Again this topic ??? Ci to Bq

["Jean-Francois, Stephane" <stephane_jeanfrancois@merck.com>]

Are we still on conversion question or the never ending story of what is
heavier, 1 Kg or 2.204 Lbs ? Or what volume should we use, Liter, US Gallon,
UK Gallon etc. ?

The initial posting was a search for a software . OK it is not Monte-Carlo
simulation software nor thyroid dose evaluation software but a question was
asked to this group and I am proud of the people who simply answered the
question .

Are we all aware that the professionnal that some of us are should give the
example of tolerance especially in this scientific area of expertise ? Are
we all aware that the WEB is open TO ANYONE, from any contry and any age ?

With some previous postings, I do understand now why we will still continue
to judge a person by their pigmentation ,language, culture...or scientific
background !

Please continue to ask ANY question regarding Radiation Safety, I beleive
this forum is exactly for that, even if the problem can be solved with an
Excel spreadsheet.

Of course, my humble opinion on what I consider a non-radsafe topic ! (Sorry
if I'm out of line I told myself if I see another post on that topic in
September, I would reply...)

I would bet that the majority of U.S. HPs are weak in one or more of the
traditional<=>S.I unit conversions, due to non-use.  Quick, what's the 
SI equivalent of 1 mR/hr????  Are you sure?  Did you have to look it up?

Granted, the Ci/Bq conversion is one of the more likely to be learned
through
necessity, but obviously this isn't a universal experience.  

It is helpful to have the key conversions memorized, however.  The way I
first learned to remember the Ci/Bq conversion was to simply remember the
Ci is 2.22E12 d/m and the Bq is 1 d/s.  Dividing 2.22E12 by 60 s/m gives
the number of d/s (Bq) in a curie:  3.7E10.

P.S.: Please don't waste bandwidth with announcements that you DIDN'T have
to look it up! :)
