Thorium welding rod exposure

[Marlin]

What is the annual whole body dose to a welder who grinds his own thoriated welding rods? This shouldn't be to hard there are a couple of sources, but I'll post in a week if no one gets it.

"The grinding of the rod to form a pointed end can take anywhere from 20 to 60 seconds depending on the skill of the grinder. For welders that grind their own rods, this can take a minute or even longer. Individuals who specialize in this activity can complete the task much quicker.  At a large facility, e.g., with 50 welders, a grinder might handle as many as 150 rods per day (ca. 3 per day per welder).  For the purpose of the calculations, NUREF-1717 assumed that the particle size AMAD was 1 um.

An individual welder sharpening his own rods was estimated to receive 20 mrem per year.  This would be reduced by a factor of ten or so if a local exhaust system was used.

A dedicated grinder sharpening rods for 200 hours per year without the benefit of a local exhaust system was estimated to receive approximately 800 mrem."
