Traduction de «De-watering screen » (Anglais → Français) :

In replacement of gross alpha and gross beta activity screening discussed above, Member States may decide to use other reliable screening methods for radionuclides to indicate the presence of radioactivity in drinking water.

Member States which wish to make use of screening techniques that are based on measuring total alpha and total beta activity need to pay attention to possible metrological limits (e.g. failure to take into account low energy beta rays), to select correctly the guideline value below which water is considered compliant, in particular for total beta activity, and take account of the cumulated impact of beta and alpha activity.

Member States may use screening methods to identify water with a potentially excess TID that requires further analysis.

8 . The Commission shall, systematically using the database established under Regulation (EC) No 1907/2006 to screen for substances that are harmful to water organisms, accumulate or are persistent, examine technical and scientific progress, including the conclusions of risk assessments as referred to in points (a) and (b) of Article 16 (2) of Directive 2000/60/EC and propose at least every four years the revision of the environmental quality standards laid down in Part A of Annex I to this Directive.

Among other things, the package will provide funding for increased surveillance and tracking of marine traffic, screening of all passengers and crew on board large commercial vessels entering Canadian waters, and the installation of new detection equipment at ports to screen containers, and it will include provisions for establishing restricted areas to improve port security, requiring workers who enter those areas to undergo background checks and screenings.

The specific themes are: increased surveillance and tracking of marine traffic, including near real-time identification and tracking of vessels in Canadian waters; the screening of passengers and crew on board vessels; installing new detection equipment in ports to screen containers for radiation; enhancement of the RCMP's emergency response team and the establishment of permanent investigative positions at major ports; enhancing collaboration and coordination among government departments and agencies; developing and implementing new international requirements; and continued improvement of port security through enhanced coordinatio ...[+++]n and collaboration.
