Technique of the organization and conducting radiating monitoring in the woods

TECHNIQUE OF THE ORGANIZATION AND CONDUCTING RADIATING MONITORING IN THE WOODS establishes requirements to the organization of radiating monitoring, selection, preparation for measurements of activity of caesium-137 in objects of the monitoring, the analysis and registration of the results of measurements.

RADIATING MONITORING IN THE WOODS (RMW) is conducted for the purpose of detailed studying of radiating conditions in the woods, accumulation of the data for working out of short-term and long-term forecasts of pollution of woods and wood production.

 

Objects of the radiating monitoring in the woods Wood laying with live cover on the soil; the soil PLANTS And THEIR PARTS: wood,bark, branches, needles (leaves) of trees of the basic circle; branches, needles (leaves) of growing trees; underbrush branches; plants of the live cover on the soil; herbs or their parts; mushrooms
 Controlled radio nuclide   Caesium-137
 Controlled parameters  Capacity of a dose of gamma radiation (СD);
Activity of caesium-137 in objects of RMW

Workers of laboratories of radiating control conduct:
measurements of CD, sampling of objects of RMW, the first processing and preparation of tests, delivering of tests and results of measurements of CD to the Establishment "Bellesrad".
