A week or so ago, I conducted a little experiment to see if a hot sample of uraninite would alter the growth pattern of ....ahem.....a small patch of mold on a...
Haha! Thats a neat experiment. Perhaps the mold is resistant. Might have to do it longer. If you had a 10 uCi Cs-137 disk it might work for ya :) ... ...
Go with what Marshall stated. REM stands for Roentgen Equivalent Man. A Roentgen is a gamma or X-ray measurement only. If your counts where all gamma...
FWIW, I've bought several bags of Brazil nuts and have seen no count increase with my pancake probe. I even took my blueQ to the local grocery- no indications....
Any "thin window" geiger tube will give an accurate COUNT of alpha particles. The alphas lose some percentage of their energy in the window (and in the air)...
Be very careful, it has been know that Gamma radiation mutates mold into a giant black cheese-seeker mold-monster. Better put a padlock on you 'fridge just in...
Bill,a few posts back one of fellows I belive it was Tracy, did a test with Brazil nuts and found a increase of activity, but he ground the brazil nuts up like...

It's a work in progress. Paul has over 400 radioactive minerals listed on his CD. I'm sure he just hasn't had time to put it on the web site. I see there are...
The mR/hr vs. CPM ruckus is as old as the hills. CPM is a universal language common to all -pulse output- detectors. I prefer it. If I know the capabilities...
I'm glad you posted this message, Marshall! This is a good "for instance" in my defense of and the usefullness of the CPM scale! Armed with this information,...
I agree, I myself don;t have the time or inclinatio to try to keep all the variuos units straight. CPM, absorbers, and KNOW your probe. Geo ... detectors. I...
... You've obviously never been troubled with serious static cling or lint issues. Anti stat are also used in web roll industrial processes (process paper,...
Sure 'nuff, Geo... Hobbyists can get virtually all the info they may need (and then some) with a 700, the stock hotdog probe, and an add-on pancake probe. ...
Correct you are, Marshall. And I didn't even look at the one sitting on the bench less than six feet away from me. Gosh, it's printed in white on black right...

Well, You could throw in, RAD = Radiation Adsorbed Dose = 10 ERG,s Per Gram of Adsorbing Material, 1 ERG = 10.00E-7 Joule Roentgen = r = An Exposure to...
I see alot of responses to this post, good. I havent read them all yet, but I will respond anyhow. I am still VERY confused. This is what i picked up from a ...

Alright, agreed. I understand what you are saying. It is why i started this out saying it would vary depending on all that you listed below. Perhaps its not...
Hey Sethmiester! Don't knock my new (CHEAP) sealed alpha source! 36 bucks for a 500 microcurie source, cant beat that. Too bad it will all be gone in a few ...
Further note: I noticed something about the ability to ionize, particularly for gammas, mR/h ?? Ok, fine. Cannot alphas ionize too? And betas? Wouldnt there be...
