What is a radionuclide?
,Ans- A nuclide that emits particular or photon energy to achieve a more stable
energy state
Another name for a helium ion containing two protons and two neutrons is?
Ans- an alpha particle
What is a beta particle?
Ans- An electron
Why are alpha particles and beta particles not used for imaging?
Ans- They do not exit the body efficiently and thus are not detected
What ratio of protons to neutrons favors beta decay?
Ans- A low proton-to-neutron ratio, as compared with stable nuclei
What two particles are emitted from the nucleus during beta decay?
Ans- A beta particle (electron) and an antineutrino
,What is the relationship between the mean energy of beta spectrum?
Ans- The mean energy is approximately one third of the maximum energy
What ratio of protons to neutrons favors positron decay?
Ans- A high proton-to-neutron ratio
What particles are released from the nucleus during positron decay?
Ans- A positron (antielectron) and Neutrino
What is the minimum amount of nuclear energy required for positron decay?
Ans- 1.02MeV
What is the fate of a positron?
Ans- To travel a short distance, combine with an electron, and be annihilated
, When a positron is annihilated via combination with an electron, the result is the
production of?
Ans- Two nearly opposed 511 keV photons
What ratio of protons to neutrons favors electron capture decay?
Ans- A high proton-to-neutron ratio
What particle is released from the nucleus during electron capture decay?
Ans- A neutrino
What is released from the nucleus during isometric transition?
Ans- Gama rays
Other than wavelength, frequency, and energy intensity, the fundamental
difference between X-rays and gamma rays is?
Ans- that x-rays are produced from energy released due to changes in the
quantum levels/values of orbital electrons of an atom, while gamma rays are
produced from energy shifts in the nucleus
