Noob q: wouldn’t that be the case only for radiation coming along the body axis? If tin foil reflects these waves at all, having the radiation come from other angles should make it less bad, no? Like if they come face-on, they won’t catch any of the concave part of the “dish” and be scattered away instead.
- detaro 5y agoIt was mostly a joke, but there is still a focusing effect for sources that are off-axis, so it'd really depend on direction and shape of the foil hat. e.g. if it covered a lot of the back of the head but left the face open, like a crash helmet, the main axis wouldn't be straight down, for a tinfoil cap it would be.
