You don't see my problem here? Olive Branch : ) [/quote] Oh, I see your problem. An unwillingness to do hard numbers. [/quote] Me,a Mathematician,no. Understands Radiation damages Film,yes. [/quote] How MUCH radiation damages what KIND of film how MUCH? Are you aware that different speeds of film react differently to ionizing radiation? Do you know it was quite possible even during the days of foil bags and checked luggage to pass exposed film through airport X-rays and not have any noticeable degradation? Are you aware that the film significantly at risk is that which is exposed then stored for long periods undeveloped? When you say "radiation damages film" you are saying the same as "water kills people." That doesn't mean the glass of water on my table is going to kill me (although it could, given the right chain of circumstances!) Science is not word pictures. Engineering is not done with adjectives. If you can't quantify, then you are left trying to decide if "Significant" risk is bigger or smaller than "Adequate" protection. Or, worse yet, if "some" degradation of exposed film is equivalent to "I see marks on all the film." [quote:Spittin'Cesium:MV8yMTU0NzQ4XzM2NDU2NzMyXzRDQTY5ODFD] Understands Space within the Solar System is loaded with Ionizing Radiation. [/quote] Loaded is a loaded term. It is emotional, not informative. The surface of the Earth is loaded with radioactive materials (in relation to most other solar system bodies.) Does that mean lumps of pure U235 are lying around loose? [quote:Spittin'Cesium:MV8yMTU0NzQ4XzM2NDU2NzMyXzRDQTY5ODFD] Understands the Moon is a Large Secondary Gamma Source on Earth,second(as a constant)to the Sun. [/quote] Rubber bands are a fine power source for vehicles, second to compressed air. Doesn't mean either are that good. The Sun is a poor source of gamma rays. I'd have to do the numbers, but you'd probably put your film in more danger by laying a banana on top of it. [quote:Spittin'Cesium:MV8yMTU0NzQ4XzM2NDU2NzMyXzRDQTY5ODFD] 'Today, these gamma-ray bursts, which happen at least once a day, are seen to last for fractions of a second to minutes, popping off like cosmic flashbulbs from unexpected directions, flickering, and then fading after briefly dominating the gamma-ray sky'http://science.hq.nasa.gov/kids/imagers/ems/grb_animation.gif ' The Crab nebula, shown also in the visible light image, was created by a supernova that brightened the night sky in 1054 A.D. In 1967, astronomers detected the remnant core of that star; a rapidly rotating, magnetic pulsar flashing every 0.33 second in radio waves. Perhaps the most spectacular discovery in gamma-ray astronomy came in the late 1960s and early 1970s. Detectors on board the Vela satellite series, originally military satellites, began to record bursts of gamma-rays -- not from Earth, but from deep space' 'If you could see gamma-rays, the night sky would look strange and unfamiliar. The gamma-ray moon just looks like a round blob - lunar features are not visible. In high-energy gamma rays, the Moon is actually brighter than the quiet Sun. This image was taken by EGRET'http://science.hq.nasa.gov/kids/imagers/ems/moon_egret.jpg . Ffs. [/quote] Yup. Gamma-ray astronomy (astronomers like to hyphenate the term). There is also infrared astronomy, and radio astronomy. Does that mean extra-terrestrial radio sources swamp everything on Earth, making even a simple cell phone call impossible? (Well, yes, it can happen -- space weather as well as local weather can cause significant interference.) But the sources tracked by radio astronomy....well, let us put it this way; is your cell phone antenna a 305-meter dish? (aka Arecibo). Or even a 40-meter dish? (aka Parkes). Again, knowing that it is out there is nothing like knowing if it is strong enough to, say, harm a piece of film. [/quote] You know and I know that Radiation is damaging to Film,I do not need to even really need to quantify that fact. The issue is 'How Much' and 'What Kind'. '[color=red][Moderator: Banned for denial of scientific expertise and substituting conspiracy hypotheses, confirmation bias and Dunning-Kruger overconfidence.][/color]'http://lofi.forum.physorg.com/Moon-Landing-Conspiracy-Battles_39352.html <--- Have a read of that attempted discourse:chuckle: These are the types of issues I want to understand better,I'd like to believe we went to the Moon after-all. Excuse my lazy response,I'm knackered...and I am not a Film expert either. :sun: [/quote]

NASA discovers NEW Van Allen Belt!
So, if we didn't know about this, what else don't we know about?

...and how could we get through it safely on our way to the moon??
