Post-Chernobyl monitoring and controls survey reports archive

Monday 21 September 2009

A continuous programme of assessing the need for restrictions has been undertaken. Special surveys, termed 'de-restriction surveys', or sometimes 'summer surveys', were performed at farms where there is confidence that restrictions are no longer needed.

During these surveys, the whole flock is monitored at the time of year (mainly July and early August) that gives maximum radiocaesium concentrations. Monitoring takes place within 24 hours of the sheep being brought down from the hills, to ensure levels of radiocaesium have not started to decline. If the whole flock is below the radiocaesium limit, the farm is considered for removal of restrictions.

The reports from the surveys can be found at the links below.
