AW: [ RadSafe ] DPM from 27 pCi Tc-99

[Franz Schönhofer]

Dear George,

You bombard me every few hours with your mails. I am sorry, but I am not
only not able to follow your "arguments", but also otherwise your mailings
are difficult to understand. 

First of all, please note that I am not going to take orders from you
regarding that I "have" to answer your silly questions. I take orders
neither from you nor anybody else unless those persons would be legally
authorized to issue orders. 

Secondly you claim (after I engaged to this topic), that this was only
intended for a test - ROFL (Rolling on the floor of laughter.....). If you
want to conduct tests you have to announce that beforehand. 

Third: You claim that only one RADSAFER was able to answer that question
correctly. Do you really want the RADSAFE community to believe that all of
them are absolute idiots and don't have a clue on radiation because they are
"not able" to answer this question which requires a simple multiplication by
2.22? What about the statistics of your "test"?

Stop distributing such messages. I would urge Marcel not to monitor your
messages, but to keep an eye on them especially regarding the above third
point. 

You claimed that I have called you a liar, a fool, a fraud and a troll. I do
not know, who has sent e-mails with this content using my name. I never have
sent anything like that. What may come close is my remark that there might
be another troll on this list.  

Anybody on this list who knows George Dowell and could explain to me his
mails? 

Best regards,

Franz

Franz, you have become strangely quite since I've challenged you to answer 
this novice question. You have called me a liar, a fool, a fraud and a 
troll. I submit that it is you that are the pretender.

Wes,

I did not send an answer to this question, because I thought it must be a
hoax. I thought that somebody who tries to sell on RADSAFE a whole bunch of
used instruments, which he claims to have used himself should be able to
convert pCi to dpm (or dps aka Bq), and should know that this is
irrespectable of the "substrate" or whether it is electroplated or not.
Assuming that he may have wanted to know cpm (and not dpm) he should know,
that this depends on the type of instrument used, the energy sensitivity,
the area of the detector, the distance to the source etc. etc.

Earlier contributions of Geo>KOFF to RADSAFE made me shake my head, but
because of my experience with being flamed on RADSAFE when I previously
questioned someones qualifications I did not comment.

Is this another troll on the list?

Best regards,

Franz

George,
The answer is 27 x 2.22 = 60 DPM, exactly.  The rate of beta emission into
the air from the surface is another number, smaller than 60. The count rate
(CPM) of some instrument placed on the surface is even less.

What is the surface DPM of a 27 pCi Tc-99 electroplated disc source? The
substrate is stainless steel. (by calculation only please)
