Probably work on reading up on detection methods.(See upstream attached overview on basics)
Why don't you read up on it? No need to fake arrogance. I'm the one suggesting new ideas here...not a geiger-counter on a satellite: atmosphere opaque to low-energy gamma/x-rays; but transparent to near-visible photons, right?
So is it really impossible secret projects came up with a way to detect x-ray/gamma via photon emission of collision with atmospheric particles? Sparsity/AI/DSP to work the data... truly impossible?
I have, more or less off and on semi continuously since the 1980s. FWiW I've read and edited multiple versions of guidelines to terrestrial radiometrics from several countries and the international agencies (such as the one I linked above).
No need to fake arrogance.
Just a bald statement of rather dull facts I'm afraid.
Does not sound impossible to me. I get if you're unaware of it or sounds impossible to you, yeah? OK? No worries. This may be related:
Just to be clear .. are you suggesting that a coin sized Cs-137 mining instrumentation source with 667 kev gamma peak might be causing observable cherenkov radiation?
And that no one has noticed or thought to look since 1900 or the post WWII Cold War boom in domain study?
Well doesn’t mean you might not be missing something, or not relating it. Anyway, the blue light is just something related. You know what I’m suggesting, it’s very clear. Why do you have to pretend a weaker version than deal with that?
Anyway, you’ve clearly got skin in the game in this argument, Aussie. I wonder what your role is: an interested observer or an involved party?
It should be clear by now that I've measured and mapped radiation events of several kinds for 40 odd years.
It's clear that you're suggesting there might be some novel as yet unknown way to detect and location pinpoint a coin sized industrial Cs-137 source used in a mining radiation gauge from the distance of a low orbit (?) satellite.
I'm open to hearing how exactly this might be achieved, I'm sure the other person in this parallel discussion would also have an interest, as they stated they're working at a US national lab in precisely this area.
If you turn to that discussion they've addressed the measured and known way in which the gamma radiation falls off with distance .. although they didn't address how that also falls off with air column mass (air pressure, tempreture, water vapor level (humidity)) etc. and determined this is possible to detect in a one second window from 40 metre distance.
It also rather rules out using direct gamma detection of such a weak source from 25km through the full mass of the atmosphere so, again, it'd be nice to have a concrete indication from you of what it might useful to look for.
Concrete, mind, and not more of this handwavy Sir Kenelm Digby Powder of Sympathy [1] remote sensing magic.
Hand wavy huh? Isn't it always those who know the least who have to trump up their pittance with arrogant dismissals of other people's ideas? I think so. Anyway, why don't you try having some power of sympathy for this idea (I posted above): So is it really impossible secret projects came up with a way to detect x-ray/gamma via photon emission from collision with atmospheric particles? Sparsity/AI/DSP to work the data... truly impossible? Does not sound impossible to me. I get if you're unaware of it or sounds impossible to you, yeah? OK? No worries.
So I'm going now. I do not want to do this with you all day. So I hope your day gets better from here, bye! :)

That's an interesting notion.
