E. Both Xrays and gamma rays can pass through, but they can cause damage when they do. Alpha particles are helium nuclei (two protons and two electrons) and are big enough that almost any material stops them. Beta particles are electons, and they are generally of low enough energy that the particles in the body would stop them. It may be that whoever is asking the question just wants to emphasize the difference between particles and rays.

Answer: E

Because of their high energy, gamma photons travel at the speed of light and can cover hundreds to thousands of meters in air before spending their energy. They can pass through many kinds of materials, including human tissue. Very dense materials, such as lead, are commonly used as shielding to slow or stop gamma photons.

Both direct (external) and internal exposure to gamma rays or X-rays are of concern. Gamma rays can travel much farther than alpha or beta particles and have enough energy to pass entirely through the body, potentially exposing all organs. A large portion of gamma radiation largely passes through the body without interacting with tissue--the body is mostly empty space at the atomic level and gamma rays are vanishingly small in size. X-rays behave in a similar way, but have slightly lower energy. By contrast, alpha and beta particles inside the body lose all their energy by colliding with tissue and causing damage.

Gamma rays can ionize atoms in tissue directly or cause what are known as "secondary ionizations." Ionizations are caused when energy is transferred from gamma rays to atomic particles such as electrons (which are essentially the same as beta particles). These energized particles then interact with tissue to form ions through secondary ionizations. Because gamma rays are photons and thus interact less frequently with matter than alpha and beta particles, they are more penetrating and the damage they cause can occur much farther into tissue (that is, farther from the source of radiation).

A and B easily, D with difficulty. That being said, the beta electrons for the decay of Cobalt 60 can zip right through you (1.2 MeV), and those produced in accelerators can be made to pass through tens of feet of leaded concrete.

alpha can only penetrate through some layers of skin so no
beta can penetrate some level of body
gamma goes through body
depends the level/intensity of Xray..if it is a multiple answer then would be a and b...if single answer than only A

CLASSICAL ANSWER:
E

QUANTUM ANSWER:
All. Due to the heisenberg uncertainty principle, alpha and beta rays can pass through your fingers if their speed can be measured very accurately.
