Thank you guys for this topic! I find it very helpful as I am still getting familiar with the new lingo. And it saves my time now because I don't have to google every acronym I come across on this site! ;D

NDA - Non-Destructive Analysis

HPSI --- shouldn't this be High Pressure Safety Injection instead of "Low"?

-HPSI --- shouldn't this be High Pressure Safety Injection instead of "Low"?
I would agree with that,
HPSI/LPSI pronunced hipsee and lipsee are terms I recall from working at BWR's for high or low pressure safety injection. I have also seen HPCI/LPCI which is the same thing but refers to core injection directly. HPI/LPI are basically the same systems but are system designations from B&W PWR plants.
maybe helps a little

Posing a question here .... Another RP and I disagree on the acronym uR/hr as it pertains to the Ludlum Model-19. Is it micro REM or micro Roentgen?

Yes, it's gamma one REM is one Roentgen.

....that factor is one for gamma, well .93 for roentgen but radcon math applies.

Rem
The Model 19 is a highly sensitive gamma µR/meter employing an internally housed, 2.5 x 2.5 cm (1.0 x 1.0 in.) NaI detector. The measuring range is 0 to 50 µSv/h (0 to 5000 µR/hr).
https://ludlums.com/products/health-physics/product/model-19
sievert is used for radiation dose quantities such as equivalent dose and effective dose
rem is an older, CGS unit of equivalent dose, effective dose, and committed dose
the rem has been defined since 1976 as equal to 0.01 sievert
-
OBTW,.....

Marlin probably hasn't even thought about the definition of REM since before 1966,....

Rem
Typically REM is REM and Rad is R but in this case I suspect that it represents both, so as an androgynous designation how sexist of you. [devious]

sew, from awl the high faluting technical expousements delivered here, we can conclude that the ludlum designers where sew cheep that they decided too save printing ink buy using r instead of rem.

Phone call to Ludlum HQ in USA and asked them. Their HP tech rep said the R stood for Roentgen. Case closed.

Dang this could have gone on for a lot longer. Who was that tech rep a salesman? Maybe he has a bias for historical nomenclature. I want a recount there may have been a hanging chad.

Silly question, if it is Roentgen why don't you have to convert to Rad or REM? The difference is small but still there.

Equivalent scales all you do is change the meter face. ;)

So, does this mean that MOST of us meter swingers have been reporting our results wrongly? The last site I worked at only had uRem/hr as a choice on the drop-down menu on VSDS.

quick look at faces show a scale difference witch will work with the math difference.

MicroR (Model 19) are used for finding radioactive material (Roentgen), usually outside RCA's (very sensitive, over response)
MicroREM (Bicron) are used for setting dose rates (Roentgen Equivalent Man)
Believe me, from experience, when they NRC sees that you have been using a MicroR for ISFSI and Protected Area boundary dose rates.....for many years, they will not be happy.

both meters (bicron and ludlum) use NaI (I recall once upon a time Bicron [not thermo fisher] advertised the detectors as organic),....
bicrons can be "doped" for low energy sensitivity or "undoped" for standard sensitivity,...
either instrument when "normalized" to a Cs-137 field will improperly respond in oh, I don't know, something like an Am-241 field (actually I do know),...
so, sieverts and rem are the same result on different scales, energy deposited, damage done, soft tissue,...
roentgens are not the same, roentgens are energy deposited into thin air, air don't get hurt, air don't get sick, air don't die,...
the detectors inside the little black or tan box and the electronics inside the little black or tan box don't care what symbols are painted or printed on the meter face,...
it's how you set your meters up,...
"R" is just an "R",....
it's just a symbol on a meter face, etc.,...
it can mean just about anything you want it to, IF you know what you want it to mean, and you know how to set it up to mean that,....
if all of the above leaves you in that "the world is flat and a rock is a rock" place,...
well then, you're not qualified to know what you don't know,...
BUT, you do know how to observe a needle on a meter face or note a digital figure on a display screen,....
and write down a number on a piece of paper or type an entry onto a computer screen,...
and that obviously has some value, since you're all getting paychecks to do just that,...
now,.....
case closed,.....
I'm bored,...

OMG!!! once again I forgot to accommodate the SCWE sensitive snowflakes with the emoticon translator devices,....

Cold case file reopened 8)
I doubt it Roentgen is a historical term as well as a more precise term for calibration. NIST does not want any association of Roentgen with Sieverts. Historical terms in RadCon are not that unusual, Thoron and Radon are a good example both are radon but the top of the decay chain, are uranium and thorium but Thoron to describe the gas at the end of the decay chain is not used that much any more.

I have to admit to trolling a bit but it sure helped kept this thread alive for a bit. ;D [GH]
