The problem is that the 451P falls short, at the high end, by two (2)
orders of magnitude of where he wants to be (500 R/h).  But, in what
aspects of performance did you find the 9DP deficient?

I might recommend the Fluke 451P. Although the Ludlum 9DP seems
promising, field testing proved unacceptable for what I needed in an
ion chamber.
