Contribution to the radioanalytical determination of heavy metals in the working environment of welders

Description

Heavy metals can be the most important toxic substances in welding environments. Their chemical behaviour is related to welding aerosols; hence, reliable analysis of these aerosols is quite important. Activation analysis by fast neutrons /14 MeV/, and radionuclidic X-ray fluorescence analysis /241-Am source/ were used to determine selected metals /Fe, Mn, Cr, Ni, Mo/ in aerosols produced during welding of high-alloy steels with MIG technology. Sampling was done by filtration using micro-pore filters. A multichannel analyzer /MCA S80 CANBERRA/ and Si/Li, Ge/Li detectors were used to process the analytical signals. Appropriate statistical parameters were calculated. (authors)
