Table 1

Reference exposure levels for the population according to international organizations and countries, taking into account the phase of the accident for each country. Doses are expressed as an effective dose (E), all routes of exposure taken into account.

1

With application of the principles of optimization and justification (CSP, 2018a, 2018b, 2018c).

2

During the first year, with optimization to be implemented as soon as possible.

3

Denmark, Sweden, Norway, Finland, Iceland.

4

The UK’s management doctrine insists on optimizing exposure during the transition phase, without providing a baseline.

5

Canada relies on the recommendations of the ICRP, with no specific guide value.

6

The USA considers that the use of exposure reference levels does not adequately address considerations specific to the nature of the accident and its consequences (NCRP, 2014). The protection strategy is based solely on the guide values for protection actions (EPA, 2017).

7

Spain, in its legislation, does not indicate exposure reference levels, but only preventable dose levels for the implementation of protective measures.
