AW: [ RadSafe ] Easy radiation quiz.

[Franz Schönhofer]

John,

Thank you very much for your message.

If I had written that, I would have been submitted at least to a kind of
"prewarming" for flaming. The last nonsense which this person wrote on
RADSAFE, asking about dpm of a pCi-source, changing his question afterwards
to a "test", which all RADSAFErs failed according to his mails, then
changing his question to "particles leaving the surface", bla, bla, bla. 

Then he tried to sell used equipment on RADSAFE, later he started a "survey"
on instruments used by RADSAFErs. ?????

BTW I remember that in my PhD thesis, which was partly on very quick
separation of radionuclides by electrophoresis I described a separation of
Cs-137 from Ba-137m. I was very proud to be able to show this separation by
autoradiography and to demonstrate the decay of Ba-137. This was more than
30 years ago.

Well, John, I do not know, how old you are, but however you are not cynical,
but you pose the right question. This person - a troll and selfdeclared
wannabe radiation protection scientist - should be ignored. 

Best regards,

Franz

OK, silly trick question, trying to get someone to say it's a gamma
emitter when it decays by electron capture with no gamma to Ba-137m,
which emits the 662 kev gamma.

What I'd really like to know is, what's going on here?  Is there now an
entrance exam for Radsafe?  Have you been appointed proctor for this?
Why do we need to be quizzed?  Maybe I've gotten cynical in my old age,
but I can't help but wonder what the goal of all this might be.

We didn't do too well with our last quiz. Here is an easier one. This
should be common knowledge, so don't look it up, just answer off the top
of your head.
No updates, no clarifications, here are the questions, deal with them as
they are.

Part 1:
What is the type of nuclear decay in Cs-137?

What is the type of radiation given off from Cs-137?

What is the predominant energy in keV of the radiation given off from
Cs-137?
 Choose from:

662

156.8 

1173

if none of the above, list it. 

Remember we are talking about the isotope Cs-137. 


Respond direct to GEOelectronics at netscape.com, not  to the list 

Humor me, Thanks

George Dowell
