National reports on applied radiation risk assessment methods

The TENORM branches which are of any relevance for each participating countries were selected for dose assessments.

Germany: The highest occupational exposure occurs in oil and gas exploitation, i.e external exposure due to working at drilling platforms and at pipe storage sites. The highest dose due to inhalation of dust was found for removal of scales by sandblasting. Therefore this method is now prohibited and replaced by high pressure water jet method.

The highest exposure to members of the public result from stay at river banks contaminated by untreated discharge of pit water from hard coal mines.

Czech Republic: Within the titanium pigment industry the highest occupational exposure result from pre-processing of limonite ore via inhalation of dust. The improvement of work conditions lead to a significant decrease of exposure. The local population is not affected by this industry.

Hungary and Slovenia: The dose to members of the public resulting from coal combustion is lower than 0.3mSv/yr

Romania: The dose to members of the public in case of staying at red sludge dumps was calculated. The highest dose results from inhalation of radon and progenies. Nevertheless, the exposure is overestimated due to the use of Rn 222 concentrations measured 10 cm above ground.

Belgium: The external exposure resulting from phosphogypsum stockpiles was calculated for "likely" and "unlikely" assumptions.

Poland: The dose to miners in underground hard coal mines were calculated. While for the "nominal" scenario (1,800h/yr) the external dose dominates for the "real" scenario the radon inhalation gives the highest contribution to the total dose.
