基本説明
This publication reviews what is known about the effects of radiation upon such biotic types (or of similar organisms, where more precise data are lacking) with regard to the effects of mortality, morbidity, reduced reproductive success, and chromosomal damage. Drawing on this information, the report derives a set of derived consideration reference levels for each biotic type in order to help optimise the level of effort that might be expended on its environmental protection, or that of similar types of organisms, and thus serve as points of reference in any wider consideration of what authorities may wish to do under different exposure situations.
The various factors that should be taken into account when considering what to do if the derived consideration reference levels are likely to be attained are also discussed. Some broader background information on the types of animals and plants used is also given. Additional information is provided on advice with regard to extrapolating
and interpolating the limited set of dosimetric models to other shapes and sizes of animals and plants.
The Commission acknowledges that, in many circumstances, exposure to radiation is but one factor to consider. It therefore intends to provide high-level guidance and advice upon which regulators and operators may draw in order to demonstrate compliance, where necessary, with the wide range of international and national environmental legislation that already exists, or is likely to emerge in the near future.
It also intends to supplement this introductory report with additional relevant data sets, and with further guidance on issues such as radiation weighting factors.
