To correct the correction, yours should actually be written: 

one microCurie = 2.22 million DPM not DPS. OR= 37,000 DPS  -  (not 3700

Here is a quick response to your question,  


I found trying to figure out the conversions in the sample problems very
useful in my study for the CHP Exam.  The 51.1 is a good example of a
factor I dissected to gain better understanding of the calculation.  It
is a compilation of several conversions that gets the answer to rem.


You will need to use the conversion of rad to Mev/g, given on the Exam
Equations, Formulae, and Constants Sheet

You will need to put the time information given in common units, uCi =
2.22 E6 disintegrations/sec, effective removal rate is in inverse days"

one microCurie = 2.22 million DPM nor DPS. OR= 3700 DPS.
