experimental advise needed
jack
large PMT and scintillator block and have ortec pulse processing
electronics. My original plan was to obtain a small sample of Sr 90
for calibration of my MCA and other equipment as it has a rather good
beta peak energy for calibration at I believe .5 Mev. However ,none of
the science supply places I called will sell to an individual,only
institutional accounts and I am doing this on my own. So my question
is twofold... Does any one have any other ideas on how I can obtain a
small calibration sample of Sr90 and if not does any one have any
other suggestion of how to calibrate my mca ,pm ect. ?
Any help would be appreciated. jk

Ebay, and beta is hard to do, as you have to keep the light out, try gamma.
Mark Martin
If you visit the physics department at a university, you may be able
to borrow a sample long enough to do the calibration. I've borrowed
radioactive samples in this way before.
-Mark Martin
Gregory L. Hansen
That would have been my suggestion. The scientists I've known would have
been eager to help with such a thing, if they could.
Jack, I would really like to know more about your project. I've always
admired amateurs that can do high quality work in their free time and on
their own nickel.

... ahahaha... So, Al, are you over your cold now and it allowed
you to come back?... or was your swift come-back prompted
because *** [1] "I've got better things to do with my resources. ...
Goodbye and - FOaD - Uncle Al" *** ... you discovered that
you had such meager resources that it forced you to come back
already nine (9) days after have left?... or did you do some
soul (on your case sole)-searching and had to admit to yourself
that ... even if all your idiots are gnawing painfully on/at your balls
you just can't get way from them... ahahaha.... they, the idiots, do
control you, Al, and perverse as you are you love it... HAHAHAHA...
Good to have you back, Al, ... ahahaha... ahahanson

Yo, Al! Bad scene: You seem to have issues & attitudes facing you:
a)... The plethora of your detractors ignored you across the spectrum...
They gave you the silent treatment....
b)... even your few ethnic aficionados and that small band of your
athletic supporters did not welcome you back....
This silence is deafening, Al... Bad scene, Al...

Yeah hanson, we noticed but are trying not to contribute to the "river
of shit" part of the WWWPS. LOL! So let's put in some physics here.
Check out the drawing for the photon at,
http://www-personal.umich.edu/~janhande/sizedmatter/standard_model.htm
and
http://www-personal.umich.edu/~janhande/sizedmatter/jpegs/photon_particles.jpg
Two wavelengths long and a 4pi twist as predicted by our QVC model. The
more solid-like part is most likely the probability cloud of where the
energy is. So "someone" is thinking like we are.

PS. Old Man is back also if you didn't notice. ;-) Let's hope they give
up this whiney-ass crap -- it's certainly not a perfect world. But I
suppose UseNet is designed for whiners of all types. ;-)

Like I said, I have nothing against, Al. Al was one of the great
funny-men here. If some posters do feel that he "contributed"
to science, ahahaha... well, then that speaks much more for
their own instead of for Al capabilities.... ahahaha...
I am glad to see that Old Man aka Jako Epke is back. Dudes
like Epke, Gregory Hansen and Sam Wormley are essential for
a decent balance in this NG. These types represent & literally do
teach the classical and conservative way of physics, which is (1)
good for the youngsters in high school and college, and (2) they
are cherished icons to and balsam for the souls of posters, the
tardies, who think that the evolution of physics had stopped with
GR & QM and hence do love to wallow in the domain of the "bright
light under the street lamp that was lit...by/as Einstein himself had
said.... endlessly discussing/quarreling over SR/GR whether Albert
was right or wrong... with the pro and con being split mostly along
Jew and Goyim lines.... ahahahaha...
And then, Fredi, your are of course very perceptive in observing
that there are "all types of whiners" here at this 24/7 crazy party.
It's just like in the real world... at engineering meetings... at political
rallies etc... like at any congregation of minds where opinion Exchange
is free and does not attack your wallet... ahahaha...
This is free entertainment dude... cheap and hilarious... a joy actually
especially when you have a cyber i-billionaire in the crowd who can't
spell nor "do the math"... ahaha... right next to the hordes of all those
physicists (turned programmers by economic necessity), yet all of
them convinced that they will be next year's Nobelists... ahahaha....
The dirty little secret in cyber i-physics is that a classical MO of:
"Tell people something they know already, and they will thank
you for it. Tell them something new, & they will hate you for it...."
does NOT apply here at all... it will bring you, no matter what you say,
just another batch of whiners, as you have observed so aptly...
So, I still say: "Let'em sing... All of'em... It's a beautiful choir!
... ahahaha... ahahhaha... ahahahanson

Go get the morons, hanson, round 'em up and corral them. See if
you can find which witch doesn't know v = dx/dt, then let's have a
witch burning party.

Well, you may refer here to such luminaries like the genocide
advocate Ersatz rabbi Bobby Kolker, or his disciple HeilWut
Wabnigger with his metric screw issues, or perhaps the gassy
Geschisse from Gisse and his arse cained bitch arcane Bob
Cain who is in constant Pain, and the Grand Fumbler Van der
Moortel who proudly refers to himself as "The third Kacksacker"
... ahahaha... But, Andro, there are hordes of covens with witches
like that around who do institutionally not know that v = dx/dt...
ahaha... and even more of them do know less about the
consequent derivatives of v, ..... so, why burn the upper layers
right at the integration limit where the line of sight x emerges?
Theses witches --> "vee"tches ---> "vee-"deniers are valuable
indicators to the more virulent depths as seen in
http://groups.google.com/group/sci.physics/msg/76e07e1fe1c6f9de
which duly explains that
"Momentum equals mass times velocity! .... v = (dx/dt)
Force equals mass times acceleration!....... a = (d2x/dt^2)
Yank equals mass times jerk! ....................... j = (d3x/dt^3)
Tug equals mass times snap!........................s = (d4x/dt^4)
Snatch equals mass times crackle! ............. c =( d5x/dt^5)
Shake equals mass times pop!!....................p = (d6x/dt^6)
>
Therefore Andro, I must object to your proposal to burn'em...
Strenuously.. yes, siree!... very much so, I do!...strenuously!..
See, there are men of the cloth!... But I am a man of the flesh...
and hence I am keenly on the outlook for the tug of the
snatch that snaps, crackles, shakes and pops... ahahaha....
So, I prefer to leave the jerks, the yankers and the veetches
on the sidelines... in cold storage... for emergency use...
Ya gotta be pragmatic!... Now, Andro, you keep on whupping
them but don't burn'em!.... promiss?... because any conversion
of them is rather diffcult as can be seen in
http://groups.google.com/group/alt.sports.hockey.nhl.det-redwings/msg/c2557a6e45180e1d

You would do it anyway!....ahahahaha.... Besides, a few here
