Yes, enough of it can. But boron or cadmium would be better.
Not completely. The gamma and neutron radiation are the hardest to stop, and they can really only be attenuated. It typically takes a few feet of most metals to attenuate gamma to safe exposure levels and denser metals are always better (titanium is not all that dense). Neutron radiation is not effectively attenuated except by strong neutron absorbers like boron and cadmium. Reactor shielding is typically composed of alternating layers of a couple inches of lead plate and a foot or so of borated concrete, until sufficient attenuation has been obtained for both gamma and neutrons.
It does if you want to detect the beta radiation. Beta radiation, beta particles, can be stopped with a sheet of aluminum foil. An aluminum "absorber" would act as a shield to the Geiger-Müller (GM) detector and stop the beta radiation, which is really high energy electrons or possibly positrons. Placing a shield between the source of the beta radiation and the GM detector would block the radiation, thus shielding the detector from it. The detector would be "blind" to the radiation. Note that this would be effective if all you wanted to do was look at gamma rays. The gamma rays and the beta radiation would leave the source and head to the GM detector, the beta particles would be blocked by the aluminum, and only the gamma rays would make it to the GM tube to be counted.

Yes, a positron has penetrating power, but not very much. The positron is an anti-electron (antimatter), and it will have little power to penetrate anything, even at high energy. A thin sheet of aluminum foil will stop it. But there is a problem. As far as radiation goes, the positron will not travel far before it will slow down in a series of scattering events, and then find an electron to combine with in mutual annihilaton. This will realease two extremely energetic gamma rays. And they can penetrate stuff big time. They present a radiation hazard.
A lot of things, but I think you might be referring to which form of radiation since this is the classic answer as to what would stop Alpha radiation. Furthermore tinfoil would stop alpha and beta radiation and lead would stop alpha, beta and gamma radiation.
radiation
I believe anodized aluminum does whereas plain aluminum does not
aluminum foil it seals the cold in alot more than plastic wrap.ans2, RIGHT answer, but reason not quite correct. The shiny aluminum will reflect all heat.And since your package is cold, the only ways it can heat up are conduction, radiation, and convection. Of which three, Aluminum foil will stop radiation and largely stop convection.
No there is no material discovered which can stop the penetration of gamma radiations
penetration does not effect menstruation in any way

hi it is a combination of Be/Po210 . po210 emits an intensive alfa radiation and when this radiation contact with Be metal foil, the result would be neutron. as you know neutron is critical element to make chain fission reaction .so in practice a very thin gold foil can stop alfa radiation but if an explosion mix po210 with Be, we will have a high intense neutron source can trigger a ultimate fission bomb. a good design of initiator help to make a smaller and effective bomb with high yeild. the size of an initiator would be a grape size. if you have any more question don't hesitate to ask contact mail:annafarahmand@yahoo.com

It depends on what kind of radiation... Alpha radiation can be stopped with a sheet of paper or a few inches of air. Beta radiation can be stopped with a thin sheet of metal. Neutron radiation, depending on energy, requires large thicknesses of lead or concrete. Gamma radiation, depending on energy, also requires large thicknesses of lead or concrete. Some of the higher energy gammas, such as cosmic rays, can be quite difficult to stop at all.

What happens here is that while the star is converting energy through nuclear fusion, the inward force of gravity is countered by (a) the gas pressure, and (b) the radiation pressure. However, once the nuclear fuel burns out, there is no more radiation pressure; and the gas pressure by itself is not enough to stop the collapse. Thus, the star will collapse - into a white dwarf, a neutron star, or a black hole, depending on the remaining mass.
