Tom, At Columbia our CRDM's from our R-20 outage this spring were from 13 Rem/hr to 85 Rem/hr. We replaced 20 CRDM's with an average dose rate of 39 Rem/hr.

What are the radiation levels of a typical control rod spud end and how many days decay between removal from the reactor and the measurement? I am a PWR type and am working on a BWR decommissioning project.
