2010-5-25 I'm having a discussion with my roommate. His opinion is that only lead will block x-rays. I think anything will block x-rays, if it's dense enough or thick enough. So I'm sure that aluminum foil will block the x-rays used to x-ray packages going through the Post Office. So I guess the question i...
Ah, the Superman theory. "I have trouble seeing through lead." Technically, nothing "blocks" x-rays. What you have is an attenuation which is an ex...If they use anything like the fluoroscopes we use in lab, maybe 8-9 layers or a thick baking sheet style foil should prevent most of the damage.

It's aluminum foil - tin hasn't been used in years. X-rays can't see through led. But I would disguise what ever I was sending rather than mask it. If you ever looked at an x-ray image, you can't really tell what anything is. I would worry more about odor. O.
2011-11-26 Very dense materials generally block x-rays well. Lead and tungsten are frequently used. Of course, if you put these in your luggage at an airport, you'd be pulled aside for "extra screening," since having a chunk of lead in your luggage is a sign that you're trying to hide something.

2021-11-16 Aluminum foil will block the x-rays that the postal service uses. But most metal detectors won't notice the aluminum foil. That means you can't hide something else with foil at the airport, and if someone uses x-rays they will see a big blank spot and make you open the suitcase up anyway.

2021-5-28 Yes, metal detectors do detect aluminum. That's the short answer, but it's so much cooler than that so read on! As with any metal, other factors come into play. Obviously, the type of metal is important, but the size, orientation, shape, and soil

Airport scanners work based on the X-ray radiation — a high-energy electromagnetic radiation. X-rays in simple terms are a beam of high energy “light”. The beam is blocked (attenuated) by every material substance to some degree and comparisons are made between the level to which two or more substances block this beam.
