The European ALARA Network

This survey was carried out from October 2006 to January 2007 via the
EAN
Forum. The aim was to determine if and how the operator of a nuclear
installations takes into acount, in the dose planning for a job, the
occupational radiological incidents and mishaps. The questionnaire
contained the following
questions:

• If this is taken into account, does a specific methodology exist?
• Have
  you examples of scenario (biological shielding defaults, ventilation
  defaults, unplanned dose rate, fire, etc.), which have been used for
  these kinds of prevision?
• Is that planning required by the authority?
• Is there a dose criteria, above which an incident has to be reported to the authority?

Answers from 6 different countries have been received.

This survey was carried out from
September to November 2006 via the EAN Forum. The aim was to establish
the state of the regulations concerning the management of radioactively
contaminated soils due to activities related to facilities from the
nuclear fuel cycle (i.e. nuclear power plant, research reactors, fuel
cycle facilities, excluding uranium mines and mining sites). The
questionnaire contained the following questions:

• What is the regulatory framework within your country regarding the management of radioactively contaminated soils?
• Are
  there any release criteria (in terms of individual or collective dose,
  Bq/g…) for unrestricted and/or restricted use of such a site?
• What are these criteria and how are they used?
• Do you have any example of such a contaminated site which was finally released from regulatory control after remediation?

The European ALARA Network has
considered that it would be useful to make a specific survey in order
to evaluate the dissemination of the justification, limitation and
optimisation principles rhough Europe. A questionnaire was prepared by
the EAN Newsletter Editorial Board and sent to all EAN (18 countries)
and RECAN (22 countries) national contact persons.

Such
a survey was first undertaken in 2001 and its results were published in
the ALARA Newsletter issue N°9. However, at that time, it was mainly
limited to EAN member countries. Since then, the enlargement of the EU
has led to several new implementations of the European Directives 96/29
and 97/43 that are directly inspired by ICRP N°60 Recommandations
[1990]. In addition, some non-member states are using the IAEA Basic
Safety Standards for Radiation Protection [1996] that are also based on
the Recommendations made by ICRP in 1990.
