gamma, beta and alpha radiation are all alike because:
they all have the same mass
they all have the same charge
they all can be emitted from the nucleus of an atom
they all have the same energy

alpha, beta and gamma radiation all show different levels of penetration because:
they have different energies
they have different frequencies
they have different wavelengths
of all of these reasons

when an atom releases an alpha particle:
the atom's mass number decreases by 4
the atom's mass number decreases by 2
the atom's mass number increases by 4
the atom's mass number increases by 2

nuclear decay by beta particle emission is more common in atoms of elements that:
have an atomic number greater than 83
have a high proton to neutron ratio
have a high neutron to proton ratio
have a low proton to neutron ratio

einstein's formula tells us the amount of energy to which a given mass would be equivalent, if it were all suddenly turned into energy.

according to alex gabbard, in "coal combustion: nuclear resource or danger," a recent report from oak ridge national laboratory concludes that coal power actually results in more radioactivity being released into the environment than nuclear power operation, and that the amount of radiation to which the public is exposed is 100 times greater than that of the ideal operation of a nuclear plant. the most likely rationale for this statement is:
there are currently more nuclear power plants in operation than coal-fueled power plants.
coal ash is released directly into the environment whereas nuclear waste is shielded.
coal ash is more radioactive than uranium waste.
both choices b and c

although some waste disposal facilities are located adjacent to the facilities they serve, using one disposal site to manage the wastes from several facilities is usually preferred because this would:
let potential residents to the area know of its location before moving there
reduce the overall environmental impact of the waste by consolidating it
neutralize some of the "old" radiation by addition of "new" radioactive materials
allow for the ongoing and "hands-on" safety training of both new and veteran truck drivers
