- Good day, Professor Masarik! A problem on Carbon 14 and Cosmic radition?
- If you find it beneath your worth, it seems you have colleagues you can confide it to, but it might even interest you. Here it is:
A) In normal cosmic radition, medium radiation dose on places on Earth (increasing with height) from cosmic radition alone is, I have gathered, 0.39 milliSivert per year.
B) Also in normal cosmic radition, the speed of production of carbon 14 is such that in ten years, the descent of atmosphere's 100 pmc to a theoretic 99.879 pmc is compensated, since carbon level stays roughly the same.
Now, there is obviously a connection between the levels, since carbon 14 is produced mainly by cosmic radiation hitting N14 high in the atmosphere (or so I have gathered).
But the problem is whether the connection is like a straight line graph (1:1, 2:2, 3:3, 4:4) or squared (1:1, 2:4, 3:9, 4:16) or inverse squared (1:1, 4:2, 9:3, 16:4).
Or for that matter any other dimension (cubed or inverse cubed?)?
I spontaneously think the first is likely : if the cosmic radiation dose is doubled, the speed of carbon 14 production is also doubled.
But suppose I am wrong, I'd like to know.
Hope this may interest you and be worth your time,
sincerely,
Hans Georg Lundahl

- Cosmic Radiation and C14 Production, a Q
- I have asked a question which seems more complicated than I thought.
I was given this paper as an answer, and will read it too:
https://arxiv.org/pdf/1206.6974.pdf
But I saw a summary by the man who gave me the reference.
He said that up to 1 Gev, the relation between energy of cosmic radiation to production of C14 is linear, but above 1 Gev, the relation becomes more like:
energy:production = n:sqrt(n)
This makes me wonder, what level of milliSievert per year is 1 Gev, and what carbon 14 production corresponds to it?
I suppose it is an observed level, but is it medium of the normal production, higher or lower?

- Dear Has-Georg,
Thank you for your interest!
However, I cannot understand you question.
I don't know who is the man who told you that
"up to 1 Gev, the relation between energy of cosmic radiation to production of C14 is linear, but above 1 Gev, the relation becomes more like: energy:production = n:sqrt(n)"
but it doesn't sound clear for me.
Neither do I understand how radiation dose is related to 14C production in your mail.
Could you please formulate it in a clearer way?
For your information, the most recent 14C production model is available here:

Well, I will try to clarify.
Here is a man who gave me the link, he also gave me the resumé:
- Bruno Doussau
- Professeur d'informatique chez Tyumen University
In other words, if he got it wrong, the man is not in your specialty, that is why I am writing you.
He had, as best as he could, tried to answer the question:
La production du nouveau carbone 14 ayant un rapport avec la force de la radiation cosmique, est-il proportionnel directement, au carré ou inversement au carré (détail en commentaire) ?
https://fr.quora.com/La-production-du-nouveau-carbone-14-ayant-un-rapport-avec-la-force-de-la-radiation-cosmique-est-il-proportionnel-directement-au-carr%C3%A9-ou-inversement-au-carr%C3%A9-d%C3%A9tail-en-commentaire
He had also linked to you, so I could read the material myself or check with you.
Obviously, more cosmic radiation equals faster production of C14.
I am less concerned with the energy as measured from cosmos than with how it reflects as radiation doses on earth.
Like, if at a point in time C14 was (not on the calibrations you are using, but on an alternative one) forming 11 times faster than now, and if the normal cosmic radiation on earth is now 0.39 milliSievert per year, would at such an occasion the radiation dose be 11 * 0.39 milliSievert per year, less, or even 121 * 0.39 milliSievert per year?
It makes a certain difference as to how realistic the alternative calibration is, since a radiation dose which kills off all life is not possible to have had in the past.
Thank you for taking your time!

- Re: Cosmic Radiation and C14 Production, a Q
- Dear Hans-Georg (sorry for misspelling your name earlier),
Thanks for the clarification. I think I start understanding your question.
Although indeed, more 14C corresponds to higher radiation dose at Earth, there is no one-to-one relation between 14C production and cosmic radiation dose at the surface.
Exact relation should be calculated using detailed models which do exist but I am not aware of a precise calculation of what you ask.
The problem is that 14C is produced globally, in the entire atmosphere, while radiation is local and at the surface. Their exact relation may depend on many factors, most important being the energy spectrum of cosmic rays (the solar modulation) and the Earth's magnetic field which vary independently of each other. Therefore, the same amount of 14C produced in the atmosphere may correspond to different doses at a given location.
Best regards,
Ilya

- Re: Cosmic Radiation and C14 Production, a Q
- So, for a production 11 times faster (over an extended period), what would be the maximum and minimum of radiation dose at a height* where today the one coming from cosmos is 0.39 milliSievert per year?
Or one for typical solar spectrum?
Or, could you link to some of these models?
- Note
- * As I have read, the medium dose from cosmos is 0.39 mSv (? abbreviation?) and it depends on height.
- XII
- Me to Ilya Usoskin
- 10/30/17 at 3:10 PM
- The 0.39 mSv per year relate to normal C14 production how?
- I mean, at medium height, the normal exposure to cosmic rays is 0.39 mSv, at sea level it is 0.27 mSv.
Suppose now the cosmic rays changed so that the speed of carbon 14 production were 2, 3 or even 11 times as fast, would the exposure at normal height / sea level be:
0.39 mSv / 0.27 mSv per year * 2, 3, 11?
0.39 mSv / 0.27 mSv per year * 4, 9, 121?
0.39 mSv / 0.27 mSv per year * 1.414, 1.732, 3.317?

- Cosmic Radiation and C14 Production, a Modelling Q
- Good day!
Let's suppose all other parameters equal, but following parameters unequal to now, three scenarii:
1) solar activity and galactic radiation 2 times as strong, twice as many incoming particles, Earth magnetic field half as strong;
2) solar activity and galactic radiation 3 times as strong, three times as many incoming particles, Earth magnetic field a third as strong;
3) solar activity and galactic radiation 4 times as strong, 4 times as many incoming particles, Earth magnetic field a quarter of the strength.
In each case, prolong over many years and take it as medium.
In each case, how much faster is C14 produced compared to now, and how much more milliSievert per year would normally be coming from cosmos, as compared to the 0.39 per year at presently known?
I would have thought, spontaneously, the answers would be:
1) 4 times faster, 4*0.39 mSv per year;
2) 9 times faster, 9*0.39 mSv per year;
3) 16 times faster, 16*0.39 mSv per year.
The "11 times faster" being therefore between cases 2 and 3.
If I am wrong, I'd like to know, and you are in a position to tell, as far as I know.
Best wishes,
Hans Georg Lundahl

- Dear Hans-Georg,
I am sorry, I am very busy now and cannot make your exercises.
Moreover, your questions are still imprecise.
> 1) solar activity and galactic radiation 2 times as strong, twice as many incoming particles, Earth magnetic field half as strong;
For example, this sentence does not make sense. "Twice as many incoming particles" in what energy range?
You probably wanted to say that twice as much 14C was produced?
[No, I did not ...]
In order to answer your question, someone needs to run a model with a precise selection of parameters. I don't have time now for that, and I still don't understand your question.
Best regards and sorry for brevity,
Ilya

- Re: Cosmic Radiation and C14 Production, a Modelling Q
- "twice as strong" = twice the normal energy range
AND "twice as many particles"
AND "half as strong a magnetic field"
"You probably wanted to say that twice as much 14C was produced?"
No, I already said I guessed 4 times as much C14 would have been produced, but you know better.
Take your time, whenever you get it.
Above explicitates for 1, with 2 each factor is muliplied by three, with 3 each is multiplied by four.
ALL other parameters equal to normal ones at present.

- Re: Aw: Fw: Cosmic Radiation and C14 Production, a Modelling Q
- Well, I thought the question was clear from the emails already sent below this, but once again:
He has the latest model of how variations in cosmic radiation affect production of C14, Na22 (?), Be7, Be10 and other cosmogenic isotopes.
I thought I had detected a problem in his model (a MONTECARLO simulation programme) for my own model of carbon rise in the atmosphere (a necessity for Young Earth Creationism).
Now, from certain words in our previous exchange (the one I forwarded was the second one), I had gathered it was less straightforward than I thought.
So, I asked him to model first for 2, 3, 4 times as much carbon, then he answered that this was not straightforward as different combinations of parameters could do this.
This provoked a refined (and quantitatively changed) modelling request:
Cosmic radiation (both galactic and solar) : 2, 3, 4 times as many particles coming with 2, 3, 4 times as much energy. Earth magnetic field : 1/2, 1/3, 1/4 present strength.
This I figured would give parameters for Carbon production 4 (or 8), 9 (or 27), 16 (or 64) times as fast as at present in medium. But since it was more complex, as he said, I could be very wrong here.
The other result parameter I would want is, how does this translate in milliSievert per year on a normal height on Earth (at present, with 1*1*1/1 it is 0.27 at sea level and 0.39 at medium height for localities on land/on Earth).
My concern is this : on my model of carbon rise, I would need carbon production to be 11 times as fast as at present during the Babel event (40 years of Babel project correspoinding to 1000 carbon dated years of Göbekli Tepe), as to the rest, my highest C14 production values (for St Jerome's chronology, presuming it has 401 years between Flood and birth of Peleg) are 5-6 times faster at between Joseph in Egypt (supposing he is Imhotep under Pharao Djoser) and fall of Jericho (supposing the Kenyon date of 1550 BC is the one we need for 1470 BC), and a little more than 5 times faster in medium between Flood and Babel.
Here is the latest model involving Usoskin:

- If you’ve had a paper espousing creationist views accepted in Nature or Cell recently, I humbly defer.
- Otherwise I think you’d find raw exposure to a group of people equipped with the education I describe to be an enlightening experience.
- Hans-Georg Lundahl
- Just now
- Oh, you meant educated so as to be brain washed to accept scientific articles only from Evolutionist publications?
- In that case I don’t pick your version of “educated”.
- It is more like Evolution biassed scientists are shunning too much exposure to me.
- I was asking Ilya Usoskin to test my model (not saying it was mine and not giving exact details, but frame work for diverse quantities on three parameters) on carbon 14 build up, and he had no time.
- He is a physicist at Oulu University in Finland, presumably partly Russian and partly Finnish.
- In that case I don’t pick your version of “educated”.
- End cited,
- back to letter:
- If my guess about part Finnish ancestry was bad in relation to name "Usoskin", I'll be happy to rectify.
Equally, if I got your motivation wrong.
Yes, the scenario with 11 times faster C14 production is my own, it is a YEC one.
http://creavsevolu.blogspot.fr/2017/07/how-fast-was-carbon-14-forming-during.html
The reason I want to check with either you or sn else is, as Richard Carrier says:
" a more general error: Not trying to prove your thesis false, before asserting it’s true. "
If 11 times faster carbon production is = milliSievert per year impossible to survive, then my scenario is proven wrong.
I had got this challenge a few years ago, at Nanterre University campus, after working in the library, but my solution had so far been assuming the incoming cosmic radiation is linear graph proportional to the production of new carbon.
So, I assumed, you are not interested in helping me check, because you figured out I am Young Earth Creationist, and because you have some prejudice against the position.
Even so, others have a stronger one, some have on other issues not even answered a first time. Or even on this one.
Thanks, and feel welcome to ask for a correction in the mention, if you like!

- Dear Hans-Georg,
As I said, I am very busy now and unfortunately have no time for your exercises.
Still, the problem was posed unambiguously. A direct comparison between 14C (which is global) and radiation dose (local) does not make sense unless the exact location is specified. There are some other unclear moments, but this is the main one. The dose at equator and polar regions would behave differently in relation 14C global production.
You are free to write whatever you want in your blog, but I don't think I gave you any reason to accuse me in any "prejudice".
I am not interested in your believes and aims, I am a scientist and more interested in facts than in believes.
My nationality is irrelevant in this discussion.

- "Still, the problem was posed unambiguously. A direct comparison between 14C (which is global) and radiation dose (local) does not make sense unless the exact location is specified."
OK, I ditched the "go from C14 production" in response to what you said and instead I gave certain parameters :
- I cosmic radiation both galactic and solar a) 2*particles and 2*energy per particle, b) 3* etc, c) 4* etc
- II earth's magnetic field a) 1/2 as strong, b) 1/3 as strong, c) 1/4 as strong.
In each case, compared to medium value now.
I asked what would be speed of carbon production (global, as you may guess) and what would be the (global, I thought) effect in radiation dose.
I now correct this to :
I asked what would be speed of carbon production (global, as you may guess) and what would be the effect in radiation dose, both for equator and for pole.
How long could it take to program this into the monte-carlo model?
If you have no time, could you delegate it to a student, please?
"I don't think I gave you any reason to accuse me in any 'prejudice'."
Without prejudice, why:- do you persist in relating to my initial request instead of to my corrections of it?
- do you state you are not interested in my beliefs, when I was asking a question pertaining to (modelled) fact?
"My nationality is irrelevant in this discussion."
Perhaps it might remain so, I wanted to give you a chance to correct, if you thought appropriate.
