Re: why wiki may be a poor source
I am very interested in the RATE team that is working these issues now.
Interesting. You are aware of some recent work by the RATE team?

Re: why wiki may be a poor source
Nonukes,
Not recent. Within last 10 years. Are you aware of any?
No. But you said you were "very interested in the RATE team that is working these issues now." I don't know of any such team, and I thought you were saying that you did know.
I had read that the Nation Center for Science Education(need to find link to verify) was going to create a team to verify the RATE team's research.
Where did you read that? As I understand it, there aren't any science issues to verify. I don't think there is any significant issue with the RATE team's science based calculations, and the team's conclusion that despite the scientific issues, that the impossible happened anyway seem quite outside of the realm of the science. Why would a secular organization even bother until the RATE team's work shows up in for peer review?
You know whether or not you read something. Why do you need a link to verify that?

Gorsh, I feel snubbed. And there are others.
If it helps a bit, I freely acknowledge that you know more about the subject than I do. It's not hard to find posts where you've corrected me.

Re: why wiki may be a poor source
It distinguishes our level of certainty and the type of evidence we have that causes us to come to a particular conclusion.
If we are rigid about that distinction, we won't be able to have discussions with creationists. Creationist insist that micro-evolution is evolution from wolves to dogs, however slow, and does occur, while macro-evolution is evolution of say a land animal-kind to a whaley-kind, and cannot occur cause you did not see it.

I enjoy hearing about new findings in the radiometric dating world. To discount the RATE findings just shows the ignorance of those that don't read their findings.
We have read them and we have discussed them here at length. This stuff is not new.

The point is there was interesting data that came from their work.
When are you going to get around to telling us what was so interesting? All of the quotes and links I've seen posted of the RATE study data have come from other people. You have posted diddly squat. What do you want to talk about?

Instead of saying, "they are wrong" can someone with UNDERSTAND and EXPERIENCE in this fields explain how their research was flawed
That's a very reasonable question. I think you want whoever provided you with the answer to your question to back it up with some evidence. So what did you think of the answer given at the link JonF posted in Message 81? I note that you never responded to JonF.
I highly recommend starting with the article at the link below.
http://www.asa3.org/ASA/education/origins/helium-rw.pdf
The short answer is that the analysis shows that the assumptions used in coming up with accelerated escape of helium are unfounded and refutable using evidence from the original paper. In addition ages obtained from the same zircons using U-Pb give ages inconsistent with the "leaky zircon" dating.
Now we can go back and forth about whose analysis is correct, but other evidence makes that kind of dickering unnecessary.
Independently from that, there is plenty of evidence that radioactive decay have actually been constant over a relevant time interval. Data form supernova SN1987a indicates that decay rates for radioactive nuclides are the same today as they were hundreds of thousand of years. We also have evidence that the decay energy of some high mass alpha emitters was constant over hundreds of millions of years which leads to the conclusion that the decay rates were also constant.
There has been lots of back and forth between scientists and the writers of the original study, and it might be worthwhile to try to form an opinion of who is the winner. But it turns out that there is lots of evidence that the earth, sun, and solar system are billions of years old. One debated study won't change that.

Re: On Geiger Counters
How can one be sure as to what atomic one is looking at?
When you use a geiger counter alone, you cannot be sure. That's why methods of that type are not used to do radiometric dating.
Something to consider. Each radioactive decay emits a particle of a characteristic type and energy. We can confirm the type of decay by measuring that energy and by looking for the daughter products produced by the decay. For example, Cobalt 60 decays by beta decay. Each decay emits gamma radiation of about 1.3 Mev and a low energy beta particle. The daughter product is a stable isotope of Nickle.
What is to say that noble gas in hard rock is not radioactive?
One method for analysis is as follows.
Instead of simply sticking a Geiger counter next to a bulk sample and learning absolutely nothing useful for determining the age of a sample, we instead use a mass spectrometer to determine the exact composition of isotopes in a sample. There is absolutely no question about what isotopes are being measured.
What you are attempting, namely looking for issues in radiometric dating by asking random questions that are unrelated to the processes and methods actually used is unlikely to result in stumbling upon anything of real interest. Might I suggest doing some research into what techniques are actually being used, and then repeating the attempt after having done that?

(I am not sure if it is even radiation or light.) It's the activity of the nucleus from which radiation is emitted.
Why don't you put together a post with three or more sentences in it and tell us exactly what your objection is? Between your tendency to express yourself in vague ways and your frequent departures from conventional science, I cannot even guess at what your point is. Maybe you've raised an important issue here, but what is it?

Re: Interested
Due to the fact that the magnetic field was significantly stronger in the past, and cosmic particles that cause background radiation are highly vulnerable to changes in magnetic field penetration, its highly likely the historical effect of this phenomenon is highly significant to long-life decay rates.
There is no evidence that any of these things affect decay rates. Every attempt to link a real world cause (e.g. neutrinos, cosmic radiation) to the supposed affect on decay rates has been an absolute failure.
The patent application in the EU failed because the scientists and their lawyers were utterly unable to correlate the measured decay rates with solar flares or neutrinos or even to describe how someone else might do so.
The supposed science you are relying isn't nearly as steady as it was the last time you were here, and it was shaky even then.

Re: Interested
So there is an existing and logical cause and effect that would by its very nature effect decay rates.
Lol!
Mindspawn, perhaps you have forgotten that you and I discussed this neutron proposal in depth and that by the time our discussion I had listed a number of consequences of your 'neutron delay' proposal for which you had no answers.
Here are some consequences you are neglecting.
1) The decay rates you need to show a less than even one billion year earth are of the same magnitude as the neutron flux you are requiring since one neutron prevents one decay.
2) The isotopes in a radioactive sample would become increasingly heavy over time. That is not observed. Again the rate at which this would happen would be related to the rate at which you are claiming things would decay if not for neutron particles.
3) Radioactive samples that are shielded from neutrons would then return to their extremely high decay rates. For example, we should expect that the uranium in a shutdown reactor to decay away rapidly due to the neutron shielding placed all around the reactor compartment. Yet such behavior is not observed.
4) Since you are claiming that the neutron flux is slowing current decay rates to reduced levels, the neutron flux must exist right now, and not at some time in the past. It is easy to show that such a flux would be lethal to all biological life.
The neutron principle does not work. What's more, I am pretty clear that a review of our past discussion will reveal that you know that it does not work.

Re: Interested
please explain your thinking here. I'm not following. I require nothing more than the existing neutron flux for this to work.
Wrong. As I explained to you before...
If a neutron prevents a decay, then the neutron must exist proportional to the number of decays prevented. In order to have enough neutrons to convert a million year decay rate into a billion year decay rate, you need enough neutrons to prevent 999/1000 decays.
The parent isotope would only become heavy if there was a net gain, not a net decay.
You are claiming that the decays are stopped by neutron absorption. Such a thing would convert a nucleus to a higher and heavier is isotope. There is so evidence of any such conversion. I am not even complaining about the gain weight rather than a loss. I'm talking about a change in the isotopic ratio. In the earlier debate you claimed that lighter isotopes would replace the heavier ones that after absorption, but there are limited light isotopes and your scenario cannot work.
3) Yes, if completely shielded from the neutron flux they would revert to their natural decay rate. However most neutron shields do not shield for high speed muons which create the neutron flux from within the sample.
You scenario is does not apply for a nuclear reactor which must shield against all radiation. Ple
In the case of a nuclear reactor high speed muons are easily stopped by lead shielding and steel shielding. Neutrons are stopped by boronated poly shielding. The U-235 ought to be consumed at high rates. We ought to detect within the reactor compartment after shutdown high levels of gammas produced by nuclear decay. Instead we find that the U-235 is not lost and there are no extra decay gammas. In the previous discussion, you relied on another poster to describe a similar situation before you punted on this nonsense.
Please show that the current neutron flux is lethal to life.
The current neutron flux is not lethal to life. However the neutron flux required to make this scheme work would be lethal. The amount of flux required to slow down the decay of 1 cubic centimeter sample of U-238 after I isolate it isotopically, so the neutron flu must exist everywhere on earth since you don't know where I am going to move my sample. And the total number of neutrons/sec must match the rapid decay that it is supposed to be preventing.
I should also mention that the neutron flux in a nuclear reactor is continually monitored because the neutron flux is proportional to reactor power. There aren't any significant number of muon induced neutrons in a nuclear submarines reactor. You are just talking garbage.

Re: Interested
Below is a link to the previous discussion on this exact same topic. I find that I was able to come up with a lot more objections to your scheme.
See Message 942.
If there is an effect, surely neutrons are not the cause.
By the way, this next quote is you acknowledging to PurpleYouko that a neutron flux does not affect decay rates.
From Message 954
PY writes:
First of all as I have pointed out above, the effects of neutron flux on decay rates has been tested rather thoroughly and categorically ruled out as a possible way to change decay rates.
Secondly and much more seriously, the kind of thermal or fast neutron flux needed for any isotope to capture a neutron would be many orders of magnitude higher than any form of organic life could survive. Such a flux on the surface of the planet would inevitably result in a sterile radioactive wasteland
