☢ Geiger Counters DO Detect Uranium, Plutonium, Gamma, Alpha, and Beta Radiation.

ever thought about learning to use meters to make big bucks? around 6 figures just for measuring rad 72 hours per week? ojt.

Just noticed a noteworthy nuance here... Geiger counters in fact do not detect Pu or even Cs137, they detect emissions *from* isotopes -- ie, they just detect radiation -- not the isotopes emitting them. Scintillators detect isotopes.

This point is worth making because of some who claim their Gegier counters are detecting a range of specific isotopes, erroneously elevating Geiger counters to the status of scintillators.

@GoddardsJournal Ok, you got me there. You see the light, not the light bulb. =)

A GM ONLY detects radiation. A scintillator can detect and measure energy.

So, you are 100% correct. A scintillator can determine an isotope whilst a GM cannot. You, an educated person, can infer (possibly correctly) the isotope with a GM, but it is merely an educated guess based on circustances. If your green glass plate ticks... it's likely uranium.

This is probably the source of the error : watch?v=-c-bUv-uE_Q#t=2m54s

Not surprisingly Jones even tries to spin the error into his conspiracy matrix.

What the the guy was talking about were gamma scouts, witch only detect x-ray and y-ray, but those are not gieger counters. but yes you are right

[antiprotons]

@ubuntupokemoninc I am not sure what he was talking about. The current Gamma Scout is a Geiger Counter, having a GM tube and thin window for alpha. It reads alpha, beta, gamma, and x. I heard that the old version did not read all of this, so maybe that is what he meant? GM tubes have always measured high energy beta as well as gamma. Some cannot detect alpha and weak beta only because they cannot penetrate the tube casing.

@antiprotons

I have two cdv-715 and they are not even considered gieger counters, there was a guy on yt who was warning people about the model. But my cdv-700 can oly pick up beta gamma and x-ray, I wish it could pick up alpha, apparently there is a modification to the prop so it can pick up alpha, but it is quite expensive

@antiprotons

btw i subbed to you, i found your video very informative :)

[antiprotons]

@ubuntupokemoninc Thanks! The CDv715 is an ion chamber design, very similar in principle to a Geiger tube, which uses a bottom mounted plate ion chamber. They really are very similar. For something to be considered a Geiger tube, it needs to have a tube filled with a halogen gas and an anode and cathode allowing a circuit to complete when the gas is ionized. They can detect most any ionizing radiation, but only if it can enter the chaber and strike an atom. Cheers

@ubuntupokemoninc  Thanks!!!

Do some geiger counters have a wand that can be submersed in liquid to test radioactivity? I'm sure there must be...and it's probably pretty expensive.

[antiprotons]

@Wivanunu Yes, some can. I just bought an Inspector EXP, which has a long external probe with a very sensitive "Pancake" GM tube on the end. I could wrap that in plastic to submerge, but there is a risk if the probe is accidentally exposed to liquid and the plastic may block alpha particles.
