or radiation emergency. OILs are defined as the values of environmental
measurements, in particular dose rate measurements, above which specific protective
actions should be carried out in emergency exposure situations. The derivation and the
application of OILs are discussed, and an overview of the presently adopted values is
provided, with emphasis on the situation in the Nordic countries. A new, probabilistic
approach to derive OILs is presented and the method is illustrated by calculating dose
rate OILs in a simplified setting. Contrary to the standard approach, the probabilistic
approach allows for optimization of OILs. It is argued, that optimized OILs may be
much larger than the presently adopted or suggested values. It is recommended, that
the probabilistic approach is further developed and employed in determining site
specific OILs and in optimizing environmental measuring strategies. | | Publication date: | 01 Dec 1997 | | ISBN: | ISBN: 87-7893-034-0 | | Number of downloads: | 5499 | | Download: |  EKO-3-3-97-TR-1.pdf |
