Personal dosimetry enhancement for underground workplaces

Result description

In order to determine how the effective dose is calculated, it is necessary to divide these areas into distinct categories by the following measuring procedures: continual radon measurement (to capture the differences in EERC between working hours and night-time, and also between daily and seasonal radon concentration variations); regular measurements of radon and its daughters to estimate the equilibrium factor and the presence of 218Po; regular indoor air flow measurements to study the location of theradon supply and its transfer among individual areas of the cave; natural radioactive element content evaluation in subsoils and in water inside/outside, a study of the radon sources in the cave; aerosol particle-size spectrum measurements to determinethe free fraction; monitoring the behaviour of guides and workers to record the actual time spent in the cave, in relation to the continuously monitored levels of Rn concentration.

    Zlepšení osobní dozimetrie pro podzemní pracoviště

  • Czech description

    Vypracování metodiky stanovení efektivních dávek je nutné pro každý typ podzemním prostor zvlášť a bude se opírat o následující měření: kontinuální měření radonu (postihnutí variací radonu během pracovní doby, sezónních variací atd.); měření radonu a krátkodobých produktů přeměny pro stanovení faktoru nerovnováhy a zastoupení 218Po; měření proudění vzduchu pro studium zdrojů radonu a pohybu ?kapes? s vysokými koncentracemi; stanovení podílu volné a vázané frakce; monitorování délky pobytu pracovníků v jednotlivých částech podzemních prostor pro navázání dat z kontinuálních monitorů při výpočtu dávek jednotlivých osob. Předpokládaným vstupem k řešení problematiky je kritické posouzení dosavadních přístupů k hodnocení ozáření plic.
