Latest Already Graded A+ UPDATE 2026|2027
ionizing EM radiations - (ANSWER)x-rays, gamma rays, & high energy ultraviolet
what causes biologic damage to living cells - (ANSWER)ionization
Describe the relationships between energy, wavelength, & frequency of EM radiations. - (ANSWER)•The
energy & frequency of photons are directly proportional. As frequency increases, energy increases
proportionally (& vice versa)
•However, wavelength & energy are inversely proportional. As wavelength decreases, energy increases
proportionally (& vice versa)
Properties of X-Rays - (ANSWER)•Are a form of EM radiation (energy)
•Can ionize matter
•Travel in straight lines at the speed of light
•Cannot be seen or heard
•Are electrically neutral & have no mass or charge
•Are not affected by electric or magnetic fields
•Can be produced over a wide range of energies & wavelengths
•Release a small amount of heat when passing through matter
•Cannot be reflected or focused by a lens
•Cause fluorescence of certain crystals
•Produce secondary & scatter radiation
•Produce chemical & biological in matter through excitation & ionization
a# - (ANSWER)# (atomic mass number) = nucleon
(protons + neutrons)
z# - (ANSWER)# (atomic number) = proton
