It sounds to me like a bit of 'reverse engineering'. Percy goes to Groves and asks for data concerning how much radiation is necessary to fog the film. He then uses this data to feed back in radiation values into his argument.

Film fogs at 25 rems, so for our argument to succeed, cislunar radiation must be at that level. This would fog the film. (It would also make the astronauts ill, damage the spacecraft electronics, etc etc, blah blah). Trouble is, the universally accepted values are nothing like this high, not even close.

I left my laptop in the car yesterday, and the sun came out. It's in a bag. It's also got a shiny metal cover, and it was in the footwell, in the shade. The inside of the car was roasting when I got in it. You know, when you can't even hold the steering wheel it's so hot. I took the laptop out of the bag to check it hadn't melted or anything, and it was cold. Obviously, some strange advanced cooling system has been developed by Samsung to keep their laptops cool in cars. Or it could have been in a bag in the shade. You decide.

(More twisting of the truth from John Witts)

BTW, Nice of you to type in the whole of page 540 from 'Dark Moon'.
