gamma, which would be the least/most harmful to biology and why?
Which would be the easiest/hardest to block and how?
2. In some medical procedures, radioactive isotopes are used
that have very short half-lives. Why is this desirable and how
would these isotopes be obtained since none would be found in
supply due to their short half-life?f

For 2 MeV alpha, beta, and gamma emissions calculate the following quantities relativistically for each emission:...
For 2 MeV alpha, beta, and gamma emissions calculate the
following quantities relativistically for each emission: T (Kinetic
Energy), E (total energy), gamma (correction factor), p (momentum),
m (mass), and v (frequency). Use nuclear units, i.e., keV or MeV
for energies, keV/c or MeV/c for momenta, MeV/c2 for masses and
express velocities in units of c.

4) A nucleus of radioactive radium (226Ra), initially at rest,
decays into a radon nucleus (222Rn) and an alpha-particle (a 4He
nucleus). If the kinetic energy of the alpha-particle is 6.72 × 10^
-13 J, what is (a) the recoil speed of the radon nucleus, and (b)
its kinetic energy? The superscripts indicate, roughly, the mass of
each nucleus in unified mass units (u), where 1 u = 1.66 × 10^ -27
kg.
