So if we could shield out all other radiation we could survive for days standing on a Sunspot and suffer no long term ill effects? I second Tedward's request. I will represent to you that the LD 50/30 dose for gamma rays is 450 rem. Please compute for us, based on data you have and/or additional data you can acquire by some means except asking here for it, Buzz Aldrin's whole-body dosage after 2 hours of exposure on the lunar surface. I expect from you an actual number measured in rem. Perhaps then you'll learn the difference between amounts of radiation that are merely detectable by our instruments and the amount that is actually of any biological significance.

Well, the atmosphere counts for something. Life on the ISS would be a bit more exciting, though. What about the Van Allen belts also? What about them? Have you researched their effects? Are you aware Van Allen worked for NASA on the Project? No. Instead you now have three threads running and you continually raise new issues without defending your previous claims. Its a common HB tactic. Remember the falling astronaut video? The poster awaits your explanation of that. But we know you can't, so your alternative is to move onto something else. Now you move into the White thread and start going OT to derail that one. Mods - Ban stick. He is not interested in debating the issues or defending his claims.

I looked to quantify the radiation but initial searches did not offer this info. And therein, rodin, lies the reason you are being discounted a serious researcher here. It is your responsibility to do that research before putting up claims based on it. Once again, 'could be'. Do you ever intend to offer any evidence for any of your claims? I was able to find the numbers that go with that image, and you know what, it's not significant. The Moon also shows up in the sky as a bright light source. Inverse square yourself all the way to the surface and by your logic anyone walking around there should be blinded by the light. And here is the fundamental reason your 'inverse square yourself all the way to the surface' argument is a load of tosh: as you get closer the radiation intensity increases by the inverse square, but so does the apparent size of the surface over which you are seeing it spread. The two effects cancel quite well.

What about the Van Allen belts also? Irrelevant to a discussion about gamma rays.

Rodin. As can be seen in the info that goes with your picture, it is showing reflected Gamma Rays. Those same gamma Rays are hitting the Earth and we are doing just fine.

What do you guys all expect from a guy who can't even tell that a video with time code display on youtube is the same one made available explicitly for him on a thread he started?

What about the Van Allen belts also? What point are you trying to make and the VARB? That the field may attenuate/divert incoming gamma rays.

Rodin, I suggest you go and read some basic information about gamma radiation and the van Allen belts. Then you might realise how absurd that statement is.

Actually its both The same article states which if true means that gamma radiation from the Moon's surface is very weak indeed - almost indistinguishable from background I refer you to the picture in the OP where the gamma radiation is very distinguishable from background. en.wikipedia.org/?title=Lunar_Prospector

The Van Allen Belts interact with charged particles, but have no effect whatsoever on short-wavelength EM radiation (which gamma rays, x-rays, UV and visible light all are).

The same article states which if true means that gamma radiation from the Moon's surface is very weak indeed - almost indistinguishable from background I refer you to the picture in the OP where the gamma radiation is very distinguishable from background. How was that picture generated? Could it be that multiple images were stacked and noise reduction techniques used to overcome that issue and make the lunar gamma rays stand out from the background? Noise reduction is a standard technique to tease out low signals from the background.

Come on, you the one pushing this, show me its lethal.
