Abstract
Volume I of the UNSCEAR 2000 report consists of 5 scientific annexes dealing with radiation sources and levels of exposure.
annex A: Dose assessment methodologies (64 pages)
Annex B: Exposures from natural radiation scources (74 pages)
Annex C: Exposures to the public fom man-made sources of radiation (136 pages)
Annex D: Medical radiation exposures (204 pages)
Annex E: Occupational radiation exposures (157 pages)
The report to the General Assembly of the United Nations and the scientific annexes are available from the UNSCEAR website: http://www.unscear.org/reports.htm The annexes contain the expected wealth of data and evaluations. For each annex, there is only time to discuss one or two striking results.
The use of more realistic values for the atmospheric dispersion model results in lower estimates of the population exposure around nuclear installations and uranium mill tailings.
The worldwide annual average population exposure to natural sources remains at 2.4 mSv. The population exposure in Belgium is calculated using the UNSCEAR methodologies.
The radon dose coefficient is maintained at 9 nSv per Bq h m-3 (in terms of radon decay products), which is 50% higher than the value given in the new Belgian regulation that is based on ICRP 65.
The most comprehensive assessment yet is made of the worldwide exposures to fallout from atmospheric nuclear tests.
The average level of radiation exposure due to the medical applications in developed countries is equivalent to 50% of the global average level of natural exposure. The widespread use of CT in Belgium results in even higher values.
The collective occupational exposure to natural sources, significantly above background levels, is higher than to man-made sources.
