The levels of exposure are consistantly below the P.E.L. with only a few test being marginal. The 2-3-4 machine test results (exp/pel) ranged from .10 to .78 at the core set stations, while at the core set station of the 4-5-6 machine, the results (exp/pel) ranged from .05 to .28. These improvements were dene at a considerable cost, in both time and money. If you need any further information, please feel free to ask.
