Beta Dose at Nuc Power Plants

[Darryl Kaurin <dkaurin@eden.rutgers.edu>]

Dear Jay,

Regarding beta skin dose rate conversion factors,

While not applicable to gross contamination, McWilliams et al.
(1992) determined a nice rule of thumb for discrete hot
particles.  For an Eberline RO2 or RO2A, the dose rate to tissue
at a depth of 70 um averaged over 1 cm2 is 150 times the open
window response (ie: 1.50 Gy/R).  This was recently found to
agree well (within 20%) for other hot particles types with
different measurement techniques (Kaurin et al. 1996).
