[quote:Anonymous Coward 2380183:MV8yNjgyMjA5XzQ4NzIxNTIyX0VFMDY1NjQw] [quote:Anonymous Coward 67748437:MV8yNjgyMjA5XzQ4NzIwNDU3XzY4NTMzOTVB] Two points, the time required to get to the moon from the Earth was far more than the 12 hours you're claiming (237,000/20,000=@12 hrs), meaning the velocity was much lower than 20,000mph. [/quote] It's a transfer orbit, not a trip down the highway. You can't do simple division to figure out velocity specific to any of the bodies in question. [quote:Anonymous Coward 67748437:MV8yNjgyMjA5XzQ4NzIwNDU3XzY4NTMzOTVB] Also, it is impossible for Apollo to have penetrated the VAB at any latitude other than the one it was launched at because it had to intersect the moon's orbit in essentially the same plane it orbits Earth to have the equatorial orbit of the moon it did and land at the Sea of tranquility. [/quote] More complex than that. The Moon's orbit is neither aligned with Earth's equator, nor the ecliptic. Nor is the Cape on the equator; launches from there are not equatorial either (much less aligned with the solar ecliptic). [quote:Anonymous Coward 67748437:MV8yNjgyMjA5XzQ4NzIwNDU3XzY4NTMzOTVB] The best case scenario is 38 degrees latitude, in the thick of the VAB which BTW are extremely variable and vary from minute to minute. Radiation densities are given as averages. [/quote] Yes; as weighted averages. Which means the excursions are known numerically and statistically. When you say freeway speeds average 70 MPH, that doesn't imply cars frequently travel at 200 MPH. And it certainly does not allow that every now and then, a car passes at relativistic velocity. [quote:Anonymous Coward 67748437:MV8yNjgyMjA5XzQ4NzIwNDU3XzY4NTMzOTVB] Plastic and insulation can stop SOME particle radiation. They have little effect on electromagnetic radiation or high energy particles. [/quote] Everything has a half-thickness. Even dead skin, or nomex coveralls. This is why qualitative statements are misleading. [quote:Anonymous Coward 67748437:MV8yNjgyMjA5XzQ4NzIwNDU3XzY4NTMzOTVB] The aluminum hull woudl make the problem worst,because particle radiation produces deadly x radiation when it impact aluminum. It also produces secondary particle radiation from the nuclei of aluminum atoms. [/quote] Which is desired behavior. The secondary emissions are of lower energies and are largely stopped in the remainder of the material (or the following layers). For an education in how this works, look at the Therac-25 incidents. And remember these were therapeutic machines specifically designed to utilize bremmstrahlung to maximum effectiveness. Yet, the patients who died, died from the original electron beam, NOT from the generated x-rays. [quote:Anonymous Coward 67748437:MV8yNjgyMjA5XzQ4NzIwNDU3XzY4NTMzOTVB] While in the VAB the Apollo spacecraft would be bathed in electromagnetic radiation many times more powerful than an x ray machine or microwave oven is, which penetrates a body easily. It also important to understand x ray exposure in medicine is limited to a fraction of second because x radiation is in fact extremely harmful to living things. This is why I am reluctant to be x rayed, because I believe a person could easily be killed by a malfunction.. [/quote] See Therac-25, above. Numbers, that's what's important. You wave your hands and simply claim that because so and so source exist, the Apollo capsule "Must" have been exposed to a searing hell. I am within miles of research reactors, tens of miles of power reactors. The local rock formations include natural uranium, and the so-called "radon daughters" (a collection of active radionuclides from the various decay chains) are known to collect in basements. There is detectable nuclear fallout in the soil, in fact, in the metals I work and in my very bones. There are cosmic ray showers. I have worked around multiple sources of hard x-rays with not always adequate shielding, and recently, too. The very sun is a source of x-rays. I can generate x-rays -- x-rays with sufficient penetrating power to expose photographic film! -- [i]simply by unrolling a strip of tape.[/i] This is why numbers are important. ALL of the above are non-zero hazards. In fact, several of them are known -- have been shown in large-scale studies -- to reduce my life expectancy by a measurable amount, and to mutate any progeny I might have. But this does not make my continued existence a hoax. Until you can quantify the actual hazards, show the energy distribution and flux and apply the half-thicknesses correctly, you are making nothing but empty claims. [/quote]

Watch this NASA video, 3 minutes in he says this about the Van Allen Radiation Belts: "We must solve these challenges before we send people through this region of space"
