Effective dose in SMAW and FCAW welding processes using rutile consumables

Abstract: The shielded metal arc welding (SMAW) and flux cored arc welding (FCAW) processes use covered electrodes and flux cored wire as consumables. Among these consumables, ones containing rutile are the most widely used, and since they have a considerable natural radioactive content, they can be considered as NORM (naturally occurring radioactive material). To calculate the effective dose on workers during their use in a conservative situation, samples of slag and aerosols and particles emitted or deposited during w… Show more

“…To do this, we used a time correction based on Bateman equations, taking into account decay and ingrowth corrections during sampling time, measurement and the time lapse between them. This analytical method was developed for NORM industries dose assessment (Herranz et al, 2014). We assumed that the activity of short-lived Rn progeny, during early gamma-ray measurements in filters, was unsupported by Ra and Rn.…”

“…To make these time corrections, as the presence in the air of short-lived radon progeny depends also on the presence of radon in the air, Rn in air has been obtained by direct measurements. With these Rn and gamma spectrometry data and the use of a mathematical treatment developed by us and used for dose assessment in NORM industries (Herranz et al, 2014), the activity concentration of gamma emitters in sampled aerosols and particles was finally obtained.…”
