Took me a while of reading up on radiation dating techniques, but I found this little bit after like an hour of reading:

There is no way to do this, not even in theory.

If the metal is simply contaminated with radioactive dust, one could decontaminate it by washing it off (or sanding, or grinding as necessary).

If, however, the metal is radioactive because it was been irradiated by neutrons, there is absolutely no way to make it no longer radioactive except by waiting for it to decay into stable isotopes. In your example, neutron irradiation of iron will produce iron-55 and iron-59 with half-lives of 2.68 years and 44.51 days respectively. The general thumb rule is that it takes ten half-lives to decay sufficiently, so you'd have to wait almost 27 years. If, however, it was one of the many iron alloys that contain cobalt it will take closer to 53 years for it to decay since cobalt-60 has a half-life of 5.27 years.

Neutron radiation is quite rare (basically only in a nuclear reactor). If the iron rod were irradiatied with the much more common alpha, beta, or gamma radiation, it would not become radioactive at all.

If the iron is radioactive, even melting it would have no effect.

Note that iron does not activate very well. If there is no cobalt present, irradiated iron could only be mildly radioactive and present no large risk. Just because something is radioactive does not mean that it is automatically unfit for human contact. After all, you are radioactive and I assume you contact other humans.




Particularly the bit that even melting iron wouldn't change it's radioactivity. Would the process not be the same for AL?

I also read that the only real way to date Aluminum is to figure out the date that it would have fallen to earth from a meteorite. This piece wouldn't count, as it's already processed by something. The aluminum in it has already fallen to earth, it didn't begin it's life on earth.

Quote:

Aluminium-26 can be used to calculate the terrestrial age of meteorites. After the breakup of the meteorite parent body, it will be bombarded by cosmic rays, which will saturate it in aluminium-26. After falling to earth, 26Al production ceases, which means that the amount of 26Al in the sample can be used to calculate the date the meteorite fell to earth.




I don't completely understand dating techniques, but it seems like aluminum would not be reliably dated if it was man-made space debris. Only in the larger context of when it fell to earth since it's initial formation is it's dating even remotely reliable for anything.

UFO Metal Found And Its 250,000 Years Old!




claimed to be 250,000 years old and they're dating it because it was found next to
two bones from an unnamed animal that went extinct between 10,000 years ago and
80,000 years ago


how exactly did they come to the conclusion that it was 250,000 years old again?

250K years is a pretty damn longtime, if they didn't progress past soft metals like aluminum its possible most of the evidence that would be "dug up" has been destroyed.






Thats impossible. Archaeological evidence would be everywhere, theres a whole host of materials and waste that an advanced society would produce that would easily survive that long.




but there are artifacts from that long ago. hence this article.

and if abundance is an issue 250,000 is a fairly long time. there could have been (definitely have been) cataclysmic events that could have destroyed these artifacts

Unless life has been seeded here personally by some miraculous act of god, we can only draw one conclusion. The universe produces life, there fore it must exist elsewhere. To say otherwise is to suggest the physics here are some how different then the rest of the universe.

If the aluminum was dated, it would only prove that the aluminum was that old. Not that the object that the aluminum was in was that old.

Unless I'm misunderstanding what I read about it.

Im confused on the dating. It cant be carbon dating cause the material needs to be organic aka made with carbon backbone in the molecular structure. Alumimum is a pure element, and is not organic.


Confused on how its dated.

lol half our space programs involve attempts to find ETI in some way shape or form. The question of "are we alone" is something that would be common to any intelligent lifes ponderings and sending out probes en masse to catalog everything is something they would more then likely do. Its something we're already planning on doing, or at least dreaming of doing.

Geologists know their rocks but are worse than anyone when it comes to dates.

Here's an example of sedimentary rocks that were supposedly laid down over hundreds of thousands of years.

The problem is that there's a tree standing upright through it, which would have had to stand upright for that long of a time, defying common sense, if the geologists are right.

The way this strata was laid down was clearly rapidly in a large scale flood in which the sloshing water sorted the different layers by density very quickly quickly. Perhaps the great flood...

But my point is that any of these antediluvian (Atlantean) artifacts that come up are always mis-dated. Anything from before the great flood always gets dated as being a couple hundred thousand years old, I think the truth is probably closer to 10,000 years. And its not ETs either, its the advanced civilization that existed before the great cataclysm.

It would be dated by radioactive decay. So radio active aluminum decays into stable magnesium at a known rate and looking at the ratio between radioactive and stable can give you a date

So what if we have a program that is looking for life. That is meaninglessunless. It finds seething which it hasn't. The closest galaxy to.us is 3 million light years away. Life on this planet took a third of the lifespan of the universe to evolve into anything complex. It is unlikely aliens have came here especially in the distantpast. Could.d ed definitely  exist but probably didn'tmake it here
