A have a calibrated Model 12-4-7 placed equidistant (and equal angle to my cylindrical systems) between to fusors to compare NPR. This arrangement is allowing me to compare performance of various modifications.

I would like a second check of my method for converting the dose read out to NPR. The detector is 82 cm from the centers of my fusors (and 15 degrees off-axis, the two devices and detect form a triangle). If the indicated dose is 32 uSv/h (3.2 mRem/h ?), then the NPR is 2.1E+6 n/sec. I used the gammaspectacular.com calculator and set # to 32, #/mRem to 10, cm to 82, and s to 3600.

Thanks.
