the credibility is inconclusive or incomplete. At this level a facility would
declare an alert (see Appendix 6); and the facility or other potential target
would take action to improve security; an incident commander would be
appointed. In addition, other action would be taken to improve the ability
to promptly execute a co-ordinated response as outlined in Appendix 6 or
7 in order to prevent the act or to reduce any radiological, psychological or
economic impact.
There are indications that the threat is credible. At this level, a facility
would declare an alert and take other action consistent with Appendix 6.
For all threats, including those not involving a facility, actions would be
carried out to implement a co-ordinated national and local response to the
criminal activities and to reduce any radiological, psychological and
economic impact, as outlined in Appendix 6 or 7.
