14 Questions
Which type of radiation disrupts the atomic structure of the absorber, causing chemical and biological changes?
Directly ionizing radiation
What is the average amount of energy that a particular radiation imparts to the local medium per unit length called?
Linear energy transfer (LET)
In diagnostic radiology, which two processes occur during X-ray photon absorption?
Compton and photoelectric absorption processes
Which process dominates at higher energies?
Compton process
Which process is important at lower energies?
Photoelectric process
Which process varies rapidly with atomic number (Z)?
Photoelectric process
Which process interacts with atomic nuclei rather than electrons?
Spallation process
Which type of radiation is directly ionizing?
Alpha particles
What is the process by which X-ray photons interact with free electrons, transferring some of their energy as kinetic energy to the electron?
Compton process
What is the dominant process at high energies during X-ray photon absorption?
Compton process
Which process is dominant for radiations with high linear energy transfer (LET), like neutrons or α-particles?
Direct action
Which type of radiation interacts with other atoms or molecules in cells, especially water, producing free radicals that can damage critical targets?
Indirect action
What is the primary target for radiation in Radiation Biology?
DNA
Which process interacts with a bound electron in the atom's shell, transferring all its energy to the electron?
Photoelectric absorption
