group on radiation effectiveness factors for non-human biota.
|
Committee 2 also provides members of a Working Party of Committee 2, 3 and 4 preparing a report on the use of effective dose, including approaches in situations for which effective dose is not applicable
